Sentry Key Immobilizer Module: Notes
WARNING: This page is about a different car, the 2002 Jeep Grand Cherokee. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
On vehicles equipped with air bags, disable the supplemental restraint system before attempting any steering wheel, steering column, driver airbag, passenger airbag, front impact sensor, side impact sensor, side curtain airbag, or instrument panel component diagnosis or service. Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the supplemental restraint system. Failure to take the proper precautions could result in accidental airbag deployment and possible personal injury.
