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)
  • Rear motor IGBT temperature sensor (Upper/Lower limit malfunction)
 
 
DTC SET CONDITIONS
Logic Flow Chart
Check Condition
  • Within 1.5 seconds after the REMCU power supply voltage is 8.0 volts or more.
  • The soaking time is 600 seconds or more.
  • IGBT status: OFF (Shutdown)
Judgment Criterion
  • The difference between the IGBT temperatures A and B is 11°C (52°F) or more for 0.8 second or more.
  • The difference between the IGBT temperatures A and C is 11°C (52°F) or more for 0.8 second or more.

TROUBLESHOOTING HINTS
  • Malfunction of the rear motor (malfunction of the REMCU)
 
 
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.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 rear motor assembly (Refer to MOTOR (ELECTRIC MOTOR UNIT) REMOVAL AND INSTALLATION). Then,
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).
 
2.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.
