What it means
A chassis control module checks its stored vehicle identification number against the VIN expected by the vehicle’s configuration. It sets this code when the VIN is missing or incompatible.
How it works
A chassis control module stores a vehicle identification number and checks it against the VIN expected for the vehicle's configuration. This code sets when the stored VIN is missing or does not match, including when an incorrect VIN was entered after module replacement.
Common causes
Most likely first.
- VIN not programmed after module replacement
- Incorrect VIN stored in the module
Symptoms
- ABS warning light on
- Traction or stability control warning light on
- ABS functions may be limited
How to diagnose it
- Scan the chassis control module and read its stored VIN and configuration information.
- Compare the module's VIN with the VIN on the vehicle and the expected configuration data.
- Review repair history for a module replacement or programming event that could have left the VIN blank or incorrect.
- Verify that the installed chassis control module is compatible with the vehicle.
- If the module is compatible, correct its VIN or configuration using the manufacturer's approved programming procedure, then rescan.
Common fixes
- Program the correct vehicle VIN into the module.
- Correct the module's vehicle configuration using the approved procedure.
- Replace an incompatible module with the correct unit and program it for the vehicle.
Can I keep driving?
ABS, traction, or stability assistance may be limited while the module reports this fault. Drive cautiously and leave extra stopping distance until the module is correctly configured.
A code shows where the control module detected a fault, not always which part failed. Check the causes in order and confirm with a test before replacing parts. Have several codes? Check them together
This is a generic code: it means the same on every make. The car’s maker may add more detail in its own service information.
