Supplemental Inflatable Restraint System Deactivation Procedures Buick Century VI

SPECIAL CARE DURING MECHANICAL REPAIRS

In some instances, it may be necessary to remove the steering column or instrument panel to access electrical components. Observe specific manufacturer SERVICE PRECAUTIONS when working on a vehicle with an air bag system.

Electrical power sources should NEVER be allowed to contact the inflator on the back of the air bag module. NEVER probe air bag system electrical wires with an analog volt-ohmmeter or test light. Always disable air bag system before servicing vehicle. See appropriate DISABLING & ACTIVATING AIR BAG SYSTEM procedure. Failure to disable system properly may result in accidental air bag deployment and possible personal injury.

If air bag system is not fully functional for any reason, DO NOT drive vehicle until system is repaired and functions properly. DO NOT remove bulbs, modules, sensors, or other air bag components which will prevent air bag system from operating as designed. If air bag system is not functional, park vehicle until system is repaired and functions properly.

CHRYSLER

All Chrysler vehicles are equipped with driver and passenger side air bags. In addition, some models may be equipped with front seat belt tensioners, left and right front seat side air bags and/or left and right curtain air bags. Unless specific models are mentioned, the following procedures apply to all models with an air bag system.

Except Sebring Coupe & Stratus Coupe

1. Connect DRB-III scan tool, or equivalent, to Data Link Connector (DLC). DLC is located on the driver side lower edge of the instrument panel near steering column. Ensure latest version of DRB-III scan tool software cartridge is being used.
2. Turn ignition switch to ON position, with engine off. Exit vehicle with DRB-III scan tool. Ensure no one is inside vehicle, then reconnect negative battery cable.
3. Using DRB-III scan tool, read and record any active (current) or stored (historical) Diagnostic Trouble Codes (DTCs). Using DRB-III, erase all stored DTCs. If an problems exists, DTCs will not erase. If DTCs are found, perform diagnosis and repairs as necessary. If all DTCs are erased, go to next step.
4. From outside of the vehicle, and away from air bags, turn ignition off for about 15 seconds, then back to ON position. Observe AIR BAG warning light.
5. AIR BAG warning light should come on for about 6-8 seconds, then go out, indicating system is functioning properly. If AIR BAG warning light either fails to come on, blinks on and off, or comes on and stays on, a system malfunction exists. Diagnosis and repair air bag system as necessary.

Sebring Coupe/Stratus Coupe

1. SRS-ECU monitors SRS system and stores data concerning any detected faults in the system. When the ignition switch is turned to ON or START position, SRS warning light will illuminate for about 7 seconds and then turn OFF. This indicates that the SRS system is in operational order.
2. If the SRS warning light does not illuminate, stays on for more than 7 seconds or illuminates while driving, there is a malfunction. Perform diagnosis and repairs as necessary.

SERVICE PRECAUTIONS

This air bag system is a sensitive, complex electronic unit. Before attempting to diagnose or service any air bag system or related steering wheel, steering column or instrument panel components, the following precautions should be observed

