Inflatable Restraint Steering Wheel Module Coil Centering
WARNING: This page is about a different car, the 2011 Cadillac DTS. However, it is still accessible from the selected car via links, so may be relevant.
- Verify the following conditions before centering the SIR coil:
- The wheels on the vehicle are straight ahead.
- The block tooth (1) of the steering shaft assembly is in the 12 o'clock position.
- The ignition switch assembly is in the LOCK position.
- Hold the coil with the face up.
- Rotate the coil hub in the direction of the arrow (1) until the coil ribbon stops.
- Rotate the coil hub, slowly, counterclockwise, for 2 1/2 revolutions. This is the CENTER position.
- While maintaining the coil hub in the CENTER position, align the centered coil with the horn tower and slide the coil onto the steering shaft assembly.
CAUTION:
The new SIR coil assembly will be centered. Improper alignment of the SIR coil assembly may damage the unit, causing an inflatable restraint malfunction.
