Diagnostic Procedure

Warning

<<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 IF HIGH VOLTAGE-RELATED DTCs ARE OUTPUT •  Verify if high voltage-related DTCs are output for the following modules. ―  BECM ―  Drive motor control module ―  DC-DC converter ―  Battery charge control module (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)].) (See DTC TABLE [DRIVE MOTOR CONTROL MODULE (e-SKYACTIV)].) (See DTC TABLE [DC-DC CONVERTER (e-SKYACTIV)].) (See DTC TABLE [BATTERY CHARGE CONTROL MODULE (e-SKYACTIV)].)
		No	Go to the next step.
3	VERIFY WHETHER MALFUNCTION IS PRESENT OR PAST •  Switch the main power OFF and wait for 30 s or more. •  Switch the main power ON (READY on) and wait for 10 s or more. •  Perform the DTC inspection for the PCM. (See DTC INSPECTION.) •  Is DTC P0D6E:00 a present malfunction?	Yes	Go to the next step.
		No	Go to repair completion verification 2.
4	INSPECT HIGH VOLTAGE CABLE CONNECTOR OR TERMINALS FOR MALFUNCTION Warning <<High voltage>> •  Wear insulated gloves when working on a high voltage system. •  Remove the service plug. (See SERVICE PLUG REMOVAL/INSTALLATION.) •  After 10 min have elapsed after removing the service plug, perform a zero voltage verification at the voltage detection point of the junction box to verify that there is no electrical charge in the high voltage circuit. •  Inspect the applicable connector and terminal. (See CONNECTOR INSPECTION.) •  Are the connector and terminal normal?	Yes	Go to the next step.
		No	Replace the high voltage cable, then go to the repair completion verification 1. (See HIGH VOLTAGE CABLE REMOVAL/INSTALLATION.)
5	INSPECT ELECTRIC COMPRESSOR CONNECTOR OR TERMINALS FOR MALFUNCTION Warning <<High voltage>> •  Wear insulated gloves when working on a high voltage system. •  Verify that the service plug is removed. •  Inspect the applicable connector and terminal. (See CONNECTOR INSPECTION.) •  Are the connector and terminal normal?	Yes	Go to the next step.
		No	Replace the high electric compressor, then go to the repair completion verification 1. (See ELECTRIC COMPRESSOR REMOVAL/INSTALLATION.)
6	INSPECT JUNCTION BOX No.3 CONNECTOR OR TERMINALS FOR MALFUNCTION Warning <<High voltage>> •  Wear insulated gloves when working on a high voltage system. •  Verify that the service plug is removed. •  Inspect the applicable connector and terminal. (See CONNECTOR INSPECTION.) •  Are the connector and terminal normal?	Yes	Go to the next step.
		No	Replace the junction box No.3, then go to the repair completion verification 1. (See JUNCTION BOX No.3 REMOVAL/INSTALLATION.)
7	VERIFY IF MALFUNCTION IS CAUSED BY OPEN CIRCUIT IN HIGH VOLTAGE CABLE Warning <<High voltage>> •  Wear insulated gloves when working on a high voltage system. •  Verify that the service plug is removed. •  Inspect the following high voltage cable for continuity. ―  Junction box No.3 — electric compressor (See HIGH VOLTAGE CABLE INSPECTION [(E)].) •  Is the continuity of the high voltage cable normal?	Yes	Go to the next step.
		No	Replace the high voltage cable, then go to the repair completion verification 1. (See HIGH VOLTAGE CABLE REMOVAL/INSTALLATION.)
8	VERIFY IF MALFUNCTION IS CAUSED BY POOR INSULATION OF HIGH VOLTAGE CABLES Warning <<High voltage>> •  Wear insulating gloves when working on a high voltage system. •  Verify that the service plug is removed. Warning <<High voltage>> •  For the insulation resistance tester usage, refer to the insulation resistance tester instruction manual. Otherwise, electrocution could result from the voltage generated by the insulation resistance tester. Caution <<High voltage>> •  Use a insulation resistance tester using a testing range of 500 V or less because the high voltage applied by the insulation resistance tester may damage the parts. •  Inspect the insulation condition of the following high voltage cable. ―  high voltage battery — junction box No.3 (See HIGH VOLTAGE CABLE INSPECTION [(E)].) •  Is the insulation condition of the high voltage cable normal?	Yes	Go to the next step.
		No	Replace the high voltage cable, perform the repair completion verification 1. (See HIGH VOLTAGE CABLE REMOVAL/INSTALLATION.)
9	DETERMINE IF MALFUNCTION IS ELECTRIC COMPRESSOR •  Switch the main power OFF and wait for 30 s or more. •  Switch the main power ON (READY on) and wait for 60 s or more. •  Perform the DTC inspection for the PCM. (See DTC INSPECTION.) •  Is DTC P0D6D:00 a present malfunction?	Yes	Replace the electric compressor and perform the repair completion verification 1. (See ELECTRIC COMPRESSOR REMOVAL/INSTALLATION.)
		No	Go to 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.
		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.
