What does this fault code mean?
Once the contactors close, voltage in the HV system should climb. The code is set when that climb in circuit B is too slow, which may be due to incorrect charging with an external cable, a fault in the on-board charger (OBC), or an open circuit in the high voltage cable.
Possible causes
- Incorrect charging from an external charging cable
- The fault may lie in the on-board charger (OBC)
- The high voltage cable in the circuit has an open circuit
What you can do
- 1Read and note the fault code, clear it and road test to check whether it returns
- 2Check that the charging cable is firmly connected at both the car and the outlet and that charging starts
- 3Have a workshop read the fault codes in the on-board charger (OBC) and remedy any faults found
- 4The high voltage system should only be handled by qualified personnel, so have a workshop carry out all work on the battery and other high voltage parts
Symptoms you may notice4
- Yellow warning symbol and message in the display
- Charging from the external cable does not happen
- The battery may be discharged or charge poorly
- The charging warning comes on or behaves abnormally
What the fault can affect1
