MAIN LINE BETWEEN DLC AND 4WD CIRCUIT

Diagnosis Procedure

INFOID:0000000009175082

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 M40

-

Harness connector B69

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 M40 and B69.

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 M40.

3.

CHECK HARNESS CONTINUITY (OPEN CIRCUIT)

1. Disconnect the connector of 4WD control unit.

2. Check the continuity between the harness connector and the 4WD control unit harness connector.

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 4WD control

unit. 

NO

>> Repair the main line between the harness connector B69 and the 4WD control unit.

ECM BRANCH LINE CIRCUIT

Diagnosis Procedure

INFOID:0000000009175083

1.

CHECK CONNECTOR

1. Turn the ignition switch OFF.

2. Disconnect the battery cable from the negative terminal.

3. Check the terminals and connectors of the ECM for damage, bend and loose connection (unit side and

connector side).

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-173, "Diagnosis Procedure"

.

Is the inspection result normal?

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

EC-466, "Removal and Installation"

.

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

NO

>> Repair the power supply and the ground circuit.

Diagnosis Procedure

INFOID:0000000009175084

1.

CHECK CONNECTOR

1. Turn the ignition switch OFF.

2. Disconnect the battery cable from the negative terminal.

3. Check the terminals and connectors of the IPDM E/R for damage, bend and loose connection (unit side

and connector side).

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 IPDM E/R.

2. Check the resistance between the IPDM E/R harness connector terminals.

Is the measurement value within the specification?

YES

>> GO TO 3.

NO

>> Repair the IPDM E/R branch line.

3.

CHECK POWER SUPPLY AND GROUND CIRCUIT

Check the power supply and the ground circuit of the IPDM E/R. Refer to 

PCS-31, "Diagnosis Procedure"

.

Is the inspection result normal?

YES (Present error)>>Replace the IPDM E/R. Refer to 

PCS-32, "Removal and Installation"

.

YES (Past error)>>Error was detected in the IPDM E/R branch line.

NO

>> Repair the power supply and the ground circuit.