1. Disable air bag system before servicing any air bag system or steering column component. Failure to do this could result in accidental air bag deployment and possible personal injury. See «DISABLING & ACTIVATING AIR BAG SYSTEM»(/buick/century/vi-1997-2005/remont/airbag/#supplemental-inflatable-restraint-system-deactivation-procedures__disabling-activating-air-bag-system) .
2. Wait at least 2 minutes after disconnecting and isolating negative battery cable before servicing air bag system. Servicing air bag system before 2-minute period may cause accidental air bag deployment and possible personal injury.
3. ALWAYS maintain a safe distance from all air bags when activating air bag system.
4. DO NOT turn passenger side air bag ON/OFF switch while ignition is in RUN position. This action will set active and stored DTCs.
5. When reconnecting air bag system components, ensure ignition is in OFF or LOCK position and negative battery cable is disconnected and isolated.
6. DO NOT use any electrical test equipment on or near SRS components unless specified to do so. DO NOT use an analog ohmmeter. Use a DVOM with a maximum test current of 2 milliamps or less, at minimum resistance measurement range.
7. After deployment, air bag surface may contain sodium hydroxide deposits, which may irritate skin. Sodium hydroxide is a product of gas generant combustion. Always wear safety glasses, rubber gloves and a long-sleeved shirt during clean-up. Wash hands using mild soap and water.
8. Because of critical system operating requirements, DO NOT try to service any air bag components. Manufacturer recommends that defective components should only be replaced with NEW, original equipment parts. DO NOT use salvaged air bag components or other parts. Substitute parts may appear interchangeable, but internal differences may result in inferior occupant protection.
9. Factory installed fasteners have a special coating and are specifically designed for air bag components. Manufacturer recommends using NEW, original equipment replacement fasteners. DO NOT use substitutes or salvaged parts.
10. Clockspring must be replaced if driver's air bag is deployed.
11. Each time a connector is disconnected, ensure it is clean and not damaged. Always pay particular attention to circuit being tested. Dirt, water and corrosion are the most common problems in connectors, causing voltage drop, open circuits and other improper operations.
12. When performing electrical tests, prevent accidental shorting of terminals. Such shorts can damage fuses or components and may cause a second fault code to set, making diagnosis of original problem more difficult.
13. After repairs are complete and ignition is turned to RUN or ON position, stay clear of air bag(s) to avoid injury in case of accidental air bag deployment.
14. Wear safety glasses, rubber gloves, and long sleeved clothing when cleaning powder residue from the vehicle after an air bag deployment. Sodium hydroxide powder residue emitted from a deployed air bag can cause skin irritation. Flush affected area with cool water if irritation is experienced. If nasal or throat irritation is experienced, exit the vehicle for fresh air until the irritation ceases. If irritation continues, see a physician.
15. Some models use 2 stage deployment inflators on driver and passenger air bag modules. If stage one was used to deploy a dual stage inflator module, stage 2 may still be active. Therefore, a deployed 2 stage air bag inflator module must be treated as an active module. When deactivating an air bag system with deployed air bags, a deployed 2 stage air bag may still be active. If disposal of a deployed or undeployed dual stage module is required, both deployment loops must be energized to deploy the air bag.
16. Deployed front air bags may or may not have live pyrotechnic material within the air bag inflator. DO NOT dispose of air bags unless complete deployment has occurred. Dispose of air bags (deployed and undeployed) in a manner consistent with state, provincial, local and federal regulations.
17. Ensure air bag warning light is operating properly and system faults are not indicated. See «SYSTEM OPERATION CHECK»(/buick/century/vi-1997-2005/remont/airbag/#supplemental-inflatable-restraint-system-deactivation-procedures__system-operation-check) .
18. When placing a undeployed (live) air bag on a bench or other surface, always face air bag and trim cover up, away from surface. This will reduce motion of module if accidentally deployed.
19. When carrying a undeployed (live) air bag module, point trim cover away from your body to minimize injury in case of accidental deployment.
20. DO NOT use a replacement air bag module that is not in the original packaging, improper deployment and personal injury can result. Air bag module must be stored in its original special container until used for service. It must be stored in a clean, dry place, away from sources of extreme heat, sparks and electrical energy.
21. The Air Bag Control Module (ACM)/Occupant Restraint Controller (ORC) contains an air bag sensor which enables SRS to deploy air bags. If air bag control module is dropped, struck or kicked, it can damage air bag sensor or affect its calibration. If air bag control module is dropped, it must be replaced with a NEW unit.
22. DO NOT connect ACM/ORC connector while battery is connected. Ensure ACM/ORC and mounting bracket are securely installed to vehicle before connecting electrical connector.
23. On vehicles with side air bags, use caution when working around "B" pillar or side air bags.
24. Electrical sources should never be allowed near air bag module connector.
25. On Dakota, Durango, Neon, Ram Truck and Ram Van, passenger air bag module contains an Argon gas canister. Canister is pressurized to more than 2500 psi. DO NOT puncture, incinerate, or bring into contact with electricity. DO NOT store at temperatures above 200°F (93°C).
26. On Caravan, Neon, Town & Country and Voyager, passenger air bag and seat air bag modules each contain an Argon gas canister. Canister is pressurized to more than 2500 psi. DO NOT puncture, incinerate, or bring into contact with electricity. DO NOT store at temperatures above 200°F (93°C).
27. On Sebring Sedan, Sebring Convertible and Stratus Sedan, the driver air bag, passenger air bag, seat air bag modules and curtain air bag modules (if equipped) each contain an Argon gas canister. Argon gas canisters are pressurized to more than 2500 psi. DO NOT puncture, incinerate, or bring into contact with electricity. DO NOT store at temperatures above 200°F (93°C).
28. If SRS is not fully functional for any reason, vehicle should not be driven until system is repaired and functions properly. DO NOT remove bulbs, modules, sensors or other components, or in any way disable system from operating normally.

