What does this fault code mean?
The code concerns low temperature in the battery charger (OBC), which is measured by two temperature sensors built into it. At too low a temperature, charging from an external cable becomes weaker or stops altogether.
Possible causes
- Low ambient temperature
- Incorrect temperature sensor in the battery charger (OBC)
What you can do
- 1Check that the charging cable is fully connected and that its switch is on
- 2Once the temperature has become normal, charging should restart by itself; check that it does
- 3Have a workshop check the temperature in the battery charger and replace the control module if the fault remains
- 4Do not work on the high-voltage system yourself, for example the battery charger or its wiring; that is a job for a workshop
Symptoms you may notice2
- Charging of the high voltage battery from an external cable does not work or works poorly
- The lamp in the charging socket shows a fault or reduced charging
What the fault can affect2
- Charging of the high voltage battery may become weaker or stop completely
- The battery charger carries on charging by itself once the temperature is back to normal
