Hva betyr feilkoden?
Information about the vehicle's power supply is stored in the central electronic module (CEM) and in the battery monitoring sensor (BMS). The fault shows that the car's standby current is too high when the battery is already at low voltage, which can drain the battery further. The check runs once an hour.
Mulige årsaker
- A control module does not go into standby
- A control module has an internal short circuit
- Leakage current in wiring or connectors somewhere in the car
Hva du kan gjøre
- 1Charge the battery and check that it holds its voltage while the car is parked
- 2Clear the code and check whether it returns after the car has been left locked overnight
- 3Check that the battery terminal clamps are tight and clean
- 4Remove extra equipment fitted afterwards, such as an alarm or charger, and see whether the fault clears
- 5If the fault returns, have a workshop measure the standby current and find which control module or circuit draws too much
Symptomer du kan merke4
- The engine does not start
- No clicking sound when trying to start
- The battery is dead or has low voltage
- The central locking does not work
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
