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 .

FAIL-SAFE AND BACKUP FUNCTION


The control is carried out, which keeps the safety driving by the preset control logic when the diagnostic trouble code is set. The diagnostic trouble code having the fail-safe function is as follows.