DISABLING & ACTIVATING AIR BAG SYSTEM

Disabling System (Except Sebring Coupe & Stratus Coupe)

1. Ensure ignition switch is in OFF or LOCK position. Disconnect and shield negative battery cable at battery. Tape the battery cable terminal to prevent accidental connection and air bag deployment.
2. After disconnecting negative battery cable, WAIT at least 2 minutes for reserve capacitor to discharge before servicing air bag system.

Activating System (Except Sebring Coupe & Stratus Coupe)

1. Connect DRB-III scan tool, or equivalent, to Data Link Connector (DLC). DLC is located on the driver side lower edge of the instrument panel, near steering column. Ensure latest version of DRB-III scan tool software cartridge is being used.
2. Turn ignition switch to ON position, with engine off. Exit vehicle with DRB-III scan tool. Ensure no one is inside vehicle, then reconnect negative battery cable.
3. Using DRB-III scan tool, read and record any active (current) or stored (historical) Diagnostic Trouble Codes (DTCs). Using DRB-III, erase all stored DTCs. If an problems exists, DTCs will not erase. If DTCs are found, perform diagnosis and repairs as necessary. If all DTCs are erased, go to next step.
4. From outside of the vehicle, and away from air bags, turn ignition off for about 15 seconds, then back to ON position. Observe AIR BAG warning light.
5. AIR BAG warning light should come on for about 6-8 seconds, then go out, indicating system is functioning properly. If AIR BAG warning light either fails to come on, blinks on and off, or comes on and stays on, a system malfunction exists. Diagnosis and repair air bag system as necessary.

Disabling System (Sebring Coupe & Stratus Coupe)

Turn ignition switch to OFF or LOCK position. Disconnect and shield negative battery cable at battery. WAIT at least 60 seconds for reserve capacitor to discharge before servicing air bag system. After disconnecting negative battery cable, tape the terminal to prevent accidental connection and air bag deployment.

Activating System (Sebring Coupe & Stratus Coupe)

1. Ensure ignition switch is in OFF or LOCK position. Reconnect negative battery cable. Turn ignition switch to ON position. SRS warning light should illuminate for 7 seconds and then go out, indicating system is functioning properly.
2. If AIR BAG warning light either fails to come on, blinks on and off, or comes on and stays on, a system malfunction exists. Diagnosis and repair air bag system as necessary.

SYSTEM OPERATION CHECK

1. When checking air bag system operation (also known as prove out system), and upon completion of each diagnostic test, check for faults in air bag system. To check system, turn ignition switch from OFF to RUN position. If AIR BAG warning light illuminates for approximately 6 seconds and then goes out, air bag system is functioning properly and no fault codes exist. NOTE: On regular cab and extra cab pickups, passenger air bag deactivation switch light must turn on and off in same manner as instrument cluster warning light during system operation check.
2. If a fault is detected in air bag system during initial system check, AIR BAG warning light will either fail to light, stay on continuously, or flash. Flashing may not begin for up to 30 seconds after initial bulb check (ignition turned from OFF to RUN). If AIR BAG warning light flashes, indicating a fault in system, diagnose and repair air bag system as necessary.
3. If a system fault exists and AIR BAG warning light fails to light, an audible tone will be heard, indicating AIR BAG warning light is out and service is required. The tone is a chime which sounds 5 sets of 5 beeps.

