Power Steering Control Module - Internal Failure
The power steering control module has detected an internal fault.
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 power steering control module is like the brain for your steering assistance. If it has a problem, it can't help you steer properly, making it harder to turn the wheel.
What the computer is actually seeing
The power steering control module monitors its own internal processes and if it finds errors in the communication or sensor readings it generates this fault code.
What a healthy reading looks like
Expected operational voltages for the power steering system are between 9 and 16 volts, with normal current draw around 2-5 amps when 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.
- 11. Check power steering fluid level. Should be at the proper mark. If low, top off and retest. If fluid is fine, proceed to next step.
- 22. Inspect wiring and connectors at the power steering control module. Look for corrosion, loose connections, or damage. Repair or clean as necessary, then retest.
- 33. Measure voltage at the power steering control module while the vehicle is on. It should read 9-16 volts. If outside this range, troubleshoot power supply issues. If voltage is okay, proceed to next step.
- 44. Run a self-diagnostic with a scan tool on the power steering control module. If it shows internal fault codes again, the module likely needs replacement.
Common causes
- Faulty power steering control module
- Wiring or connector issues
- Low power steering fluid level
- Battery voltage issues

Frequently asked questions
Is it safe to drive with this code?
It may be harder to steer, making driving unsafe. Fix it ASAP.
Will the code come back if I clear it?
If the internal issue in the control module isn't fixed, it will return.
Why does this code appear after replacing the steering pump?
If the pump replacement caused a voltage issue or if the module itself was already faulty, the code can appear regardless of the pump being new.
