Diagnosis Procedure

INFOID:0000000006179142

1.

CHECK HARNESS CONTINUITY (OPEN CIRCUIT)

1. Turn the ignition switch OFF.

2. Disconnect the battery cable from the negative terminal.

3. Disconnect the following harness connectors.

-

ECM

-

Combination meter

4. Check the continuity between the data link connector and the combination meter harness connector.

Is the inspection result normal?

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 main line between the data link connector and the combination

meter.

NO

>> Repair the main line between the data link connector and the combination meter.

2. Check the continuity between the combination meter harness connector and the harness connector.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair the main line between the combination meter and the harness connector M31.

3.

CHECK HARNESS CONTINUITY (OPEN CIRCUIT)

1. Disconnect the connector of ABS actuator and electric unit (control unit).

2. Check the continuity between the harness connector and the ABS actuator and electric unit (control unit)

harness connector.

Is the inspection result normal?

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 main line between the combination meter and the ABS actuator

and electric unit (control unit).

NO

>> Repair the main line between the harness connector E152 and the ABS actuator and electric unit

(control unit).
