DIAGNOSIS FUNCTION



WHEN DETECTING ON BOARD CHARGER ABNORMALITY


When the on board charger detects the abnormality, the diagnosis code should be output. The EV-ECU monitors to check whether the on board charger has abnormalities or not.

METHOD OF READING AND ERASING DIAGNOSIS CODES


Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - Diagnosis Function .
