Diagnosis Procedure

INFOID:0000000009479130

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 F14

-

Harness connector E5

-

Harness connector E152

-

Harness connector M31

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair the terminal and connector.

2.

CHECK HARNESS CONTINUITY (OPEN CIRCUIT)

1. Disconnect the following harness connectors.

-

A/T assembly

-

Harness connectors F14 and E5

2. Check the continuity between the A/T assembly harness connector and the harness connector.

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 E152 and M31.

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 E152.

4.

CHECK HARNESS CONTINUITY (OPEN CIRCUIT)

1. Disconnect the connector of front air control.

2. Check the continuity between the harness connector and the front air control harness connector.
