Clockspring

The first step to replace the inflatable restraint steering wheel module air bag clock spring requires sir system deactivation. Start by removing the steering column trim covers before detaching the wire harness assembly from the wire harness strap to finally remove the wire harness straps from the assembly. Begin by removing the upper tilt head assembly wire harness strap then detach the sir steering wheel module air bag clock spring retaining clip and the sir steering wheel module air bag clock spring itself. Take the wave washer out from the upper shaft of the steering column. Put the block tooth of the upper shaft at 12 o'clock position before placing the wave washer on the upper shaft. The sir steering wheel module air bag clock spring needs centering because unsupported steering column movement or lower centering spring force can move the coil off position. Place the sir steering wheel module air bag clock spring in alignment with the horn tower on the turn signal cancel cam before installing this pre-centered coil onto the upper shaft. After discarding the centering tab users should gently tug the lower coil assembly wire to erase any kinks while confirming no bends interfere with the shaft lock system. Position the sir steering wheel module air bag clock spring retaining ring properly into the groove of the upper shaft before final installation. Pass the wire harness assembly by the steering column tilt head and keep it secure through the hole with a wire strap on the tilt head assembly. Secure wire harness straps to the assembly before replacing steering column trim covers and activating sir functionality.
