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.

1. Verify the following conditions before centering the SIR coil:
* The wheels on the vehicle are straight ahead.
* The block tooth and the centering mark (1) of the steering shaft assembly is in the 12 o'clock position.





2. If available, remove the yellow retaining tab (1) from the SIR coil and save the tab for reassembly.
3. Hold the SIR coil face up by the casing (2).
1. Slowly turn the coil hub (3) clockwise until the coil ribbon stops.
2. Slowly rotate the coil hub (3) counterclockwise 2.5 revolutions until the centering window (4) turns yellow. This indicates the CENTER position.

Important: If the retaining tab is not available, the use of tape to secure the coil is recommended for installation to the steering column.

4. Install the yellow retaining tab (1) to the SIR coil.
5. Slide the centered SIR coil onto the steering shaft assembly.
