WARNING: To service any component of the SCCM, the entire assembly must be removed from the column. This must be done due to the clockspring passing through the assembly and into the self docking connector. Failure to remove the assembly could damage the pins of the clockspring and prevent the airbag system from operating properly.

The clockspring assembly is secured with three screws (1) onto the top of the Steering Column Control Module (SCCM). Refer to DESCRIPTION near the top of the steering column behind the steering wheel.

The clockspring consists of a flat, round molded plastic case. Within the plastic case is a spool-like molded plastic rotor with a hub. The surface of the rotor hub has a large center hole. Within the plastic case and wound around the rotor spool is a long ribbon-like tape that consists of several thin copper wire leads sandwiched between two thin plastic membranes. The outer end of the tape terminates at the connector terminals that align themselves into the SCCM self-docking connector that faces the instrument panel, while the inner end of the tape terminates at the pigtail wires and connector receptacles on the hub of the clockspring rotor that face the steering wheel.

Service replacement clocksprings are shipped pre-centered and with the screws backed out and holding the clockspring into place. If reusing a clockspring or installing a new one that you are unsure if it is centered or not, see STANDARD PROCEDURE .

The clockspring cannot be repaired. If the clockspring is faulty, damaged, or if the driver airbag has been deployed, the clockspring must be replaced.
