What you can do

- 2With the ignition on, check whether the code returns after switching the ignition off and on again
- 3Have a workshop check and correct the configuration, since the module must be reprogrammed with diagnostic equipment
- 4If the fault has only occurred occasionally, assess it with the workshop case by case
- 5After the work, clear the code and check that the battery does not discharge
