Supplemental Inflatable Restraint System - Deactivation Procedures Cadillac CTS I

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.

SYSTEM OPERATION CHECK

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

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.

Note. When the following conditions apply: Air Bag lamp is on. Passenger Air Bag indicator always reads off. DTC B0092 is reported. The cause of this condition may be a shorted Passenger Presence System (PPS) sensor wire. The PPS sensor harness is located under the front passenger seat. This harness may be pinched between the seat frame and the track/riser.

SERVICE PRECAUTIONS

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»(/cadillac/cts/i-2002-2007/remont/restraints/#supplemental-inflatable-restraint-system-deactivation-procedures__disabling-activating-air-bag-system) .
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»(/cadillac/cts/i-2002-2007/remont/restraints/#supplemental-inflatable-restraint-system-deactivation-procedures__system-operation-check) .
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 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 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 SDM terminals to prevent electrostatic discharge damage.
16. If water enters the vehicle's interior and soaks the carpet up to level of 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.

DISABLING & ACTIVATING AIR BAG SYSTEM

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 DISABLING & ENABLING ZONES
