Co oznacza ten kod błędu?
The four-wheel drive control module (DEM) checks whether the signal to the control valve is reasonable by comparing the current with predefined limits. The code is stored when the current falls outside them with the engine running. This can be caused by a signal wire shorted to ground or by a broken supply, and the four-wheel drive is then disengaged.
Możliwe przyczyny
- Signal wire shorted to ground
- Break in the voltage supply
Co możesz zrobić
- 1Read and erase the code, then road test to see whether it returns
- 2Check that the fuses are intact
- 3Check the connectors and wires to the control valve for damage, chafing and loose contacts
- 4Use a multimeter to check that the signal wire has no contact with ground (the body) when disconnected, and that it is intact
- 5If the code returns, have a workshop with diagnostic equipment check and replace the control valve or the control module if needed
