Fault Code 35 Passenger Airbag Low Resistance or Shorted

FAULT CODE 35
Passenger Side Airbag Circuit Low Resistance or Shorted


Normal Operation
The Air Bag Diagnostic Module (DM) monitors the resistance between pins 8 and 9. The value of this resistance is normally between 0.9 Ohm and 1.2 Ohm. If the resistance measured is less than 0.7 Ohm the MIL Lamp will illuminate and fault code 35 will be present, indicating low resistance or short circuit on the airbag circuit.

Possible Causes
- Shorting between DM pins 8 and 9, passenger-side airbag not installed.
- Poor connection of airbag harness.
- Faulty airbag harness connector.
- Short circuit in airbag harness.
- Short circuit across passenger-side airbag terminals.

Fault Diagnosis
1. Circuit-check
- Disarm the Airbag/SRS system and disconnect the passenger-side airbag.
- Disconnect the DM and remove the plastic locking wedge from the black harness connector.
- Measure resistance across harness connections to passenger-side airbag, wires RP and KR
- Does resistance indicate open circuit?

Yes - Proceed to step 2.
No - Inspect harness wiring, cable reel cassettes and terminals for short circuit. repair as necessary.

2. Code verification
- Install airbag simulator in place of passenger-side airbag module.
- Re-connect DM.
- Switch on the ignition and wait 30 seconds.
- Is code 35 still present?

Yes - Renew DM.
No -

- Examine shorting bar on driver-side airbag connector for correct operation, repair if necessary.
- Renew airbag module if shorting bar is operating correctly.

3. On completion
- Arm and verify the Airbag/SRS system.
