What does this fault code mean?
The engine control module (ECM) has logged an internal fault in its own functions. The fault concerns the control module itself, not a sensor or wiring. Engine torque and speed may be limited. The fault may be permanent, or it may have occurred earlier and no longer be present.
Possible causes
- Damaged engine control module (ECM)
- Software in the engine control module is not the latest version
What you can do
- 1Read out and clear the code, road test the car and see whether it returns
- 2Have a workshop check that the engine control module has the latest software, since software is loaded with workshop equipment
- 3Check the battery and that its terminals are tight, since voltage disturbances can cause the fault
- 4If the fault remains after these checks, the engine control module is the likely cause and a workshop should replace it
Symptoms you may notice3
- Yellow warning symbol and message in the display
- The engine runs poorly or lacks power
- Malfunction indicator lamp (Check engine) lit or behaving abnormally
What the fault can affect2
- Engine torque may be limited
- Engine speed may be limited
General guidance for car owners. Diagnosis on the car can point to a different cause.
