Description
DESCRIPTION
The clockspring is mounted to the steering column behind the steering wheel. This assembly consists of a flat, ribbon like, electrically conductive tape that winds and unwinds with the steering wheel rotation. The clockspring is used to maintain a continuous electrical circuit between the wiring harness and the:
- Driver Airbag
- Headlamp Dimmer Switch
- Horn Switch
- Left Multi-Function Switch (Exterior/Interior Lamp Control)
- Right Multi-Function Switch (Wiper Control)
- Speed Control Switch
The left and right multi-function switches attach to the clockspring and is then mounted to the steering column as an assembly.
The clockspring is part of the Steering Column Control Module (SCCM). The SCCM is secured near the top of the steering column below the steering wheel. The SCCM is a modular unit that also interfaces with and supports the left (lighting) multi-function switch and the right (wiper) multi-function switch. Each of these switches and the clockspring can be separated from and are serviced individually from the SCCM.
Within the plastic case is a spool-like molded plastic rotor with a large exposed hub. The upper surface of the rotor hub has a large, keyed center hole, an index hole, two short pigtail wires with connectors, and one connector receptacle that face toward the steering wheel. Wound around the rotor spool within the case 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 receptacles that face 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. The lower surface of the rotor hub has a molded plastic turn signal cancel cam with two lobes that is keyed to the clockspring rotor.
The service replacement clockspring is shipped with the clockspring pre-centered and with a molded plastic locking pin installed. The locking pin secures the centered clockspring rotor during shipment and handling, but must be removed after the SCCM is installed on the steering column and after the steering wheel is installed Service and Repair.
The clockspring cannot be repaired. If the clockspring is faulty, damaged, or if the driver airbag has been deployed, the clockspring must be replaced. Removal.
