Invalid Data from Restraint Control Module
The Restraint Control Module detected invalid data from the airbag sensor 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 car's computer is seeing something wrong with the airbag sensor data, which could mean a problem with the sensor itself or its connections.
What the computer is actually seeing
The Restraint Control Module (RCM) is receiving unexpected voltage levels from the airbag sensors, which might be too high or too low; typically, you would expect around 2.5 volts on a properly functioning sensor.
What a healthy reading looks like
Expected voltage from the airbag sensor circuits should be between 1.0 to 4.5 volts, with a specific average around 2.5 volts. Any large deviation can set this code.
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 system fuses. Replace any blown fuses and recheck the code.
- 22. Inspect the wiring and connectors both at the airbag sensors and the RCM; look for fraying, corrosion, or loose connections. Repair any damage found.
- 33. Use a multimeter to measure the voltage at the airbag sensors. Ensure it falls between 1.0 and 4.5 volts. If readings are out of range, check the sensor itself.
- 44. If the sensor appears good, connect a scan tool and check for additional codes related to the airbag system that might help pinpoint the issue.
- 55. If all other checks pass, consider replacing the airbag sensor or the RCM depending on which is faulty. Clear the codes and test drive.
Common causes
- Faulty airbag sensor
- Open or shorted wiring in the airbag circuit
- Poor connector mating or corrosion
- Faulty Restraint Control Module (RCM)
- Incorrectly installed components after repairs
