Removal and Installation

MODULE-STEERING CONTROL

REMOVAL

WARNING: To avoid personal injury or death, on vehicles equipped with airbags, disable the supplemental restraint system before attempting any steering wheel, steering column, airbag, occupant classification system, 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 supplemental restraint system. Failure to take the proper precautions could result in accidental airbag deployment.

CAUTION: A service replacement Steering Control Module (SCM) is shipped with the clockspring pre-centered and with a molded plastic locking pin installed. This locking pin should not be removed until the SCM has been installed on the steering column. If the locking pin is removed before the SCM is installed on a steering column, the clockspring centering procedure must be performed.

NOTE: Before starting this procedure, be certain to turn the steering wheel until the front wheels are in the straight-ahead position and that the entire steering system is locked or inhibited from rotation.

CAUTION: All fasteners must be torqued to specification to ensure proper operation of the steering column.

1. Position the front wheels straight-ahead.
2. Disconnect and isolate the negative (ground) cable from the battery.

WARNING: Wait two minutes for the airbag system reserve capacitor to discharge before performing further diagnosis or service.

3. Remove the driver airbag.





4. Remove the steering wheel retaining bolt (4), then slide the steering wheel (3) off the shaft (5).





Remove the steering column shrouds (1 & 2).





5. Disconnect the two electrical connectors (3 & 4) to the SCM (2).





6. Remove the two screws (1) retaining the SCM (3) to the column shaft (2).
7. Pull the SCM (3) off the steering column shaft (2).

INSTALLATION

WARNING: If the clockspring, which is integral to the Steering Control Module (SCM) is not properly centered in relation to the steering wheel, steering shaft and steering gear, it may be damaged. Service replacement clocksprings are shipped pre-centered and with a locking pin installed. This locking pin should not be removed until the clockspring has been installed on the steering column. If the locking pin is removed before the clockspring is installed on a steering column, the clockspring centering procedure must be performed.

NOTE: Before starting this procedure, be certain that the front wheels are still in the straight-ahead position.





1. Install the SCM onto the steering column.





2. Tighten the two screws (1) securing the SCM (3) to the column shaft housing.





3. Connect the two electrical connectors (3 & 4) to the SCM (2)





4. Install the steering column shrouds (1 & 2).





5. Align the spline on the steering wheel hub to shaft (5) and install the steering wheel (3).
6. Install a NEW retaining bolt (4). Torque the bolt to 61 Nm (45 ft. lbs.).
7. Install the driver airbag.
8. Connect the battery negative cable.

NOTE: IF EQUIPPED WITH ESP - recalibrate the steering angle sensor using the scan tool.
