Fail-safe	• Refer to "DTC Table" and "Fail-safe Function Malfunction Contents Table". (See DTC TABLE [PCM (e-SKYACTIV)].)
Possible cause	• PCM malfunction • Drive motor control module malfunction • High voltage battery malfunction ― High voltage battery internal parts malfunction

System malfunction location

High voltage monitor: Correlation error (BECM and Drive motor control module)

Detection condition

• The PCM detects a difference between the voltage values measured by the BECM and the drive motor control module is the specified value or more.

Precondition

• The BECM and the drive motor control module are monitoring the voltage of the high voltage circuit.

Fail-safe

• Refer to "DTC Table" and "Fail-safe Function Malfunction Contents Table". (See DTC TABLE [PCM (e-SKYACTIV)].)

Possible cause

• PCM malfunction

• Drive motor control module malfunction

• High voltage battery malfunction

― High voltage battery internal parts malfunction

<<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	VERIFY BECM DTC • Perform the DTC inspection for the BECM. (See DTC INSPECTION.) • Are any other DTCs displayed?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting. (See DTC TABLE [BECM (e-SKYACTIV)].)
No	Go to the next step.
3	DETERMINE IF MALFUNCTION IS DRIVE MOTOR CONTROL MODULE. • Clear the DTC recorded in the memory. (See CLEARING DTC.) • Access the following PIDs using the M-MDS: (See PID/DATA MONITOR INSPECTION.) Drive motor contorol module: ― CAPACITOR_VOLT BECM ― HV_BATT_VOLT ― HV_CONTACTOR • Switch the main power to ON (READY on). • When the HV_CONTACTOR display is ON, is there a difference of 50 V or more between the following PID voltage values? ― CAPACITOR_VOLT ― HV_BATT_VOLT	Yes	Replace the inverter, then go to the repair completion verification 1. (See INVERTER REMOVAL/INSTALLATION.)
No	Go to the next step.
4	VERIFY PCM DTC • 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	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.

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.

VERIFY BECM DTC

• Perform the DTC inspection for the BECM.

(See DTC INSPECTION.)

• Are any other DTCs displayed?

Yes

Repair the malfunctioning location according to the applicable DTC troubleshooting.

(See DTC TABLE [BECM (e-SKYACTIV)].)

Go to the next step.

DETERMINE IF MALFUNCTION IS DRIVE MOTOR CONTROL MODULE.

• Clear the DTC recorded in the memory.

(See CLEARING DTC.)

• Access the following PIDs using the M-MDS:

(See PID/DATA MONITOR INSPECTION.)

Drive motor contorol module:

― CAPACITOR_VOLT

BECM

― HV_BATT_VOLT

― HV_CONTACTOR

• Switch the main power to ON (READY on).

• When the HV_CONTACTOR display is ON, is there a difference of 50 V or more between the following PID voltage values?

― CAPACITOR_VOLT

― HV_BATT_VOLT

Yes

Replace the inverter, then go to the repair completion verification 1.

(See INVERTER REMOVAL/INSTALLATION.)

Go to the next step.

VERIFY PCM DTC

• 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.
