DIAGNOSIS
Required Special Tools:
  • MB992744: Vehicle communication interface-Lite (V.C.I.-Lite)
  • MB992745: V.C.I.-Lite main harness A
  • MB992747: V.C.I.-Lite USB cable short
  • MB992748: V.C.I.-Lite USB cable long
  • MB991223: Wiring harness set
  • MB992006: Extra fine probe
1.M.U.T.-IIISE other system DTC
Check whether the REMCU sets the following DTC.
  • DTC No.P30D1-16 Rear drive motor voltage-low
  • DTC No.P0C7A-00 Rear drive motor voltage-high
Is the DTC set?
Troubleshoot the set DTCs (Refer to DTC No. P0C7A-00 Rear drive motor voltage-high).
 
2.Check of the high-voltage fuse (30 A) for On Board Charger (OBC)/DC-DC converter
danger
  • Carry out the check on the high-voltage circuit while reading carefully the precautions on handling a high-voltage vehicle.
  • Wear the specified protection equipment during the check.
Check the continuity of the high-voltage fuse (30 A) for On Board Charger (OBC)/DC-DC converter in junction box (Refer to CHECK AND REPLACEMENT OF HIGH-VOLTAGE FUSE INSIDE THE JUNCTION BOX).
Is the check result normal?
Repace the high-voltage fuse (30 A) for On Board Charger (OBC)/DC-DC converter ( CHECK AND REPLACEMENT OF HIGH-VOLTAGE FUSE INSIDE THE JUNCTION BOX).
 
3.Visually check of the inside of the junction box
danger
  • Carry out the check on the high-voltage circuit while reading carefully the precautions on handling a high-voltage vehicle.
  • Wear the specified protection equipment during the check.
Visually check that there is no burnout, damage, foreign material inside the junction box.
Is the check result normal?
Replace the junction box (Refer to JUNCTION BOX REMOVAL AND INSTALLATION).
 
4.Check the installation of the P, N terminals on On Board Charger (OBC)/DC-DC converter.
danger
  • Carry out the check on the high-voltage circuit while reading carefully the precautions on handling a high-voltage vehicle.
  • Wear the specified protection equipment during the check.
Check that the P, N terminals of the On Board Charger (OBC)/DC-DC converter is installed to the junction box with specified torque.
Is the check result normal?
Repair the installation.
 
5.Check of continuity at the high-voltage circuit inside the junction box.
danger
  • Carry out the check on the high-voltage circuit while reading carefully the precautions on handling a high-voltage vehicle.
  • Wear the specified protection equipment during the check.
(1) Check the continuity of the high-voltage circuit inside the junction box (Refer to CONTINUITY CHECK FOR HIGH VOLTAGE CIRCUIT IN JUNCTION BOX).
Is the check result normal?
Check the tightening torque of the fuse, or repalce the junction box.
 
6.Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to OBD-II Drive Cycle OBD-II DRIVE CYCLE.
(2) Check the DTC.
Is the DTC set?
Repalce the On Board Charger (OBC)/DC-DC converter (Refer to ON BOARD CHARGER (OBC) &DC-DC CONVERTER REMOVAL AND INSTALLATION).
The trouble can be an intermittent malfunction (Refer to General Information - How to Use Troubleshooting/Inspection Service Points, How to Cope with Intermittent Malfunctions HOW TO COPE WITH INTERMITTENT MALFUNCTIONS).
