Diagnostic Procedure

1. Disable air bag system. See DISABLING SYSTEM under DISABLING & ACTIVATING AIR BAG SYSTEM.

2. Measure resistance between ground and spiral cable side of upper spiral cable connector Yellow/Black wire (circuit D+). See WIRING DIAGRAMS . If resistance is more than one megohm, go to next step. If resistance is less than one megohm, go to step 5 .

3. Reconnect air bag sensor assembly connector A20 (center connector). Connect jumper wire between upper spiral cable connector Yellow/Black wire (circuit D+) and Yellow wire (circuit D-). Connect negative battery cable. Wait at least 2 seconds. Turn ignition switch to ON position. Wait at least 20 seconds. Clear DTCs. See CLEARING CODES under DIAGNOSTICS. Turn ignition switch to LOCK position. Wait at least 20 seconds. Turn ignition switch to ON position. Wait at least 20 seconds. Retrieve DTCs. See RETRIEVING CODES under DIAGNOSTICS. If DTC 11/B0102 is displayed, replace air bag sensor assembly. If DTC 11/B0102 is not displayed, go to next step.

4. Turn ignition switch to LOCK position. Disconnect negative battery cable. Wait at least 90 seconds. Reconnect upper spiral cable connector (to driver-side air bag module). Reconnect negative battery cable. Wait at least 2 seconds. Turn ignition switch to ON position. Wait at least 20 seconds. Clear DTCs. See CLEARING CODES under DIAGNOSTICS. Turn ignition switch to LOCK position. Wait at least 20 seconds. Turn ignition switch to ON position. Wait at least 20 seconds. Retrieve codes. See RETRIEVING CODES under DIAGNOSTICS. If DTC 11/B0102 is displayed, replace driver-side air bag module. If DTC 11/B0102 is not displayed, system is functioning properly at this time. Check for intermittent fault. See AIR BAG WARNING LIGHT INTERMITTENT .

5. Disconnect spiral cable lower connector. Measure resistance between ground and spiral cable side of upper spiral cable connector Yellow/Black wire (circuit D+). If resistance is more than one megohm, go to next step. If resistance is less than one megohm, replace spiral cable.

6. Measure resistance between ground and air bag sensor assembly side of lower spiral cable connector Yellow/Black wire (circuit D+). If resistance is less than one megohm, replace wiring harness between spiral cable and air bag sensor assembly. If resistance is more than one megohm, system is functioning properly at this time. Check for intermittent fault. See AIR BAG WARNING LIGHT INTERMITTENT .
