Co oznacza ten kod błędu?
The heater control module has found an electrical fault on the fuel pump, for example a short to battery voltage or an open circuit. The heater's function is blocked, and the heating in the cabin can be poor. The fault is often a loose or corroded connector or damaged wiring.
Możliwe przyczyny
- Contact resistance and oxidation in the connections
- Open circuit in the wiring
- Wiring short-circuited to battery voltage
Co możesz zrobić
- 1Check that the fuse for the auxiliary heater is intact.
- 2With the ignition off, check the connectors and wiring to the fuel pump for corrosion, looseness and damage.
- 3Use a multimeter to check that the wiring to the fuel pump is not broken and has no battery voltage when the ignition is off.
- 4If you have a diagnostic tool: activate the fuel pump and listen for it to start. If it does not start, the fault is probably still present.
- 5If the heater works during a test drive, the fault may be intermittent. Then check the connectors and wiring again after a few drives.
- 6If the fault remains after checking the wiring, have a workshop with diagnostic equipment investigate further.
