WARNING: This page is about a different car, the 2003 Jeep Liberty. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
ON VEHICLES EQUIPPED WITH AIR-BAGS, 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. REFER TO AIR BAG RESTRAINT SYSTEMS

NOTE:
Before replacing a Body Control Module (BCM), use a DRBIII(R) scan tool to retrieve the current settings for the BCM programmable features and the axle ratio/tire size (electronic pinion factor). Refer to the appropriate diagnostic information. These settings should be duplicated in the replacement BCM using the DRBIII(R) scan tool before returning the vehicle to service.
- If the vehicle is equipped with the optional Remote Keyless Entry (RKE) system, reinstall the RKE module into the BCM. (Refer to POWER LOCKS ).
- Position the BCM onto the Junction Block (JB) (Figure ).
- Install and tighten the screws that secure the BCM to the JB. Tighten the screws to 2 N.m (18 in. lbs.).
- Reinstall the Junction Block Module (JBM) onto the instrument panel end bracket on the driver side of the vehicle. (Refer to POWER DISTRIBUTION ).
- Reconnect the battery, negative cable.
