SPECIAL CARE DURING MECHANICAL REPAIRS
| WARNING | To avoid injury from accidental air bag deployment, read and carefully follow all SERVICE PRECAUTIONS and DISABLING & ACTIVATING AIR BAG SYSTEM procedures. |
| WARNING | Some vehicles are equipped with a passenger's side air bag ON/OFF switch. This switch should NOT be used in place of specified vehicle air bag system disabling and activating procedures. |
| WARNING | DO NOT use any type of back-up power supply (memory saver) from outside vehicle to avoid memory loss in memory systems, if equipped. Back-up power supplies can provide enough voltage to deploy air bags. |
Note. When the battery is disconnected, vehicle computer and memory system may lose data. Driveability problems may exist until computer systems have completed a relearn cycle.
In some instances, it may be necessary to remove steering column or instrument panel to gain access to blower motor housing, heater assembly, evaporator assembly, or other A/C-heater system related components. Observe manufacturer service precautions when working on a vehicle equipped with an air bag system. See SERVICE PRECAUTIONS .
Electrical sources should never be allowed near inflator on back of air bag module. Never probe air bag system electrical wires with analog volt-ohmmeter or test light. Always disable air bag system before servicing vehicle. See DISABLING & ACTIVATING AIR BAG SYSTEM . Failure to do so could 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 is again operational. 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 system is repaired and functions properly.
SYSTEM OPERATION CHECK
Turn ignition switch to ON or START position. SRS warning light should illuminate for about 7 seconds and then turn off and remain off for at least 5 seconds indicating that SRS system is operating properly. If SRS warning light does not illuminate as described, stays on for more than 7 seconds or illuminates while driving, SRS is malfunctioning and needs repair.
SERVICE PRECAUTIONS
Observe the following precautions when working with SRS
- Disable SRS before servicing any SRS or steering column component. Failure to do this may result in accidental air bag deployment and possible personal injury.
- WAIT at least ONE MINUTE after disabling air bag system before servicing vehicle. Air bag system maintains enough voltage to deploy air bags for ONE MINUTE after disconnecting battery.
- After servicing, check SRS warning light to verify system operation. See «SYSTEM OPERATION CHECK»(/mitsubishi/lancer-evolution/viii-2003-2005/remont/restraints/#air-bag-deactivation-procedures__system-operation-check) .
- Always wear safety glasses when servicing or handling an air bag.
- Battery posts, terminals and related accessories contain lead and lead compounds. WASH HANDS after handling to reduce lead exposure.
- DO NOT expose SRS-ECU, air bag module and clockspring to temperatures greater than 200°F (93°C).
- DO NOT expose seat belt with pretensioner to temperatures greater than 194°F (90°C).
- SRS components and seat belt pretensioner should not be subjected to heat. Remove SRS-ECU, driver's and front passenger's air bag modules, clockspring, side-air bag modules, and seat belt pretensioners before drying or baking vehicle after painting.
- When placing a live air bag module on a bench or other surface, always face air bag module and trim cover up, away from surface. This will reduce motion of module if air bag accidentally deploys.
- To prevent damage to driver's air bag clockspring, center front wheels before removing steering wheel or steering gear. Center front wheels and align clockspring neutral marks before installing steering wheel.
- After air bag deploys, air bag surface may contain deposits of sodium hydroxide, which irritates skin. Always wear safety glasses, rubber gloves and long-sleeved shirt during clean-up. Wash hands using mild soap and water. Follow correct clean-up and disposal procedures.
- Because of critical system operating requirements, DO NOT service or repair any SRS components, including wiring harness. Repairs are only made by replacing defective component(s).
- DO NOT allow any electrical source near inflator on the back of air bag module. DO NOT use an ohmmeter or powered circuit tester on air bag modules.
- When carrying a live (undeployed) air bag module, trim cover must be pointed away from body to minimize injury in case of accidental air bag deployment.
- Make certain ignition switch is in the LOCK (OFF) position when scan tool is connected or disconnected.
- DO NOT probe a wire through insulator, as this will damage wire and eventually cause failure due to corrosion.
- If SRS is not fully functional for any reason, DO NOT drive vehicle until system is repaired and is fully functional. DO NOT remove bulbs, modules, sensors or other components, or in any way disable system from operating normally. If SRS is not functional, park vehicle until repairs are made.
DISABLING & ACTIVATING AIR BAG SYSTEM
To disable system, turn ignition switch to LOCK (OFF) position. Disconnect and isolate negative battery cable. WAIT at least ONE MINUTE before servicing vehicle. To activate system, ensure ignition switch is in LOCK position and reconnect negative battery cable. Staying well away from air bag modules, turn ignition switch to ON position. Ensure AIR BAG indicator light operates properly. See SYSTEM OPERATION CHECK .
