Left Front Side Airbag Deployment Command Circuit Low
The circuit for the left front side airbag has a low voltage issue.
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 computer is detecting a problem where the voltage in the circuit that controls the left front side airbag is too low, which could prevent the airbag from deploying properly in a crash.
What the computer is actually seeing
The airbag control module expects a voltage in the range of 1.5V to 12V when the system is armed. A voltage reading below this indicates a fault in the deployment circuit.
What a healthy reading looks like
Normal voltage is expected to be between 1.5V and 12V; anything lower is considered 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. Inspect the left front side airbag circuit for visible damage or corrosion.
- 22. Check the connector at the airbag module for any loose pins or corrosion; clean and reseat if necessary.
- 33. Measure the voltage at the airbag connector while the ignition is on; expect 1.5V to 12V.
- 4 - If voltage is below 1.5V, troubleshoot the wiring back to the airbag control module.
- 54. If wiring is good, scan the vehicle for additional codes related to the airbag system and address those first.
- 65. If all else checks out, replace the airbag module.
Common causes
- Damaged wiring in the airbag circuit
- Faulty airbag module
- Corroded connectors
- Accident damage to the door or body structure
- Faulty airbag sensor
