What it means
A control module has detected that the software in the steering angle sensor module is incompatible with its own software or configuration. Steering-related assistance or stability functions may be affected; the specific effects depend on the vehicle.
How it works
The steering angle sensor module reports steering-wheel position to systems such as stability control and electric steering assistance. This code sets when another module finds the sensor module’s software or configuration incompatible with its own, so steering-related assistance or stability functions may be limited.
Common causes
Most likely first.
- Incorrect or incompatible steering angle sensor module software
- Module replacement without required programming or configuration
- Incorrect module part number
Symptoms
- Multiple warning lights may illuminate
- Affected modules may go into limp mode or shut down
- Specific functions inoperative depending on module
- Diagnostic tools may show communication faults
How to diagnose it
- Scan the steering, stability-control, and other modules; save freeze-frame data and related configuration or communication codes.
- Check whether the fault appeared after steering-angle sensor module replacement, steering work, or a software update.
- Read the sensor module’s identification and software version, and compare them with vehicle-specific service information.
- Inspect the sensor module’s connectors and network wiring for damage, corrosion, or loose terminals.
- If the module communicates correctly, verify its configuration and any required steering-angle setup using the manufacturer’s procedure.
Common fixes
- Repair a loose or corroded steering-angle sensor module connection.
- Complete required steering-angle setup or module configuration.
- Program compatible software into the sensor module.
- Replace an incorrect-part-number sensor module with a compatible unit and program it as required.
Can I keep driving?
If steering assistance or stability warnings appear, drive cautiously and avoid high speeds, slippery roads, and sudden maneuvers until the fault is diagnosed. Stop if steering effort or control changes unexpectedly, since assistance or stability functions may be reduced.
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.
