Test 3A - Driver Squib Circuit Open
NOTE:
Perform TEST VER-1A - 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. Due to manufacturer changes in wire colors, use terminal identification whenever possible.
- Disconnect battery and wait 2 minutes before proceeding. Disconnect driver-side air bag module. Connect a jumper wire between driver-side air bag module squib connector terminals. Turn ignition on and reconnect battery. Go to next step.
- 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 clockspring 2-pin connector. Connect a jumper wire between clockspring 2-pin connector terminals. Using DRB, read active codes. If DRB displays DRIVER SQUIB CIRCUIT SHORTED, replace clockspring. If DRB does not display DRIVER SQUIB CIRCUIT SHORTED, go to next step.
- Disconnect battery and wait 2 minutes before proceeding. Remove jumper wire. Disconnect ACM 4-pin connector. Using an ohmmeter, check resistance between ACM 4-pin connector terminal No. 3 (Dark Green/Light Blue wire) and clockspring 2-pin connector terminal No. 1 (Dark Green/Light Blue wire). If resistance is more than one ohm, repair open or high resistance in Dark Green/Light Blue wire. If resistance is less than one ohm, go to next step.
- Using an ohmmeter, check resistance between ACM 4-pin connector terminal No. 4 (Black/Light Blue wire) and clockspring 2-pin connector terminal No. 2 (Black/Light Blue wire). If resistance is more than one ohm, repair open or high resistance in Black/Light Blue wire. If resistance is less than one ohm, replace ACM.
