Passenger Airbag Disable Switch Circuit Failure
This code indicates a failure in the passenger airbag disable switch circuit.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The passenger airbag disable switch is supposed to turn off the airbag when there is no passenger, but it can't, possibly due to wiring problems or a bad switch.
What the computer is actually seeing
The airbag control module detects an abnormal voltage level or a faulty signal from the passenger airbag switch. Typically, it should see the switch provide a specific voltage level, usually around 5V when active.
What a healthy reading looks like
Switch should output between 0.5V to 4.5V when toggled between enabled and disabled states.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 11. Inspect the airbag disable switch and its wiring for visible damage.
- 22. Check for corrosion on the connector, clean if necessary, and ensure connections are secure.
- 33. Use a multimeter to measure voltage at the switch; verify it outputs 0.5V to 4.5V when toggled.
- 44. If voltage is out of specification, replace the airbag disable switch.
- 55. If voltage is okay, check the integrity of the wiring back to the airbag control module.
- 66. If wiring is good, perform a scan for additional codes, and consider testing the airbag control module.
Common causes
- Faulty airbag disable switch
- Damaged wiring or connectors
- Corrosion in the connector
- Faulty airbag control module
