What does this fault code mean?
The engine control module (ECM) compares the fuel pump status received over CAN with the signal it sends to the pump. The fault is set when the pump keeps running even though the control module has switched it off. The fault is first registered in the central electronic module (CEM), so that module should be checked first.
Possible causes
- Signal wire shorted to voltage
- Damaged fuel pump
What you can do
- 1Read the codes in the central electronic module (CEM) first and deal with them
- 2The code in the engine control module can only be cleared once the CEM fault has been fixed and cleared
- 3Check that the fuses for the fuel pump are intact. Fuse locations are shown in the owner's manual
- 4Use a multimeter to check that the signal wire to the pump is not shorted to positive
- 5Look at the fuel pump connector for chafing and loose connections
- 6If the fault remains, have a workshop check the fuel pump and how it is controlled with diagnostic equipment
