Bravada V6-4.3L VIN W (1997)
SIR Coil Assembly: Description and Operation
The inflatable restraint steering wheel module coil consists of two coils which carry currents. These coils are attached to the steering column. The coils
allow rotation of the steering wheel. They also maintain continuous contact between the deployment loop and the inflatable restraint steering wheel
inflator module.
A shorting bar is located on the yellow 2-way connector at the base of the steering column. The shorting bar connects the inflatable restraint steering
wheel module coil to the SIR wiring harness. The shoring bar shorts the circuits to the inflatable restraint steering wheel module coil and the inflator
module when the 2-way connector is disconnected. This helps prevent unwanted deployment of the air bag while servicing the steering column or other
SIR components.
