MONITOR EXECUTION
Once per driving cycle
 
 
MONITOR EXECUTION CONDITIONS (Other monitor and Sensor)
Other Monitor (There is no temporary DTC set in memory for the item monitored below)
  • Non-volatile random access memory monitor
  • EV CAN monitor
  • BMU monitor
Sensor (The sensor below is determined to be normal)
  • Generator coil temperature sensor
 
 
DTC SET CONDITIONS
Logic Flow Chart
Check Condition
  • Power drive unit (GCU) power supply voltage is 8.0 volts or more.
  • Time after above conditions satisfy is 1.5 seconds or less.
  • The soaking time is 5,400 seconds or more.
  • The IGBT status of power drive unit is off (Shutdown).
Judgment Criterion
  • The absolute value of the difference between the value of U-phase coil temperature (front motor) and W-phase coil temperature (generator) remains 26°C (79°F) or more in 0.8 seconds.
  • The absolute value of the difference between the value of W-phase coil temperature (generator) and the oil temperature remains 22°C (72°F) or more in 0.8 seconds.

TROUBLESHOOTING HINTS
  • Malfunction of the power drive unit
  • Malfunction of the generator (malfunction of the W-phase coil temperature sensor)
  • Damaged wiring harness and connectors
 
 
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 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.Check of the generator coil temperature sensor circuit
Check the generator coil temperature sensor circuit (Refer to TEMPERATURE SENSOR CIRCUIT INSPECTION).
Is the check result normal?
Determine the faulty part and repair or replace it. Then,
 
3.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?
Replace the power drive unit (Refer to POWER DRIVE UNIT REMOVAL AND INSTALLATION), Then go to .
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).
 
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?
Replace the generator (Refer to GENERATOR REMOVAL AND INSTALLATION). Then,
The procedure is complete.
 
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.
