I have a broken Peugeot Ion.
After reading the failure codes via ODB2 connector, it seems a set of ECU (or parts) is not accessible. Is it related to any small power circuitry that is broken? Who can point me out to find the root cause?
Important notes:
Charging via AC connector to main battery and to 12V battery is possible.
Recently I have replaced the DC/DC charger by a used one. It does not help to solve the issue.
This car can not be driven on road since an unknown system/module is not working anymore.
