What does this fault code mean?
The power steering control module has lost communication with the engine control module (ECM) on the CAN network. The fault lies in the engine control module, in the wiring, or in the control module that sends the information. The code is a knock-on fault and should stay stored until the faults in the CEM and any other affected modules are fixed. If the car is not a hybrid, the code can be ignored and cleared without further action.
Possible causes
- Fault in the control module that sends the information
- The fault lies in the engine control module (ECM)
- Short circuit between the CAN wiring
- Open circuit in the CAN wiring
What you can do
- 1If the car is not a hybrid: clear the code without further action and check that it does not come back
- 2If you have a diagnostic tool: look at the stored codes in the CEM and in the other modules, and fix those first
- 3Check that the cables do not run too close to sources of interference, such as mobile phones
- 4Check the connectors at the power steering and at the engine control module
- 5Safety note: steering is safety-critical, so have a workshop trace the CAN network if the power steering still performs poorly
Symptoms you may notice5
- Text window with warning symbol and yellow symbol and text message
- The power steering regulation does not work
- Abnormally high fuel consumption
- Steering requires extra or uneven effort
- The anti-spin function does not work
What the fault can affect1
- A predefined value is used in place of the real information
General guidance for car owners. Diagnosis on the car can point to a different cause.