These precautions should be observed when working with SRS

1. Disable SRS before servicing any SRS or steering column components. Failure to do so may result in accidental air bag deployment and personal injury. See procedures under «DISABLING & ACTIVATING AIR BAG SYSTEM»(/buick/century/vi-1997-2005/remont/airbag/#supplemental-inflatable-restraint-system-deactivation-procedures) .
2. To deplete backup power supply energy, disconnect and isolate negative battery cable. WAIT at least one minute. Ensure that auxiliary batteries and other power supplies (if equipped) are disconnected.
3. On vehicles equipped with side air bags and seat belt pretensioners, manufacturer recommends removing front seats from vehicle before performing any diagnostics or repairs to seat air bag or seat belt pretensioner system. For diagnostics on systems other than side air bags or seat belt pretensioners, seats may be left in vehicle as long as simulator tool is installed in place of side air bag and seat belt pretensioner harness.
4. On all models, wait one minute after disconnecting negative battery cable before working on vehicle. Backup power supply holds a deployment charge for approximately one minute after negative battery cable is disconnected. Servicing SRS before one minute may cause accidental air bag deployment and possible personal injury.
5. To avoid accidental deployment and possible personal injury, the backup power supply must be depleted before repairing or replacing any front or side air bag Supplemental Restraint System (SRS) components and before servicing, replacing, adjusting or striking components near the front or side air bag sensors, such as doors, instrument panel, console, door latches, strikers, seats and hood latches.
6. Vehicle sensor orientation is critical for proper system operation. If a vehicle is involved in a collision, inspect sensor mounting bracket and wiring pigtail for deformation. If damaged, replace sensor.
7. After diagnosing or repairing a seat system or SRS, the air bag simulators must be removed before operating the vehicle over the road.
8. The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
9. Because of critical system operating requirements, DO NOT service air bag sensors, clockspring, diagnostic monitor or air bag module. Repairs are made by replacement only.
10. If replacing deployed air bag module, always install a NEW air bag Electronic Crash Sensor (ECS) module.
11. On vehicles with side air bags, use caution when working around "A", "B" and "C" pillars. Side air bag sensors are located at or near the base of the pillars.
12. Always wear safety glasses whenever servicing an air bag equipped vehicle or handling an air bag.
13. When carrying a live air bag module, ensure air bag module and trim cover are pointed away from your body. This minimizes chance of injury in event of an accidental deployment.
14. When placing a live air bag module on a bench or other surface, always face air bag module and trim cover facing up and away from surface. This will reduce motion of module if it is accidentally deployed.
15. After deployment, air bag surface may contain deposits of sodium hydroxide, which may irritate skin. Sodium hydroxide is a product of gas generant combustion. Always wear gloves and safety glasses when handling a deployed air bag. Wash your hands using mild soap and water. Follow correct disposal procedures.
16. Some models use 2 stage deployment inflators on driver and passenger air bag modules. If stage one was used to deploy a dual stage inflator module, stage 2 may still be active. Therefore, a deployed 2 stage air bag inflator module must be treated as an active module. When deactivating an air bag system with deployed air bags, a deployed 2 stage air bag may still be active. If disposal of a deployed or undeployed dual stage module is required, both deployment loops must be energized to deploy the air bag.
17. If scrapping a vehicle with an undeployed air bag module, air bag must be deployed.
18. If a part is replaced and new part does not correct condition, reinstall original part and perform diagnostic procedure again.
19. Never probe connectors on air bag module. Doing so may cause air bag deployment and/or personal injury.
20. Instruction to disconnect always refers to connector. DO NOT remove component from vehicle if instructed to disconnect.
21. After any servicing, ensure AIR BAG warning light does not indicate any fault codes. See «SYSTEM OPERATION CHECK»(/buick/century/vi-1997-2005/remont/airbag/#supplemental-inflatable-restraint-system-deactivation-procedures) .
22. Replace air bag module if trim cover (deployment doors) is marred or damaged. DO NOT repaint trim cover. Paint may degrade cover material. Replace air bag module as necessary. Ensure damaged air bag is deployed.
23. Clockspring electrical connectors are unique and cannot be reversed when connected to the driver air bag module. Match the electrical connector key to the keyway in the driver air bag module. DO NOT force electrical connectors into the driver air bag module.
24. Any time side safety curtain has deployed, the headliner, and all "A", "B" and "C" pillar trim panels and attaching hardware must be replaced along with any other damaged components and hardware. Failure to do so may result in personal injury in the event of a safety canopy deployment.

