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
1.M.U.T.-IIISE other DTC check
Check whether the DTC, which has the higher priority than this DTC, is set. (Refer to DTC Inspection Priority Chart).
Is the DTC set?
Troubleshoot the set DTC (Refer to DIAGNOSTIC TROUBLE CODE CHART). Then,
 
2.M.U.T.-IIISE other DTC check
Check whether the PHEV-ECU sets the following DTCs.
  • DTC No. P3123-15 Water Pump monitor circuit-High
  • DTC No. P3124-11 Water Pump monitor circuit-Low
  • DTC No. P3125-01 Water Pump Function Monitor A
  • DTC No. P3126-01 Water Pump Function Monitor B
  • DTC No. P3127-9F Water Pump Function Monitor C
  • DTC No. P3128-9E Water Pump Function Monitor D
Is the DTC set?
Troubleshoot the set DTCs (Refer to DIAGNOSTIC TROUBLE CODE CHART). Then, go to .
 
3.M.U.T.-IIISE other system DTC
Check whether the PHEV-ECU sets the DTC related to the radiator fan.
Is the DTC set?
Troubleshoot the set DTC (Refer to PHEV-ECU – DIAGNOSTIC TROUBLE CODE CHART DIAGNOSTIC TROUBLE CODE CHART). Then,
 
4.Check of the EV water cooling system
Check the EV water cooling system (Refer to EV COOLANT LEAK CHECK).
Is the check result normal?
Replace the power drive unit (Refer to POWER DRIVE UNIT REMOVAL AND INSTALLATION). Then,
Repair or replace the faulty part. Then, replace the power drive unit (Refer to POWER DRIVE UNIT REMOVAL AND INSTALLATION). Then,
 
5.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?
Retry the troubleshooting.
The procedure is complete.
