- Disable air bag system. See DISABLING & ACTIVATING AIR BAG SYSTEM. Disconnect front impact sensor connectors (center, left, and right), and measure resistance of each sensor. See Figure . Resistance should be approximately 1.2 k/ohms. If resistance is not as specified, replace sensor and go to step 5).
- If resistance is about 1.2 k/ohms, reconnect all front impact sensor connectors. Disconnect diagnostic module Black and Gray connectors. See Figure or Figure . Measure resistance between diagnostic module Gray connector Brown/Green wire and ground. If resistance is 1.2 k/ohms, go to next step. If resistance is not 1.2 k/ohms, replace wire harness.
- Measure resistance between diagnostic module Gray connector Brown/Red wire and ground. If resistance is 1.2 k/ohms, go to next step. If resistance is not 1.2 k/ohms, replace wire harness.
- Measure resistance between diagnostic module Black connector Brown/Black wire and ground. If resistance is 1.2 k/ohms, go to next step. If resistance is not 1.2 k/ohms, replace wire harness and go to next step.
- If disconnected, reconnect diagnostic module and clockspring connectors. Reconnect negative battery cable. Turn ignition switch to ON position and check warning light operation. If warning light flashes 10 times, replace diagnostic module.
