Was bedeutet der Fehlercode?
The CPM has registered that the signal from the heater fuel pump is too low, and the heater switches off when the code is set. The cause may be a short circuit to earth in the cable or a damaged fuel pump.
Mögliche Ursachen
- Short circuit to earth in the cable between the CPM and the fuel pump
- Damaged fuel pump
Was Sie tun können
- 1With a diagnostic tool, activate the fuel pump: no ticking sound means a probably permanent fault, while a pump that starts points to an intermittent one
- 2Disconnect the connector at the fuel pump and check the contacts for oxidation, looseness and poor connections
- 3Use a multimeter to check that the cable has no contact with earth (the body); if it does, the cable is shorted
- 4Clear the code and check that the heater starts after the repair
- 5If the fault returns, have a workshop check the fuel pump and the cable to the preheater module
Symptome, die Sie bemerken können2

Was der Fehler beeinflussen kann2
