Was bedeutet der Fehlercode?
The fault code is set when the heater control module registers too high a signal on the cable to the fuel pump. This points to the cable being short-circuited to battery voltage, or to a damaged pump. The heater cannot be started until the fault code has been erased.
Mögliche Ursachen
- The cable between the heater control module and the fuel pump is short-circuited to battery voltage
- Damaged fuel pump
Was Sie tun können
- 1With the ignition off, check the cables and connectors between the heater and the fuel pump for damage, chafing and corrosion.
- 2Disconnect the fuel pump connector and check that the contacts are clean and free from looseness or oxidation.
- 3With the ignition off, use a multimeter: voltage on the pump cable means a short to positive, which must be repaired.
- 4If you have a diagnostic tool: activate the fuel pump and listen for it to start. If it does not start, the fault is still present.
- 5Replace the fuel pump if it is damaged, or have a workshop do it.
- 6If the fault remains after checking the wiring, have a workshop check the heater control module.
