B00DF — Passenger Airbag Disable Switch Circuit Fault

Severity: medium Safe to drive

What B00DF means

The airbag (SRS) control module monitors the switch that turns the front passenger airbag on or off, for example when a child seat is used. B00DF sets when the switch signal or circuit resistance is outside the expected range, which points to an open, short, poor connection or a faulty switch. The module may then not know whether the airbag is enabled.

Symptoms

  • Airbag or SRS warning light on
  • Passenger airbag off indicator on or behaving oddly
  • Switch does not change the indicator state
  • Restraint system warning messages in the cluster

Possible causes

  1. Faulty passenger airbag disable switch
  2. Open, short or poor connection in the switch circuit
  3. Corroded or partly unseated connector
  4. Damaged wiring or harness behind the dash
  5. Faulty SRS control module
  6. Instrument cluster or electrical fault

How to diagnose

  1. Scan for codes with an SRS-capable tool and note any seat occupancy or airbag codes
  2. Operate the switch and see whether the indicator changes
  3. Inspect the switch and connector for dirt, corrosion and bent pins
  4. Check the harness from the switch to the SRS module for chafing or breaks
  5. Measure circuit resistance and voltage per the factory wiring diagram, after disconnecting the battery and waiting the specified time
  6. Verify power and ground at the switch
  7. Clear the code and confirm it does not return
  8. If the circuit is good, test the SRS module and instrument cluster

Common fixes

  • Replace the passenger airbag disable switch
  • Repair the switch wiring or connector
  • Replace and code the SRS module if confirmed faulty
  • Repair the instrument cluster and reprogram it if needed

Questions and answers

What does B00DF mean?

The SRS module detected a fault in the passenger airbag disable switch circuit. The switch, its connector or wiring is the usual culprit.

Can I drive with B00DF?

Yes, but the passenger airbag may not work or be disabled correctly. Fix it soon, especially if passengers or children ride in front.

How do I clear B00DF?

Repair the cause first, then clear the code with a scan tool that supports SRS. If the fault remains, the code and warning light will come back.

This is general information about the code. The meaning can differ between makes and models: a scan tool and the repair manual for your car will show the exact cause.
