Co oznacza ten kod błędu?
The high voltage battery charger consists of the battery charger control module (OBC) and an OBC Gateway, which talk to each other over an internal sensor CAN. The fault is set when communication between the control module and the charger is missing, while the cable is plugged in and its switch is turned on. Charging the high voltage battery is not possible while the fault remains.
Możliwe przyczyny
- Open circuit in the CAN cables between the battery charger control module (OBC) and the OBC Gateway
- Short circuit in the CAN cables between the battery charger control module (OBC) and the OBC Gateway
- Contact resistance, oxidation or poor contact in the connections
- The charging cable is damaged or faulty
- A charging socket fuse is blown, or the socket or its connector is damaged
- The cable harness between the charging socket and the battery charger control module (OBC) is damaged, or OBC is damaged
Co możesz zrobić
- 1Read out and erase the fault code, charge again and see whether it comes back
- 2Check that the charging cable is not damaged and, if possible, try another charging cable that is approved for the car
- 3Have a workshop check that the fuse for the charging socket is intact. It sits in the fuse box at the socket
- 4Have a workshop check that the charging socket and its connector are not damaged and that the connectors sit firmly without play
- 5Have a workshop check the CAN wires and the harness to the socket. Replace the module only if needed. Do not work on the high voltage system yourself
Objawy, które możesz zauważyć2
- Charging the high voltage battery from an external charging cable does not happen, is reduced or does not work correctly
- The LED on the charging cable or the charging socket shows a fault and charging is reduced
Na co może wpływać usterka1
- Charging the high voltage battery is not possible
