Removal And Installation: Installation
To avoid serious or fatal injury on vehicles equipped with airbags, disable the Supplemental Restraint System (SRS) before attempting any steering wheel, steering column, airbags, airbag curtains, knee blocker, seat belt tensioner, impact sensor or instrument panel component diagnosis or service. Disconnect the Intelligent Battery Sensor (IBS)/negative battery cable assembly from the negative battery post, 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 take the proper precautions could result in accidental airbag deployment.
Always turn the steering wheel until the front wheels are in the straight-ahead position. Then, prior to disconnecting the steering column from the steering gear, lock the steering wheel to the steering column. If clockspring centering has been compromised for ANY reason, the entire Steering Column Control Module (SCCM) and clockspring unit MUST be replaced with a new unit.
A service replacement SCCM is shipped with the clockspring pre-centered and with a molded plastic locking pin installed. This locking pin should not be removed until the SCCM has been installed on the steering column.
- Position the SCCM (3) onto the top of the steering column jacket.
- Tighten the screw (1) that tensions the band clamp that secures the SCCM to the top of the steering column jacket. Tighten the screw securely.
- Connect the instrument panel wire harness connectors (2) to the connector receptacles on the back of the SCCM housing near the top and the bottom.
- Install the upper and lower shrouds onto the steering column. Refer to SHROUD, STEERING COLUMN, REMOVAL AND INSTALLATION .
- Move the steering column to the fully raised (up) position.
- If a new SCCM is being used, break off the plastic locking pin that secures the clockspring rotor to the SCCM housing to maintain clockspring centering.
- Install the steering wheel onto the steering column. Refer to WHEEL, STEERING, REMOVAL AND INSTALLATION .
- Connect the negative battery cable. If equipped with an Intelligent Battery Sensor (IBS), connect the IBS connector.
If this Electronic Control Unit (ECU) is being replaced with a new unit, a diagnostic scan tool MUST be used to determine if alignment of the PROXI configuration data into the new ECU is needed. If PROXI alignment is needed, follow the routine outlined in the diagnostic scan tool for PROXI Configuration Alignment under the Body Control Module (BCM) Miscellaneous Functions menu.
