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 coil temperature sensor (Upper/Lower limit malfunction) <DTC No. P0A31-00>
  • Rear motor capacitor temperature sensor <DTC No. P30F2-1C>
  • REMCU temperature sensor (Upper/Lower limit malfunction) <DTC No. P30F2-1C>
 
 
DTC SET CONDITIONS
Logic Flow Chart <DTC No. P0A31-00>
Logic Flow Chart <DTC No. P30F2-1C>
Check Condition
  • Within 1.5 seconds after the REMCU power supply voltage is 8.0 volts or more.
  • The soaking time is 5,400 seconds or more.
  • IGBT Status: OFF (Shutdown)
Judgment Criterion <DTC No.P0A31-00>
  • The absolute value of the difference between the coil temperature (Phase U) and the coil temperature (Phase W) remains 13°C (55°F) or more in 0.8 seconds.
Judgment Criterion <DTC No.P30F2-1C>
  • The absolute value of the difference between the capacitor temperature and the control module temperature remains 18°C (64°F) or more in 0.8 seconds.
 
 
OBD-II DRIVE CYCLE PATTERN
 
 
TROUBLESHOOTING HINTS
  • Malfunction of the rear motor assembly (malfunction of the thermistor circuit system, malfunction of the REMCU, malfunction of the motor)
 
 
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.
