P0CFD-00: (OBC) DIAGNOSTIC PROCEDURE

Step	Inspection	Results	Action
1	PURPOSE: PERFORM DTC INSPECTION AND VERIFY IF MALFUNCTIONING PART IS BATTERY CHARGE CONTROL MODULE Switch the main power OFF. Disconnect the negative lead-acid battery terminal and wait for 1 min or more. (Refer to [NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION ] in service information). Connect the negative lead-acid battery terminal. (Refer to [NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION ] in service information). Clear the DTC recorded in the memory. (See CLEARING DTC .)

Perform the DTC inspection for the battery charge control module. (See DTC INSPECTION .) Is the same Pending DTC present? NOTE: If DTC P0CFD-00: is not displayed, a malfunction with the charging equipment used when the DTC was output can be considered.	Yes	Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error. (See MALFUNCTION DIAGNOSIS FLOW [CONTROLLER AREA NETWORK (CAN)] .) If the CAN communication is normal, replace the battery charge control module and perform the repair completion verification 1. (Refer to [ONBOARD CHARGER REMOVAL/INSTALLATION ] in service information).
1		No	The system is normal. (Explain to the customer that there is a possibility that a malfunction was detected due to a charging equipment malfunction). Go to the next step.
Repair completion verification 1	PURPOSE: VERIFY IF OTHER DTCs DISPLAYED Perform the DTC inspection. (See DTC INSPECTION .) Are any other DTCs displayed?	Yes	Repair or replace the malfunctioning location according to the applicable DTC troubleshooting.
