Was bedeutet der Fehlercode?

The central electronic module (CEM) monitors the battery voltage and has found it too high for a while with the engine running. The cause may be a damaged generator or a damaged battery. The fault is stored with the engine running, once the high voltage has lasted long enough.

Mögliche Ursachen

Damaged generator (GEN)
Damaged battery

Was Sie tun können

1Check the battery: if it is swollen, leaking or will not hold its charge, it should be replaced
2If you have a diagnostic tool, read battery voltage in live data with the engine running and check that it is steady and does not climb over time
3Have a workshop check the generator and the charge regulator, since a faulty generator can supply too high a voltage
4If the fault returns after the battery has been checked, have a workshop check the charging system

Symptome, die Sie bemerken können5

The battery discharges
The generator warning lamp comes on with the engine running
A red warning symbol and a text message appear
The battery seems to be dead
The engine does not start
