Was bedeutet der Fehlercode?

The CPM has logged a supply voltage that stayed too low for some time, and this sets the code. The cause may be a poorly charged battery, poor contact at the module connections or a blown fuse. The heater cannot be activated until the code has been cleared.

Mögliche Ursachen

Poorly charged battery
Contact resistance in the module connections
Blown fuse

Was Sie tun können

1Check the battery: charge it if needed and check that the terminals are tight and clean
2Replace the fuse feeding the CPM with a new one if it has blown
3Check that the connectors at the CPM are secure and free from oxidation
4If you have a diagnostic tool, read battery voltage in live data as the heater starts and see whether it drops sharply
5Clear the code and start the heater again; if nothing is found, it may have been a temporary fault

Symptome, die Sie bemerken können3

Poor heating in the passenger compartment
The parking heater does not work
An information lamp is lit
