IGNITION LOCK CYLINDER REPLACEMENT - ON VEHICLE
CAUTION:This vehicle is equipped with a Supplemental Inflatable Restraint (SIR) System. Failure to follow the correct procedure could cause the following conditions:
Air bag deployment
Unnecessary SIR system repairs
In order to avoid the above conditions, observe the following
Refer to COMPONENT LOCATIONS in order to determine if you are performing service on or near the SIR components or the SIR wiring.
If you are performing service on or near the SIR components or
the SIR wiring, disable the SIR system. Refer to DISABLING & ACTIVATING AIR BAG SYSTEM.
1. Disable SIR system.
2. Remove the 3 screws and the steering column lower trim cover (6).
4. Remove the one screw and the steering column upper trim cover (7).

5. Insert the ignition key into the ignition lock cylinder (8).
6. Turn the key to the ACC position.
7. Use a screwdriver to push in the stop pin on the underside of the lock cylinder case (7).
8. Remove the ignition lock cylinder (8) from the ignition lock cylinder case (7).
Fig. 25: Inserting Ignition Key Into Ignition Lock Cylinder
1. Insert the ignition key into the ignition lock cylinder (8). Ensure that the key is in the ACC position.
2. Insert the ignition lock cylinder (8) into the ignition lock cylinder case (7) until the stop pin engages.
3. Remove the key from the ignition lock cylinder.
4. Install the steering column upper trim cover (7). Secure with 1 screw.
5. Install the steering column lower trim cover (6). Secure with 3 screws.
6. Enable the SIR system.
DISABLING & ACTIVATING AIR BAG SYSTEM
CAUTION:Vehicle computer and memory systems may loose memory data when battery is disconnected. Driveability problems may result. Vehicle computer may need to complete relearn cycle.
Accidental air bag deployment is possible. Personal injury may
result. Read and follow service precautions. See AIR BAG SAFETY
1. Turn steering wheel to place vehicle wheels in straight-ahead position. Remove key from ignition. Remove IGN fuse and CIG fuse from fuse block, located in lower left instrument panel, behind storage box cover.
2. Remove lower steering column cover. Release, unlock and disconnect SIR coil Yellow 2-pin connector. See Fig. 1. Remove glove box. Release, unlock and disconnect passenger-side air bag Yellow 2-pin connector. See Fig. 2.
3. Release, unlock and disconnect driver and passenger side impact air bag module connectors, located under driver and front passenger seats.

Fig. 2: Locating Passenger-side Air Bag Yellow 2-pin Connector
1. Remove key from ignition. Connect and lock driver and passenger side impact air bag module connectors, located under driver and front passenger seats.
2. Connect and lock passenger-side air bag module Yellow 2-pin connector. See Fig. 2. Install glove box. Connect and lock SIR coil Yellow 2-pin connector. See Fig. 1. Install lower steering column cover.
3. Install IGN and CIG fuses in fuse block. Check system for proper operation. See SYSTEM OPERATION CHECK.
AIR BAG SAFETY PRECAUTIONS
Observe these precautions when servicing the air bag system:
SDM maintains sufficient voltage to cause air bag or seat belt pretensioner deployment for up to one minute after ignition is turned off, battery is disconnected or fuse powering SDM is removed. Disable AIR system before working on vehicle.
After repairs, ensure AIR BAG warning light is working properly and no system faults are indicated. See SYSTEM OPERATION CHECK.
Always wear safety glasses when servicing or handling an air bag module or seat belt pretensioner.
Air bag modules must be stored in original special containers until used for service. Store in a clean, dry place, away from sources of extreme heat, sparks or high electrical energy.
Air bag modules or SDM should not be subjected to temperatures greater than 150 F (65 C).
SIR components should not be used if they have been dropped from a height of 3 feet (0.9 m) or greater.
When placing a live air bag module on a bench or other surface, always make certain that trim cover faces up. This will reduce motion of module if accidentally deployed.
After deployment, air bag surface may contain deposits of sodium hydroxide, which can irritate skin. Always wear safety glasses, rubber gloves and long-sleeved shirt during clean-up. Wash hands using mild soap and water. Follow correct disposal procedures.
At no time should any electrical source be allowed near inflator on back of air bag module.
DO NOT apply power to SIR system unless all components are connected or a diagnostic test requests it, as this will set a Diagnostic Trouble Code (DTC).
When carrying a live air bag module, trim cover should be pointed away from body to minimize injury in case of accidental deployment.
DO NOT attempt to service any SIR component. All defective SIR components must be replaced.
DO NOT probe a wire through insulator. Wire will be damaged and eventually fail due to corrosion.
When performing electrical tests, prevent accidental shorting of terminals. Such mistakes can damage fuses or components and may cause a second fault code to set, making diagnosis of original problem more difficult.
When using diagnostic tests to diagnose SIR system, under no circumstances should a volt/ohmmeter, test light or any type of electrical equipment not specified by manufacturer be used.
If SIR 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.
SYSTEM OPERATION CHECK
AIR BAG warning light should come on for about 6 seconds and then turn off when ignition is first turned on. System malfunction is indicated when light fails to function as described.
