Logic Flow Chart A
Logic Flow Chart B
Check Condition A
  • Power drive unit (VCU) power supply voltage is 8.0 volts or more.
  • IGBT status: ON
Judgment Criterion A
  • The number of times that the reactor current-high switch is ON (When the maximum of the U/V/W phase current is more than +575 amperes or -575 amperes, Reactor current-high switch turns on) is three times or more.
Check Condition B
  • Power drive unit (VCU) power supply voltage is 8.0 volts or more.
Judgment Criterion B
  • The reactor current-high switch is ON (When the maximum of the U/V/W phase current is more than +575 amperes or -575 amperes, Reactor current-high switch turns on) for 0.4 seconds or more.

TROUBLESHOOTING HINTS
  • Malfunction of the power drive unit
  • Malfunction of the PHEV-ECU
  • Malfunction of the BMU system
 
 
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 system DTC
Check whether the PHEV-ECU sets the DTC related to contactor.
Is the DTC set?
Troubleshoot the set DTCs (Refer to DIAGNOSTIC TROUBLE CODE CHART). Then,
 
3.M.U.T.-IIISE other system DTC
Check whether the BMU sets the DTC related to voltage.
Is the DTC set?
Troubleshoot the set DTCs (Refer to DIAGNOSTIC TROUBLE CODE CHART). Then,
Replace the power drive unit (Refer to POWER DRIVE UNIT REMOVAL AND INSTALLATION). Then,
 
4.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.
