This code indicates that the vehicle's network has detected a software version mismatch or incompatibility with the Restraints Control Module (RCM), which manages the airbag system. It typically occurs after a module replacement without proper programming, or if an over-the-air or diagnostic software update was interrupted.
A used or new RCM was installed but not flashed or initialized with the correct software calibration for the specific vehicle.
A previous attempt to update the RCM software was interrupted or failed, leaving the module with incompatible or corrupted firmware.
Battery voltage dropped during a module flash or self-update, corrupting the software installation process.
Wiring or network issues are corrupting the data signals, causing the system to misinterpret the module's software version.
The internal memory of the RCM has physically failed, preventing it from holding or executing the correct software.
No, it is not recommended. A software incompatibility in the restraints module means the airbags may not deploy correctly, or at all, in a crash.
No, replacing the Restraints Control Module or PCM is almost never the correct fix for this code. It is a software issue, so the existing module typically just needs to be reprogrammed or flashed with the correct calibration.
Some vehicles attempt module self-configurations or updates upon power restoration. If battery voltage is insufficient during this process, the software update can fail, triggering this incompatibility code.
No, generic scan tools can only read and clear basic codes. Reprogramming the RCM requires an advanced, OEM-level diagnostic tool capable of flashing new software to the module.
