TROUBLESHOOTING HINTS
  • Damaged wiring harness and connectors
  • Malfunction of the valve body assembly [proportional valve (clutch)]
  • Malfunction of the PHEV-ECU
 
 
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
  • MB991223: Wiring harness set
  • MB992006: Extra fine probe
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 continuity at proportional valve (clutch) connector (ground terminal)
(1) Disconnect the connector, and measure at the wiring harness side.
(2) Check the continuity between the proportional valve (clutch) connector (ground terminal) and body ground.
OK: Continuity exists (2 Ω or less)
Is the check result normal?
Repair the connector(s) or wiring harness in ground line between the proportional valve (clutch) and body ground. Then,
 
3.Check wiring harness and connectors for damage.
Check the wiring harness and connectors in SOL line between the PHEV-ECU connector and proportional valve (clutch) connector for damage.
Is the check result normal?
Repair the connector(s) or wiring harness. Then,
 
4.Check of open circuit in SOL line between PHEV-ECU and proportional valve (clutch)
Is the check result normal?
Repair the connector(s) or wiring harness. 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?
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).
 
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.
