DTC P0D67-844: On-Board Charger Malfunction [08/2014 - ]: Description

The electric vehicle charger assembly sends the status of the electric vehicle charger assembly to the plugin charge control ECU assembly as a CHST signal (charger operation state signal).

The status of the CHST signal (on-board charger operation status signal) has 3 patterns: stand-by, ready and abnormal interruption. The stand-by state indicates that the on-board charger is "on" and the electric vehicle charger assembly has started correctly. The ready state indicates that AC input power source voltage is received correctly and both the CHRQ signal (charging request signal) and CHEN signal (electric vehicle charger gate open/close request signal) have turned on. The abnormal interruption state indicates that an internal malfunction, overheating or fluctuation of AC input voltage is occurring in the electric vehicle charger assembly.

The electric vehicle charger assembly has self-protection functions. If a malfunction occurs, it sends the CHST signal (on-board charger operation status signal) to the plugin charge control ECU assembly to cancel charging. The electric vehicle charger assembly also limits its output if overheating occurs while charging or cancels charging when an internal malfunction occurs.
