Wiring Diagram










DTC Will be Set When

The power source voltage to OCM is out of range (9 - 16 V) for specified time.

Flow Test Description

Step 2: Check if voltage on battery is within specified range.

Step 3: Check OCM power supply circuit.

Step 4: Check OCM ground circuit.

DTC Troubleshooting

1.
Was "Air Bag Diagnostic System Check" performed?
