Steering Control Module Malfunction
There’s a problem with the steering control module.
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 steering control module is not working right, which can affect how your steering system operates.
What the computer is actually seeing
The steering control module is not sending or receiving expected signals. Typically, this module communicates with sensors to monitor and adjust the steering assist based on vehicle speed and steering angle.
What a healthy reading looks like
Steering module should operate with voltage around 5V on signal wires, and the CAN bus should have valid messages every 10-20ms while steering is active.
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.
- 1Check the vehicle's wiring and connectors to the steering control module for any visible damage or corrosion.
- 2Verify power and ground to the steering control module. You should see around 12V on power and 0V on ground in a good circuit.
- 3Use a scan tool to check for additional codes and freeze frame data for any anomalies in steering input and output values.
- 4Inspect the steering position sensor and ensure it’s functioning within its specified voltage range, typically around 0.5-4.5V at rest and during movement.
Common causes
- Faulty steering control module
- Wiring issues or bad connectors
- Loss of power or ground to the module
- Intermittent faults in the CAN bus communications.

Frequently asked questions
Can I drive the vehicle with this code active?
Yes, it may still be drivable but steering assist could be compromised, so drive with caution.
Will this code come back after clearing?
It might if the underlying issue isn't fixed, like a wiring problem or a bad module.
Does this fault relate to any other systems?
Yes, it's often linked to the vehicle's stability and traction control systems.
