What it means
The variable effort steering control module checks whether the installed component is compatible with the system. It sets this code when it detects an incorrect or mismatched component.
At a glance
- Usually lights the ABS or stability-control warning light
- The engine or gearbox may go into limp mode
How it works
The variable-effort steering control module checks whether the installed module or component matches the vehicle's system configuration. This code sets when the detected component is incompatible, incorrectly configured, or incompletely programmed.
Common causes
Most likely first.
- Incorrect replacement component
- Incompatible steering control module
- Component not configured for the vehicle
- Incorrect or incomplete module programming
Symptoms
- ABS warning light on
- ESC/stability control deactivated
- Possible reduced brake assist
- Speedometer may behave erratically
How to diagnose it
- Record freeze-frame data and scan the steering and ABS systems for configuration, communication, or related component codes.
- Identify any recently replaced steering module or component and compare its vehicle application and configuration with the manufacturer's parts and service information.
- Inspect module connectors and wiring for damage or poor seating that could prevent component identification.
- Use the appropriate scan tool to read module identification and configuration, then compare it with the vehicle's required setup.
- Verify that programming and calibration procedures specified for the installed component were completed.
- If the component and configuration are correct, diagnose module communication and compatibility using the manufacturer's procedure.
Common fixes
- Secure module connectors and repair any wiring fault affecting identification or communication.
- Configure or program the installed component for the vehicle using the specified procedure.
- Complete required calibration after programming.
- Replace an incorrect or incompatible component with the correct application.
- Replace the control module if it is confirmed to be the wrong or faulty unit.
Can I keep driving?
Stability control or other steering-related assistance may be unavailable, and brake assist may be reduced. Drive cautiously only if steering and braking feel normal, and have an incorrectly configured system corrected promptly.
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.
