Was bedeutet der Fehlercode?

This code concerns the L signal from the generator, which is either too high, missing or shows a regulator fault. The fault is intermittent, so it has occurred before but may not be present right now. The generator may then stop charging and the battery discharges.

Mögliche Ursachen

The generator is not charging because it lacks an energy source
A faulty central electronic module
A diode fault in the generator

Was Sie tun können

1Switch the ignition on and check that the charging warning lamp lights. It should go out when the engine starts
2Check that the battery terminals and the ground connection are clean and tight
3Check that the generator drive belt is intact and tensioned correctly, and not slipping
4If you have a diagnostic tool, follow the battery voltage in live data with the engine running. The fault may be intermittent
5After the work, clear the code and check that the charging warning does not light again

Symptome, die Sie bemerken können4

The charging lamp lights while the engine is running
The warning lamp does not light when the ignition is switched on
The battery discharges
