Module, Steering Column Control (SCCM): Installation

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, 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 take the proper precautions could result in accidental airbag deployment.

CAUTION:

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.

Before reinstalling the Steering Column Control Module (SCCM) onto the steering column, the clockspring centering must be confirmed by viewing the inspection window (3) on the clockspring rotor (1). If the black squares (2) on the internal clockspring tape are not visible through the inspection window, the clockspring centering has been compromised and the SCCM MUST be replaced.
Make sure the front wheels are still in the straight ahead position.
If a new SCCM is being installed, disengage the steering column gap hider from the lower edge of the old SCCM shroud and transfer it to the new one.
Position the SCCM close enough to the top of the steering column to reach through the back of the gap hider and shroud and connect the instrument panel wiring harness connector to the lower SCCM.

Align the hub of the SCCM with the upper steering column shaft (5) and jacket (3).
Slide the SCCM over the top of the steering column jacket, far enough for the spring-loaded upper and lower keystones (6) to engage the slots (4) in the top and bottom of the steering column jacket.
Confirm that the keystones are fully engaged in the column jacket slots by inspecting the round red indicator (7) visible on the lower surface of the SCCM shroud. The indicator should be flush with the shroud. If the indicator is not flush with the shroud, the keystones are NOT fully engaged. Carefully slide the SCCM slightly up and down, or rotate it slightly right and left, as necessary, to allow the keystones to snap into their slots and the indicator to become flush with the shroud.

NOTE:
The SCCM wiring harness MUST be pulled back out of the SCCM shroud and secured to the instrument panel base trim. Failure to properly perform this task can result in unsatisfactory buzzes, squeaks or rattles during vehicle operation.
Pull the gap hider bezel up and away from the instrument panel, far enough to access and engage the wiring harness retainer clip (2) to the instrument panel base trim (1) on the right side of the steering column opening.
Align and engage the retainers securing the molded hard plastic steering column gap hider bezel to the instrument panel.
If a new SCCM is being installed, remove (break off) the red locking tab that secures the clockspring rotor to the clockspring case.
Install the steering wheel onto the upper steering column shaft. Make sure to align and insert the rotational lugs on the steering wheel hub into the slots in the hub of the clockspring. Also, the steering wheel fastener MUST be tightened to the proper torque specification for proper clockspring and Steering Angle Sensor (SAS) operation. Refer to WHEEL, STEERING, INSTALLATION .
Connect the steering wheel wiring harness connectors to the upper SCCM.
Install the Driver Air Bag (DAB). Refer to AIR BAG, DRIVER, INSTALLATION .
Connect the negative battery cable. If equipped with an Intelligent Battery Sensor (IBS), connect the IBS connector.
