What does this fault code mean?
The battery charger control module (OBC) monitors that the lock motor in the charging socket works. The fault is set when OBC does not get an acknowledgement that the charging cable has been locked or unlocked. Charging the high voltage battery is not possible while the fault remains.
Possible causes
- The charging socket lock motor has failed
- Poor contact between the lock motor and the control module
What you can do
- 1Read out and erase the fault code, charge again and see whether it comes back
- 2Check that nothing, such as dirt or debris, prevents the charging cable from locking in the charging socket, and that the socket is not damaged
- 3Have a workshop check the lock motor, its cables and the cables to gateway OBC. Do not work on the high voltage system yourself
Symptoms you may notice3
- 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
- The lock function in the charging socket does not lock or unlock the charging cable
What the fault can affect1
- Charging the high voltage battery is not possible
