Check Wiring Between Control Module & Passenger Impact Sensor

Check the Wiring Harness Between the Control Module and the Passengers Side Impact Sensor












- Turn the ignition switch to the OFF position.

Unplug the connector.
- Impact sensor, passenger door, front (328P)
- Check pins 1 and 2 for open circuit/pin slid-out and rectify if necessary.

Unplug the connector.
- Control module, Airbag (331)
- Check pins 43 and 44 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

- 43 - Control module, Airbag
- 2 - Impact sensor, passenger door, front

The reading should be 0 Ohm - 2 Ohm

Checking the wiring harness.
Jiggle the leads and in-line connectors at several places and in different directions to reveal intermittent breaks and short circuits in the wiring harness. Observe the multimeter; test lamp or diagnostic tool while doing this.

Is the function correct?

NO - Rectifying the Lead

YES - Continue with Check the Wiring Harness Between the Control Module and the Passengers Side Impact Sensor












Measure the resistance. The value should be infinite.

- 43 - Control module, Airbag
- B -
