9-3 (9400) FaultTrace Mode

Check the wiring harness between the control module and the driver's side impact sensor

Turn the ignition switch to the OFF position.

Unplug the connector:

Impact sensor, driver's door 328D

• Check pins 1 and 2 for open circuit/pin slid-out and rectify if necessary.

Unplug the connector:

Control module, Airbag 331

• Check pins 41 and 42 for open circuit/pin slid-out and rectify if necessary.

• Connect the break-out box (BOB) to the wiring harness.

Take a resistance reading between

• 42 Control module, Airbag

• 2 Impact sensor, driver's door

• Move the wiring harness at several spots and in several directions to reveal intermittent breaks and short-circuits. Check switches, connectors and crimp connections for oxidation, retracted pins and pin clamping force.

The reading should be 0 - 2 Ohm

Is the function correct?
