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.Proportional valve (clutch) check

Check the proportional valve (clutch) [Refer to Transaxle - Proportional Valve (Clutch) Check PROPORTIONAL VALVE CHECK

Is the check result normal?

Replace the valve body assembly (Refer to Transaxle Overhaul - Front Transaxle DISASSEMBLY AND ASSEMBLY

). Then,

2.Check of short to ground circuit in SOL line between PHEV-ECU and proportional valve (clutch)

Is the check result normal?

Repair the connector(s) or wiring harness. 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 PHEV-ECU (Refer to PHEV-ECU 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

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?

Retry the troubleshooting.

The procedure is complete.
