-

Harness connector E5

-

Harness connector E34

-

Harness connector B40

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 F14 and E5.

2. Check the continuity between the harness connector terminals.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair the main line between the A/T assembly and the harness connector F14.

3.

CHECK HARNESS CONTINUITY (OPEN CIRCUIT)

1. Disconnect the harness connectors E34 and B40.

2. Check the continuity between the harness connectors.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Repair the main line between the harness connectors E5 and E34.

4.

CHECK HARNESS CONTINUITY (OPEN CIRCUIT)

1. Disconnect the harness connectors B37 and B200.

2. Check the continuity between the harness connectors.

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)].

• Procedure for detecting root cause.
