Test 2A: Driver Squib Circuit Open (Active Code)
NOTE:
Perform TEST VER-1A: AIR BAG VERIFICATION TEST
after all repairs. Each time a connector is disconnected, inspect it to ensure it is in good condition. Always focus on circuit being tested. Dirt, water and corrosion, are most common problems in connectors.
- Ensure ignition is off. Disconnect battery and wait 2 minutes before proceeding. Disconnect driver-side air bag module. Connect fused jumper wire between driver-side air mag module squib connector terminals No. 1 (Dark Green-Light Blue wire) and No. 2 Black-Light Blue wire). See Fig 1 . Turn ignition on, then reconnect battery. Using DRB, read active codes. If DRB displays DRIVER SQUIB CIRCUIT SHORTED, replace driver-side air bag module. If DRB does not display DRIVER SQUIB CIRCUIT SHORTED, go to next step.
- Disconnect battery and wait 2 minutes before proceeding. Disconnect clockspring 2-pin connector. Connect fused jumper wire between Black-Light Blue and Dark Green-Light Blue wires of clockspring 2-pin connector. See WIRING DIAGRAMS . Turn ignition on, then reconnect battery. Using DRB, read active codes. If DRB does not display DRIVER SQUIB CIRCUIT SHORTED, remove jumper wire and go to next step. If DRB displays DRIVER SQUIB CIRCUIT SHORTED, replace clockspring.
- Disconnect battery and wait 2 minutes before proceeding. Remove any jumper wires previously installed. Disconnect ACM harness connector. Measure resistance of Black-Light Blue wire between ACM harness connector terminal No. 2 and clockspring 2-pin connector. See Figure . If resistance is less than 5 ohms, go to next step. If resistance is more than 5 ohms, repair open or high resistance in Black-Light Blue wire. See WIRING DIAGRAMS ..
- Measure resistance of Dark Green-Light Blue wire between ACM harness connector terminal No. 1 and clockspring 2-pin connector. If resistance is less than 5 ohms and there are no potential causes remaining, replace ACM. If resistance is more than 5 ohms, repair open or high resistance in Dark Green-Light Blue wire.
