  • 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 front motor resolver circuit
Check the front motor resolver circuit (Refer to RESOLVER 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?
The procedure is complete.
 
5.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 front motor (Refer to MOTOR (ELECTRIC MOTOR UNIT) REMOVAL AND INSTALLATION). Then,
Repair or replace the faulty part. Then, replace the front motor (Refer to MOTOR (ELECTRIC MOTOR UNIT) REMOVAL AND INSTALLATION). Then,
 
6.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.
