2. Check the resistance between the display control unit harness connector terminals.

Is the measurement value within the specification?

YES

>> GO TO 3.

NO

>> Repair the display control unit branch line.

3.

CHECK POWER SUPPLY AND GROUND CIRCUIT

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

AV-224, "DISPLAY CON-

TROL UNIT : Diagnosis Procedure"

.

Is the inspection result normal?

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

AV-327, "Removal and Installation"

YES (Past error)>>Error was detected in the display 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 BCM 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 BCM.

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

Is the measurement value within the specification?

YES

>> GO TO 3.

NO

>> Repair the BCM branch line.

3.

CHECK POWER SUPPLY AND GROUND CIRCUIT

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

BCS-28, "Diagnosis Procedure"

.

Is the inspection result normal?

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

BCS-53, "Removal and Installation"

.

YES (Past error)>>Error was detected in the BCM 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-III data [SELF-DIAG RESULTS, CAN DIAG SUPPORT MNTR (“ECU

list” included)].

• Not copied from on-board diagnosis.

• 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.
