Passenger Airbag Status Indicator Circuit Low
This code means the airbag passenger status indicator circuit is too low.
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 status light isn't getting enough voltage signal, which means it might not show if the airbag is on or off properly.
What the computer is actually seeing
The Body Control Module (BCM) checks for voltage levels on the passenger airbag status indicator circuit. It expects to see between 5V and 12V when the circuit is active. If the voltage drops below 4.5V, it triggers code B004E.
What a healthy reading looks like
5V to 12V on the indicator circuit when active; less than 4.5V indicates a fault.
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. Start by checking the airbag status indicator light. Does it illuminate when the ignition is on? If no, check the bulb and wiring to it.
- 22. Inspect the wiring harness and connectors for damage or corrosion. Repair or replace as necessary.
- 33. Measure the voltage at the airbag status indicator circuit with a multimeter. Is it between 5V and 12V? If yes, the circuit is functioning properly; consider testing the BCM. If no, proceed to the next step.
- 44. Check the ground connection for the BCM and the airbag indicator circuit. Is it secure and free of corrosion? Fix any grounding issues found.
- 55. If all wiring checks out, replace the airbag indicator light if it doesn’t light up or show the proper signal.
Common causes
- Faulty airbag indicator light
- Damaged wiring or connectors
- Failed Body Control Module (BCM)
- Poor ground connection to BCM
