<<High voltage>>

• If necessary measures such as wearing the correct protective gear are not taken when inspecting or removing/installing the high voltage parts, it could cause electrical shock and result in serious injury or, in the worst case, death.

• Before inspecting or removing/installing the high voltage parts, refer to [HIGH VOLTAGE SERVICE CAUTIONS] in the general information and [High Voltage Part Inspection and Removal/Installation Notes] of the high voltage system service cautions and implement the necessary measures and preparations. (See HIGH VOLTAGE SERVICE CAUTIONS.) (See HIGH VOLTAGE SYSTEM SERVICE CAUTIONS.)

Step	Inspection	Results	Action
1	RECORD VEHICLE STATUS WHEN DTC WAS DETECTED TO UTILIZE WITH REPEATABILITY VERIFICATION • Record the snapshot data. Note • Recording can be facilitated using the screen capture function of the PC.	—	Go to the next step.
2	PERFORM DTC INSPECTION AND VERIFY IF MALFUNCTIONING PART IS BATTERY CHARGE CONTROL MODULE • Clear the DTC recorded in the memory. (See CLEARING DTC.) • Perform quick charging using charging equipment other than that used when the DTC was output. • Perform the DTC inspection for the Battery charge control module. (See DTC INSPECTION.) • Is DTC P0D53:00 displayed as a current malfunction? Note • If DTC P0D53:00 is displayed as a past malfunction, a malfunction in 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 CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [L.H.D. (E)]) (See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [R.H.D.].) If the CAN communication is normal, perform the diagnosis from Step 1. • If the malfunction recurs, replace the onboard charger, then go to the then go to the next step. (See ONBOARD CHARGER REMOVAL/INSTALLATION)
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	VERIFY IF OTHER DTCs DISPLAYED • Perform the DTC inspection. (See DTC INSPECTION.) • Are any other DTCs displayed?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting.
No	DTC troubleshooting completed.

Go to the next step.

PERFORM DTC INSPECTION AND VERIFY IF MALFUNCTIONING PART IS BATTERY CHARGE CONTROL MODULE

• Clear the DTC recorded in the memory.

(See CLEARING DTC.)

• Perform quick charging using charging equipment other than that used when the DTC was output.

• Perform the DTC inspection for the Battery charge control module.

(See DTC INSPECTION.)

• Is DTC P0D53:00 displayed as a current malfunction?

Note

• If DTC P0D53:00 is displayed as a past malfunction, a malfunction in 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 CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [L.H.D. (E)])

(See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [R.H.D.].)

If the CAN communication is normal, perform the diagnosis from Step 1.

• If the malfunction recurs, replace the onboard charger, then go to the then go to the next step.

(See ONBOARD CHARGER REMOVAL/INSTALLATION)

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

VERIFY IF OTHER DTCs DISPLAYED

• Perform the DTC inspection.

(See DTC INSPECTION.)

• Are any other DTCs displayed?

Yes

Repair the malfunctioning location according to the applicable DTC troubleshooting.
