Alarm Module: Service and Repair
REMOVALWARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, DISABLE THE SUPPLEMENTAL RESTRAINT SYSTEM BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, DRIVER AIRBAG, PASSENGER AIRBAG, SEAT BELT TENSIONER, FRONT IMPACT SENSORS, SIDE CURTAIN AIRBAG, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE, THEN WAIT TWO MINUTES FOR THE SYSTEM CAPACITOR TO DISCHARGE BEFORE PERFORMING FURTHER DIAGNOSIS OR SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE SUPPLEMENTAL RESTRAINT SYSTEM. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.
1. Disconnect and isolate the battery negative cable.
2. If the vehicle is equipped with the optional tilt steering column, move the tilt steering column to the fully lowered position and leave the tilt release lever in the released (down) position.
Fig.11 Sentry Key Immobilizer Module Remove/Install:
3. From below the steering column, remove the two screws that secure the lower shroud to the upper shroud.
4. Using hand pressure, push gently inward on both sides of the upper shroud near the parting line between the upper and lower shrouds to release the snap features that secure the two halves to each other.
5. Remove both the upper and lower shrouds from the steering column.
6. Disconnect the instrument panel wire harness connector for the SKIM from the module connector receptacle.
7. The SKIM mounting bracket features a clip formation that secures the SKIM to the right lower flange of the steering column jacket. Pull downward on the connector end of the SKIM mounting bracket to release this clip from the steering column jacket.
8. Rotate the SKIM and its mounting bracket downwards and then to the side away from the steering column to slide the SKIM antenna ring from around the ignition switch lock cylinder housing. Lift the multi-function switch upward OFF of the upper steering column housing far enough to remove the SKIM antenna ring formation from between the ignition key release button and the multi-function switch housing.
9. Remove the SKIM from the steering column.
INSTALLATION
WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, DISABLE THE SUPPLEMENTAL RESTRAINT SYSTEM BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, DRIVER AIRBAG, PASSENGER AIRBAG, SEAT BELT TENSIONER, FRONT IMPACT SENSORS, SIDE CURTAIN AIRBAG, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE, THEN WAIT TWO MINUTES FOR THE SYSTEM CAPACITOR TO DISCHARGE BEFORE PERFORMING FURTHER DIAGNOSIS OR SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE SUPPLEMENTAL RESTRAINT SYSTEM. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.
1. Position the Sentry Key Immobilizer Module (SKIM) to the right side of the steering column. Lift the multi-function switch upward OFF of the upper steering column housing far enough to insert the SKIM antenna ring formation between the ignition key release button and the multi-function switch housing.
2. Slide the SKIM antenna ring around the ignition switch lock cylinder housing, then rotate the SKIM and its mounting bracket upwards and toward the steering column.
3. Align the SKIM mounting bracket clip formation with the right lower flange of the steering column jacket and, using hand pressure, push upward firmly and evenly on the connector end of the SKIM mounting bracket to engage this clip with the steering column jacket.
4. Reconnect the instrument panel wire harness connector for the SKIM to the module connector receptacle.
5. Position both the upper and lower shrouds onto the steering column.
6. Align the snap features on the lower shroud with the receptacles on the upper shroud and apply hand pressure to snap them together.
7. From below the steering column, install and tighten the two screws that secure the lower shroud to the upper shroud. Tighten the screws to 2 Nm (18 in. lbs.).
8. If the vehicle is equipped with the optional tilt steering column, move the tilt steering column to the fully raised position and secure it in place by moving the tilt release lever back to the locked (up) position.
9. Reconnect the battery negative cable.
NOTE: If the SKIM has been replaced with a new unit, the Sentry Key Immobilizer System (SKIS) MUST be initialized before the vehicle can be operated. (Refer to VEHICLE THEFT SECURITY - STANDARD PROCEDURE - SKIS INITIALIZATION).
