MONITOR EXECUTION CONDITIONS (Other monitor and Sensor)
Other Monitor (There is no temporary DTC set in memory for the item monitored below)
  • Not applicable
Sensor (The sensor below is determined to be normal)
  • Power drive unit current sensor
  • Power drive unit voltage sensor
  • Generator position sensor
 
 
DTC SET CONDITIONS
Logic Flow Chart
Check Condition
  • Power drive unit (GCM) power supply voltage is 8.0 volts or more.
  • The motor speed is between 1,000 rpm and 13,000 rpm.
  • Time after above conditions satisfy is 0.2 second or more.
  • IGBT Status: ON
Judgment Criterion
  • The magnetic flux is less than the normal flux for 0.5 second or more.
 
 
OBD-II DRIVE CYCLE PATTERN
 
 
TROUBLESHOOTING HINTS
  • Malfunction of the generator
  • Malfunction of the EV oil cooling system
  • Malfunction of the radiator fan system
noteThe DTC may be set due to the 12V battery runout by leaving the vehicle with the power supply mode of the electric motor switch in ON condition.
 
 
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 the radiator fan.
Is the DTC set?
Troubleshoot the set DTC (Refer to PHEV-ECU – DIAGNOSTIC TROUBLE CODE CHART DIAGNOSTIC TROUBLE CODE CHART). 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?
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.Check of the EV oil cooling system
Check the EV oil cooling system (Refer to OIL LEAK CHECK).
Is the check result normal?
Replace the generator (Refer to GENERATOR REMOVAL AND INSTALLATION). Then,
Repair or replace the faulty part. Then, replace the generator (Refer to GENERATOR 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.
