WARNING: This page is about a different car, the 2017 Jeep Cherokee. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
To avoid serious or fatal injury on vehicles equipped with airbags, disable the Supplemental Restraint System (SRS) before attempting any steering wheel, steering column, airbag, Occupant Classification System (OCS), seat belt tensioner, impact sensor 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 SRS. Failure to follow these instructions may result in accidental airbag deployment.
- Install and tighten the screw (1) that secures the BCM to the mounting brackets. Tighten the screw to the proper torque. Refer to TECHNICAL SPECIFICATIONS .
- Position the BCM with mounting brackets to the instrument panel support structure outboard of the steering column as a unit and connect the wire harness connectors (1) to the back of the BCM.
- Install and tighten the screws (1) that secure the BCM and BCM mounting bracket to the instrument panel support structure. Tighten the screws to the proper torque. Refer to TECHNICAL SPECIFICATIONS .
- Connect the wire harness connectors to the BCM.

- Install the steering column opening cover to the instrument panel. Refer to COVER, STEERING COLUMN OPENING, INSTALLATION .
- Connect the negative battery cable. If equipped with an Intelligent Battery Sensor (IBS), connect the IBS connector to the negative battery cable.
- Using the scan tool, perform the "IBS calibration" routine. If this is not completed, the Electronic STOP/START (ESS) function will not operate.
- If this Electronic Control Unit (ECU) is being replaced with a new unit, a diagnostic scan tool MUST be used to align the PROXI configuration data into the new ECU. Follow the routine outlined in the diagnostic scan tool for PROXI Configuration Alignment under Body Control Module (BCM) Miscellaneous Functions menu.
