DIFF BRANCH LINE CIRCUIT

Diagnosis Procedure

INFOID:0000000009479141

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 differential lock control unit for damage, bend and loose con-

nection (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 differential lock control unit.

2. Check the resistance between the differential lock control unit harness connector terminals.

Is the measurement value within the specification?

YES

>> GO TO 3.

NO

>> Repair the differential lock control unit branch line.

3.

CHECK POWER SUPPLY AND GROUND CIRCUIT

Check the power supply and the ground circuit of the differential lock control unit. Refer to 

DLN-276, "Diagno-

sis Procedure"

.

Is the inspection result normal?

YES (Present error)>>Replace the differential lock control unit. Refer to 

DLN-311, "Removal and Installa-

tion"

.

YES (Past error)>>Error was detected in the differential lock control unit branch line.

NO

>> Repair the power supply and the ground circuit.

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 data link connector for damage, bend and loose connection

(connector side and harness side).

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair the terminal and connector.

2.

CHECK HARNESS FOR OPEN CIRCUIT

Check the resistance between the data link connector terminals.

Is the measurement value within the specification?

YES (Present error)>>Check the following items again.

• Decision of CAN system type.

• Not received CONSULT data (SELF-DIAG RESULTS, CAN DIAG SUPPORT MNTR).

• Procedure for detecting root cause.

YES (Past error)>>Error was detected in the data link connector branch line circuit.

NO

>> Repair the data link connector branch line.

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 combination meter 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 combination meter.

2. Check the resistance between the combination meter harness connector terminals.

Is the measurement value within the specification?

YES

>> GO TO 3.

NO

>> Repair the combination meter branch line.

3.

CHECK POWER SUPPLY AND GROUND CIRCUIT

Check the power supply and the ground circuit of the combination meter. Refer to 

MWI-31, "COMBINATION

METER : Diagnosis Procedure"

.

Is the inspection result normal?

YES (Present error)>>Replace the combination meter. Refer to 

MWI-90, "Removal and Installation"

.

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

NO

>> Repair the power supply and the ground circuit.
