TROUBLESHOOTING HINTS

Damaged wiring harness and connectors
Malfunction of the selector lever
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.Voltage measurement at selector lever connector (SFV2 terminal)

(1) Disconnect the connector, and measure at the wiring harness side.

(2) Change the power supply mode of the electric motor switch to ON (READY indicator: OFF).

(3) Measure the voltage between the selector lever connector (SFV2 terminal) and body ground.

OK: Approximately 5 V

Is the check result normal?

2.Check of short to ground circuit and open circuit in SFV2 line between PHEV-ECU and selector lever

Is the check result normal?

Repair the connector(s) or wiring harness. Then,

3.Voltage measurement at selector lever connector (SF04 terminal)

(1) Disconnect the connector, and measure at the wiring harness side.

(2) Change the power supply mode of the electric motor switch to ON (READY indicator: OFF).

(3) Measure the voltage between the selector lever connector (SF04 terminal) and body ground.

OK: Approximately 5 V

Is the check result normal?

4.Check of short to ground circuit in SF04 line between PHEV-ECU and selector lever

Is the check result normal?

Repair the connector(s) or wiring harness. Then,

5.Voltage measurement at selector lever connector (SF04 terminal)

(1) Measure the selector lever connector side by backprobing.

(2) Change the power supply mode of the electric motor switch to ON (READY indicator: OFF).

(3) Measure the voltage between the selector lever connector (SF04 terminal) and body ground.

Check condition	Normal condition
Selector lever: H, Nr, Nd	1.6 ± 0.5 V
other than above	2.98 ± 0.3 V

Is the check result normal?

Replace the selector lever (Refer to Transaxle - Selector Lever 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?

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

7.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.
