Clockspring Assembly / Spiral Cable: Procedures
Inflatable Restraint Steering Wheel Module Coil Centering
Notice: The new SIR coil assembly will be centered. Improper alignment of the SIR coil assembly may damage the unit, causing an inflatable
restraint malfunction.
Important: If double wire harness strap is installed onto the wire harness assembly and column, you must reuse the holder for the wire
straps during installation.
Remove the wire harness strap(s) where necessary.
1. 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 is in the LOCK position.
2. If the front (5) of the SIR coil has a centering window (4), and the back side (2) includes a spring service lock (1), perform the following steps:
1. Hold the SIR coil with the face up.
2. While depressing the spring service lock, rotate the coil hub clockwise until the coil ribbon stops.
3. Rotate the coil hub slowly, counterclockwise, until the centering window appears yellow and both arrows (3) line up.
4. Release spring service lock between the locking tab. The SIR coil is now centered.
5. Align the centered SIR coil with the horn tower and slide onto the steering shaft assembly.
3. If the front (4) of the SIR coil has a centering window (3), and the back side (1) includes NO spring service lock, perform the following steps:
1. Hold the SIR coil with the face up.
2. Rotate the coil hub clockwise until the coil ribbon stops.
3. Rotate the coil hub slowly, counterclockwise until the centering window appears yellow and both arrows (2) line up. This is the CENTER
position.
4. While holding the coil hub in the CENTER position, align the SIR coil with the horn tower and slide onto the steering shaft assembly.
