Co oznacza ten kod błędu?
The combustion preheater module (CPM) measures the resistance across the coolant diverter valve for the auxiliary heater. The code is set when the valve has an electrical fault, here a short to earth. The heater's function is then blocked.
Możliwe przyczyny
- Damaged cable to the distribution valve
- Damaged connector
- Distribution valve shorted to earth
- Damaged distribution valve
Co możesz zrobić
- 1Check the cable to the diverter valve visually for any damage
- 2Check that the connector at the diverter valve is secure and free from oxidation
- 3Use a multimeter to check that the cable has no contact with the body (earth); if it does, the cable is shorted
- 4Clear the code and start the heater again to see whether the fault returns
- 5If the fault is not fixed, have a workshop replace the diverter valve
