What does this fault code mean?
The battery charger control module (OBC) has a configuration ID that does not match the signal configuration that the central electronic module (CEM) sends on the CAN network. The control module still responds to diagnostic commands, but normal CAN communication does not work. Charging the high voltage battery is not possible while the fault remains.
Possible causes
- The module is not meant for this car, for example a used unit with different software or hardware
- Incorrect software version in the control module
- The software download was interrupted
What you can do
- 1Read out and erase the fault code, charge again and see whether it comes back
- 2Has the battery charger control module been replaced or reprogrammed recently? Tell the workshop, since it then needs to be configured for your particular car
- 3Have a workshop check that the control module has the right software for the car and reprogram it if needed
- 4The high voltage system may only be handled by authorised personnel. Do not work on it 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
- A text message and a warning symbol are shown in the display
What the fault can affect1
- Charging the high voltage battery is not possible
