Power Steering Control Module Communication Error
Power Steering Control Module can't communicate with the vehicle's system.
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 trying to send or receive messages but can't connect properly, which can lead to stiff steering or loss of assist.
What the computer is actually seeing
The system detects a communication failure with the Power Steering Control Module, meaning it can't establish a data link or the module isn't responding to requests within a set time frame.
What a healthy reading looks like
Expected response time is under 100 milliseconds for successful communication; voltage at the control module should be around 12V-14V when the ignition is ON.
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 the battery voltage; it should be between 12V-14V. If it's low, charge or replace it first.
- 22. Inspect wiring and connectors to the Power Steering Control Module for damage or corrosion. Repair as necessary.
- 33. Use a scan tool to check for additional codes. If other communication errors are present, address those first.
- 44. Clear the codes and perform a test drive to see if the code returns. If it does, replace the Power Steering Control Module.
Common causes
- Faulty Power Steering Control Module
- Damaged wiring or connectors
- Low battery voltage
- Corroded connectors

Frequently asked questions
Is it safe to drive with this code active?
It's moderately safe, but you may notice heavy steering and potential loss of assist, so drive with caution.
Will this problem come back after repairs?
If the root cause is not fixed, such as wiring issues, the code may return.
Why does this code pair with other communication codes?
Communication issues often stem from similar electrical failures, so they can appear together.
