Airbag Steering Wheel Module Coil Centering
- 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.
Inspect the steering wheel airbag coil. If the yellow lock pin (1) is present, the uplead post (2) is at the 12 o'clock position and the loop (u-turn) appears in the centering window (3) then the coil is already in the centered position and no further action is required.
If the steering wheel airbag coil needs to be centered, perform the following preliminary steps:
- Ensure the wheels on the vehicle are straight ahead.
- Ensure the block tooth (1) on the steering shaft is in the 6 o'clock position.
To center the steering wheel airbag coil, perform the following steps:
- Hold the coil with the face up.
- Slowly rotate the coil hub clockwise until the coil ribbon stops.
- Slowly rotate the coil hub counterclockwise approximately 2.5 turns until the uplead post (1) is at the 12 o'clock position.
- View the centering window (2) and ensure the loop (u-turn) is visible. If the loop is visible then the coil is in the center position.
- While holding the coil hub in the center position, align the coil with the steering column components and slide the coil onto the steering shaft.
