MONITOR EXECUTION CONDITIONS (Other monitor and Sensor)
Other Monitor (There is no temporary DTC set in memory for the item monitored below)
  • Battery charger control module (OBC) monitor
  • EV CAN monitor
Sensor (The sensor below is determined to be normal)
  • Not applicable
 
 
DTC SET CONDITIONS
Logic Flow Chart
Check Conditions
  • The EV system or the charging system is activated or the charge permission from PHEV-ECU is on.
Judgment Criterion
  • Change of the output voltage is more than 195 volts for 2 seconds.
 
 
OBD-II DRIVE CYCLE PATTERN
  • Refer to OBD-II Drive Cycle - Pattern 1 .
 
 
FAIL-SAFE AND BACKUP FUNCTION
  • The charge is stopped.
 
 
PROBABLE CAUSES
  • Open circuit or harness damage in high voltage circuits between on board charger/DC-DC converter and drive battery, or loose connector contact.
  • The high voltage fuse is melted down inside the REMCU.
  • The on board charger/DC-DC converter is failed
 
 
 
DIAGNOSIS
Required Special Tools
  • MB991223: Wiring harness set
  • MB992006: Extra fine probe
dangerWhen high voltage system components are served, be sure to pull service plugs to shut down high voltage (Refer to ).
dangerWhen pulling service plugs, wear the specified protective equipment (Refer to ).
STEP 1. Using scan tool (M.U.T.-IIISE), check whether the other system DTC is set.
Is the DTC related to PHEV-ECU system set?
Check PHEV-ECU system (Refer to P.54D-45).).
Go to Step 2.
 
STEP 2. Perform the continuity check of the high voltage fuse inside the REMCU.
Check of the high-voltage fuse inside inverter (Refer to GROUP 54Db - Check and Replacement of the High-voltage Fuse inside the Inverter ).
Is the check result normal?
Go to Step 3.
Replace the high voltage fuse (Refer to GROUP 54Db - Check and Replacement of the High-voltage Fuse inside the Inverter ). Then go to Step 5.
 
STEP 3. Check of open circuit and damage in P line and N line between on board charger/DC-DC converter connector and drive battery connector.
Is the check result normal?
Go to Step 4.
Repair the connector(s) or wiring harness. Then go to Step 5.
 
STEP 4. Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to OBD-II Drive Cycle - Pattern 1 .
(2) Check the DTC.
Is the DTC set?
Replace the on board charger/DC-DC converter (Refer to ). Then go to Step 5.
Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions ).
 
STEP 5. Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to OBD-II Drive Cycle - Pattern 1 .
(2) Check the DTC.
Is the DTC set?
Retry the troubleshooting.
The inspection is complete.
