Airbag Deployment Command Circuit Low
The airbag system detected a low voltage in the deployment command 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)
Inside the airbag control module, there are signals that determine when to deploy the airbags during a crash. If the voltage in the circuit that's supposed to send the deployment command is too low (below 0.5 volts when it should be over 3 volts), the system triggers this code.
What the computer is actually seeing
The airbag control module monitors the resistance and voltage levels in the deployment command circuit. It should see a voltage above 3 volts when the circuit is functioning correctly. If it drops below 0.5 volts, it sets this fault code.
What a healthy reading looks like
Deployment command signal voltage should be between 3 to 5 volts during normal operation.
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 module connectors for damage or corrosion. If damaged, repair/replace.
- 22. Check the wiring between the airbag control module and the deployment circuit for continuity using a multimeter. Resistance should be less than 5 ohms. If resistance is high or broken, repair the wiring.
- 33. Measure the voltage at the deployment command circuit while turning the ignition on but the engine off. It should be between 3 to 5 volts. If it's below 0.5 volts, repair the circuit or replace the airbag control module.
Common causes
- Damaged wiring or connectors in the airbag circuit
- Faulty airbag control module
- Previous deployment of airbags causing circuit fault
Typical repair cost

Frequently asked questions
Is it safe to drive with this code?
No, it's not safe as the airbags may not deploy in an accident.
Will this code come back after clearing it?
Yes, if the underlying issue isn't fixed, the code will return.
Why does this code pair with airbag codes?
Because they all relate to the airbag system's deployment functionality.
