Co oznacza ten kod błędu?
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.
Możliwe przyczyny
- Damaged generator (GEN)
- Damaged battery
Co możesz zrobić
- 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
Objawy, które możesz zauważyć5
- 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
