INSPECTION PROCEDURE

1.

CHECK CONNECTOR

1. Turn the ignition switch OFF.

2. Disconnect the battery cable from the negative terminal.

3. Check the following terminals and connectors for damage, bend and loose connection (connector side

and harness side).

-

Harness connector M89

-

Harness connector E64

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair the terminal and connector.

2.

CHECK HARNESS CONTINUITY (OPEN CIRCUIT)

1. Disconnect the harness connectors M89 and E64.

2. Check the continuity between the data link connector and the harness connector.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair the main line between the data link connector and the harness connector M89.

3.

CHECK HARNESS CONTINUITY (OPEN CIRCUIT)

1. Disconnect the connector of hybrid vehicle control ECU.

2. Check the continuity between the harness connector and the hybrid vehicle control ECU harness connec-

tor.

Is the inspection result normal?

YES (Present error)>>Check CAN system type decision again.

YES (Past error)>>Error was detected in the main line between the data link connector and the hybrid vehi-

cle control ECU. 

NO

>> Repair the main line between the harness connector E64 and the hybrid vehicle control ECU.

Diagnosis Procedure

INFOID:0000000004219040

1.

CHECK CONNECTOR

1. Turn the ignition switch OFF.

2. Disconnect the battery cable from the negative terminal.

3. Check the following terminals and connectors for damage, bend and loose connection (unit side and con-

nector side).

-

ECM

-

Harness connector E47

-

Harness connector E48

-

Junction block

-

Harness connector E30

-

Harness connector M1

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair the terminal and connector.

2.

CHECK HARNESS FOR OPEN CIRCUIT

1. Disconnect the connector of ECM.

2. Check the resistance between the ECM harness connector terminals.

Is the measurement value within the specification?

YES

>> GO TO 3.

NO

>> Repair the ECM branch line.

3.

CHECK POWER SUPPLY AND GROUND CIRCUIT

Check the power supply and the ground circuit of the ECM. Refer to 

EC-114, "Diagnosis Procedure"

.

Is the inspection result normal?

YES (Present error)>>Replace the ECM. Refer to 

EC-14, "ADDITIONAL SERVICE WHEN REPLACING

CONTROL UNIT : Special Repair Requirement"

.

YES (Past error)>>Error was detected in the ECM branch line.

NO

>> Repair the power supply and the ground circuit.