AIR BAG MODULE TORQUE SPECIFICATIONS (FORD)

GENERAL MOTORS

Pickups With Passenger Air Bag

Turn ignition switch from OFF to ON position. Turn passenger air bag switch to OFF position, then back to ON position. With ON/OFF switch in ON position, AIR BAG warning light should flash 7 times, then turn off.

The following AIR BAG warning light conditions indicate possible SIR system faults.

1. Light does not illuminate at all.
2. Light remains illuminated when ignition is turned on.
3. Light illuminates while vehicle is driven.

All Models Except Pickups With Passenger Air Bag

Turn ignition switch from OFF to ON or RUN position. AIR BAG warning light should flash 7 times (6-10 times on DeVille) and then turn off.

The following AIR BAG warning light conditions indicate possible SIR system faults.

1. Light does not illuminate at all.
2. Light remains illuminated when ignition is turned on.
3. Light illuminates while vehicle is driven.

SIR system faults are usually due to a disconnected/loose electrical connector caused by previous service on vehicle. Always check all Yellow SIR connectors for loose connections or damage.

If all connectors are okay, and AIR BAG warning light is still not operating properly, diagnose SIR system. Repair air bag system as necessary.

Vehicles With Passenger Presence System (PPS)

PASSENGER AIR BAG ON/OFF indicators located on the rear view mirror are used to notify the driver when the Passenger Presence System (PPS) has enabled or disabled the instrument panel inflator module. The PPS air bag indicators will also inform the driver of any PPS malfunctions. When the ignition is turned on, the PPS module is supplied with ignition 1 voltage and commands both PASSENGER AIR BAG ON/OFF indicators ON for 5 seconds. The PPS module conducts tests on the PPS components and circuits while both ON/OFF indicators are ON. If no malfunctions are detected, the PPS module will turn the PASSENGER AIR BAG indicator ON or OFF depending on the status of the PPS. If a malfunction is detected, the PPS module will store a Diagnostic Trouble Code (DTC), default the PPS to the OFF state and communicate with the SDM that a DTC has been set. When the SDM detects that the PPS has set a DTC, the SDM will set either DTC B0092 or B0098 and request the Instrument Panel Cluster (IPC) to turn the AIR BAG indicator located on the IPC ON. This is done to notify the driver of any PPS malfunctions. The presence of a SIR system malfunction could result in non-deployment of the air bags. The AIR BAG indicator will remain ON until the malfunction has been repaired.

