Clockspring Assembly / Spiral Cable: Description and Operation

The inflatable restraint steering wheel module coil consists of two or more current-carrying coils. These coils are attached to the steering column. Two of the current-carrying coils allow rotation of the steering wheel while maintaining continuous contact of the driver deployment loop to the inflatable restraint steering wheel module.

A shorting bar is placed on the yellow 2-way connector near the base of the steering column. This connector joins the SIR coil to the SIR wiring harness. The shorting bar shorts the circuits to the SIR coil and the inflatable restraint steering wheel module whenever you disconnect the yellow 2-way connector. The circuit to the inflatable restraint steering wheel module is shorted in this way in order to help prevent an unwanted deployment of the air bag when servicing the steering column or other SIR system components.
