Express 1/2 Ton Van V8-5.7L VIN R (1999)
Clockspring Assembly / Spiral Cable: Description and Operation
The Inflatable Restraint Steering Wheel Module Coil consists of two or more current-carrying coils. The Inflatable Restraint Steering Wheel Module
Coil attaches 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.
There is a shorting bar on the yellow 2-way connector near the base of the steering column that connects the Inflatable Restraint Steering Wheel Module
Coil to the SIR wiring harness. The shorting bar shorts the circuits to the Inflatable Restraint Steering Wheel Module Coil and Inflatable Restraint
Steering Wheel Module during the disconnection of the yellow 2-way connector. The shorting of the Inflatable Restraint Steering Wheel Module Coil
and Inflatable Restraint Steering Wheel Module circuitry will help prevent unwanted deployment of the air bag when servicing the steering column or
other SIR system components.