Observe the following service precautions when working with air bag systems

1. Disable appropriate air bag system zone or zones before servicing any air bag system or steering column component. Failure to do this may result in accidental air bag deployment and possible personal injury. See «DISABLING & ACTIVATING AIR BAG SYSTEM»(/buick/century/vi-1997-2005/remont/airbag/#supplemental-inflatable-restraint-system-deactivation-procedures) .
2. Sensing and Diagnostic Module (SDM) maintains a reserve energy supply. Deployment power is available for as long as one minute after disconnecting battery power. Servicing vehicle before this time limit is reached may cause accidental air bag deployment and possible personal injury.
3. After repairs, stay well away from air bag inflator module(s), and turn ignition switch to ON position. Ensure AIR BAG warning light is working properly and no system faults are indicated. See «SYSTEM OPERATION CHECK»(/buick/century/vi-1997-2005/remont/airbag/#supplemental-inflatable-restraint-system-deactivation-procedures) .
4. Use only new, original equipment replacement parts. DO NOT use salvaged parts for SIR system repairs.
5. DO NOT expose air bag inflator modules to temperatures above 150°F (65°C).
6. Always wear safety glasses when servicing or handling an air bag.
7. Air bag module must be stored in its original special container until it is ready to be used for service. It must be stored in a clean, dry place, away from sources of extreme heat, sparks or high electrical energy.
8. When placing a live air bag module on a bench or other surface, always face air bag and trim cover upward, away from surface. This will reduce motion of module if it is accidentally deployed.
9. After deployment, air bag surface may contain deposits of sodium hydroxide which can irritate skin. Always wear safety glasses, rubber gloves and a long-sleeved shirt during clean-up. Wash hands using mild soap and water. Follow correct disposal procedures.
10. When carrying a live air bag module, point trim cover away from your body to minimize injury in case of accidental deployment. DO NOT carry live air bag module by wiring harness or connector.
11. DO NOT carry seat belt pretensioner by wiring harness or connector. Seat belt pretensioner can be carried by piston tube. When handling a live seat belt pretensioner, DO NOT touch seat belt pretensioner in cable area between buckle and mounting bolt hole. DO NOT cover pretensioner piston tube opening with hands or point open end at yourself or others.
12. Coil assembly must be replaced whenever air bag is deployed. Replace Sensing and Diagnostic Module (SDM), driver air bag module, passenger air bag module, side air bag module, side air bag sensor or front air bag sensor if any component has been dropped from a height of 3 feet or more.
13. DO NOT attempt to repair Sensing and Diagnostic Module (SDM), air bag inflator modules, air bag sensors or steering wheel coil assembly. Service all components by replacement only.
14. Electrical sources should never be allowed near inflator on back of air bag module.
15. Avoid touching Sensing and Diagnostic Module (SDM) terminals to prevent electrostatic discharge damage.
16. If water enters the vehicle's interior and soaks the carpet up to level of Sensing and Diagnostic Module (SDM), inspect the affected area and remove all evidence of water. Repair water damage, replace SDM, and replace harness connector. Failure to do this may result in accidental air bag deployment and possible personal injury.
17. If air bag system is not fully functional for any reason, vehicle should not be driven until system is repaired. DO NOT remove bulbs, modules, sensors or other components, or in any way disable system from operating normally. If air bag system is not functional, park vehicle until repairs can be made.

Note. When AIR BAG or SIR fuse is removed, and ignition is in ON position, AIR BAG warning light will illuminate. This is normal operation and does not indicate SIR system malfunction.

Supplemental Inflatable Restraint (SIR) Disabling & Enabling Zones

Note. Not all zones are used by all vehicles.

The Supplemental Inflatable Restraint (SIR) system has been divided into disabling and enabling zones. When performing service on or near SIR components or SIR wiring, it may be necessary to disable the SIR components in that zone. It may be necessary to disable more than one zone depending on the location of other SIR components and the area being serviced. (Scheme 20) Identify the specific zone or zones in which service will be performed and disable and enable selected zone or zones.

2. Turn ignition switch to RUN or ON position, with engine off. Exit vehicle with DRB-III scan tool. Ensure no one is inside vehicle.
3. Using DRB-III scan tool, read and record any active or stored Diagnostic Trouble Codes (DTCs). If DTCs are not active, erase all stored DTCs. If an active SRS problem exists, DTCs will not erase.
4. With ignition still on, check that nobody is in the vehicle. From outside of the vehicle, and away from air bags, turn ignition off for about 15 seconds, then back to the RUN or ON position.
5. Observe AIR BAG warning light. AIR BAG warning light should come on for about 6-8 seconds, then go out, indicating system is functioning properly. If AIR BAG warning light either fails to come on, blinks on and off, or comes on and stays on, a system malfunction exists. Diagnose and repair air bag system as necessary.

