TROUBLESHOOTING HINTS
  • Malfunction of the rear motor assembly (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.
