<<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	DETERMINE IF MALFUNCTION IS ON CHARGING EQUIPMENT SIDE • Perform quick charging using charging equipment other than that used when the DTC was output. • Perform the DTC inspection for the PCM. (See DTC INSPECTION.) • Is DTC P0ABC:00 a present malfunction? Note • If DTC P0ABC:00 is displayed as a past malfunction, a malfunction in the charging equipment used when the DTC was output can be considered.	Yes	Go to the next step.
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 troubleshooting diagnostic procedure and perform the repair completion verification 2.
3	VERIFY WHETHER MALFUNCTION IS PRESENT OR PAST • Perform the DTC inspection for the PCM. (See DTC INSPECTION.) • Is DTC P0ABC:00 a present malfunction?	Yes	Go to the next step.
No	Go to the repair completion verification 2.
4	INSPECT HIGH VOLTAGE BATTERY FOR MALFUNCTION DEPENDING ON REPEATABILITY • Switch the main power to OFF • Switch the main power to ON (READY on) • Perform the DTC inspection for the PCM. (See DTC INSPECTION.) • Is DTC P0ABC:00 a present malfunction?	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 high voltage battery, then go to the repair completion verification 1. (See HIGH VOLTAGE BATTERY REMOVAL/INSTALLATION.)
No	Go to the repair completion verification 2.
Repair completion verification 1	VERIFY THAT VEHICLE IS REPAIRED Warning <<High voltage>> • Wear insulated gloves when working on a high voltage system. • Install/connect the part removed/disconnected during the troubleshooting procedure. • Clear the DTC recorded in the memory. (See CLEARING DTC.) • Replicate the vehicle conditions at the time the DTC was detected using the following procedure. Warning • While performing this step, always operate the vehicle in a safe and lawful manner. • When the M-MDS is used to observe monitor system status while driving, be sure to have another technician with you, or record the data in the M-MDS using the PID/DATA MONITOR AND RECORD capturing function and inspect later. ― Drive the vehicle under the snapshot data condition. • Perform the DTC inspection for the PCM. (See DTC INSPECTION.) • Is the same Pending DTC present?	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 PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION.)
No	Go to the next step.
Repair completion verification 2	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.
