Was bedeutet der Fehlercode?
The CPM has registered that the signal on the heater fuel pump cable is too high. The cause may be a short circuit to supply voltage in the cable or a damaged fuel pump. The heater cannot be started until the code has been cleared.
Mögliche Ursachen
- Live-voltage short in the wire running from the CPM to the fuel pump
- Damaged fuel pump
Was Sie tun können
- 1Clear the code and start the heater again; if the code returns, the fault is still present
- 2If you have a diagnostic tool, activate the fuel pump and listen for a ticking sound; if it does not start, the fault is probably permanent
- 3Disconnect the connector at the fuel pump and check that the contacts are tight and free from oxidation
- 4Use a multimeter to check that the fuel pump cable carries no voltage when the heater is off; if it does, the cable is shorted to positive
- 5If the fault returns, have a workshop check the fuel pump and the wiring to the preheater module
Symptome, die Sie bemerken können2