The following precautions should be observed when working with air bag systems

1. Disable air bag system before servicing any air bag system or steering column component. Failure to do this could result in accidental air bag deployment and possible personal injury. See «DISABLING & ACTIVATING AIR BAG SYSTEM»(/buick/century/vi-1997-2005/remont/airbag/#supplemental-inflatable-restraint-system-deactivation-procedures) .
2. Wait at least 2 minutes after disconnecting negative battery cable before servicing air bag system. Servicing air bag system before 2-minute period may cause accidental air bag deployment and possible personal injury.
3. DO NOT use any electrical test equipment on or near SRS components unless specified to do so. DO NOT use an analog ohmmeter. Use a DVOM with a maximum test current of 2 milliamps or less, at minimum resistance measurement range.
4. After deployment, air bag surface may contain sodium hydroxide deposits, which may irritate skin. Sodium hydroxide is a product of gas generant combustion. Always wear safety glasses, rubber gloves and a long-sleeved shirt during clean-up. Wash hands using mild soap and water. Follow correct disposal procedures.
5. Because of critical system operating requirements, DO NOT try to service any air bag components. Manufacturer recommends that defective components should always be replaced with only original equipment parts.
6. Deployed front air bags have 2 initiators (squibs) in the air bag inflator and may or may not have live pyrotechnic material within the inflator. DO NOT dispose of these air bags unless you are sure of complete deployment.
7. Factory installed fasteners have a special coating and are specifically designed for air bag components. Manufacturer recommends using original equipment replacement fasteners. DO NOT use substitutes.
8. Clockspring must be replaced if driver's air bag is deployed.
9. Each time a connector is disconnected, ensure it is clean and not damaged. Always pay particular attention to circuit being tested. Dirt, water and corrosion are the most common problems in connectors, causing voltage drop, open circuits and other improper operations.
10. When performing electrical tests, prevent accidental shorting of terminals. Such shorts can damage fuses or components and may cause a second fault code to set, making diagnosis of original problem more difficult.
11. After repairs are complete and ignition is turned to RUN or ON position, stay clear of air bag(s) to avoid injury in case of accidental air bag deployment.
12. When handling a seat belt tensioner retractor, proper care should be exercised to keep fingers out from under the retractor cover and away from seat belt webbing where it exits from the retractor cover.
13. Ensure air bag warning light is operating properly and system faults are not indicated. See «SYSTEM OPERATION CHECK»(/buick/century/vi-1997-2005/remont/airbag/#supplemental-inflatable-restraint-system-deactivation-procedures) .
14. When placing a undeployed (live) air bag on a bench or other surface, always face air bag and trim cover up, away from surface. This will reduce motion of module if accidentally deployed.
15. When carrying a undeployed (live) air bag module, point trim cover away from your body to minimize injury in case of accidental deployment.
16. Air bag module must be stored in its original special container until used for service. It must be stored in a clean, dry place, away from sources of extreme heat, sparks and electrical energy.
17. The Air Bag Control Module (ACM) contains an air bag sensor which enables SRS to deploy air bags. DO NOT connect ACM connector while battery is connected. Ensure ACM and mounting bracket are securely installed to vehicle before connecting electrical connector.
18. On vehicles equipped with side air bags or side curtain air bags, use caution when working around "B" pillar and/or side air bags.
19. Use extreme care to prevent any foreign material from entering air bag, or becoming entrapped between air bag cushion and air bag trim cover.
20. Never paint air bag trim covers or use a replacement trim cover not recommended by the manufacturer. Paint may change the way trim covers respond to an air bag deployment.
21. Electrical sources should never be allowed near connector on back of air bag module.
22. Passenger air bag module contains an Argon gas canister. Canister is pressurized to more than 2500 psi. DO NOT puncture, incinerate, or bring into contact with electricity. DO NOT store at temperatures above 200°F (93°C).
23. If SRS is not fully functional for any reason, vehicle should not be driven until system is repaired and functions properly. DO NOT remove bulbs, modules, sensors or other components, or in any way disable system from operating normally.

Activating System

Ensure ignition switch is in OFF or LOCK position. Connect negative battery cable. From a position clear of air bag(s), turn ignition switch to RUN or ON position. Observe SRS/AIR BAG warning light. Warning light should come on for 6-8 seconds and then go out, indicating system is functioning properly. If warning light fails to illuminate, or illuminates and stays on, a system malfunction exists. See SYSTEM OPERATION CHECK .
