Inflatable Restraint Steering Wheel Module Coil

The inflatable restraint steering wheel module coil consists of two or more coils that carry current. These coils are attached to the steering column. Two of the current-carrying coils allow rotation of the steering wheel and maintain 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 to the inflatable restraint steering wheel module when you disconnect the yellow 2-way connector. The circuits to the inflatable restraint steering wheel module short in order to prevent an unwanted deployment of the air bag when servicing the steering column or the SIR components.
