Diagnosis Procedure

INFOID:0000000001162780

INSPECTION PROCEDURE

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 M69

-

Harness connector E7

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 M69 and E7.

2.

Check the continuity between the data link connector and the harness connector.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair the main line between the data link connector and the harness connector M69.

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 CAN system type decision again.
YES (Past error)>>Error was detected in the main line between the data link connector and the ABS actuator

and electric unit (control unit). 

NO

>> Repair the main line between the harness connector E7 and the ABS actuator and electric unit

(control unit).

and harness side).

-

Harness connector M14

-

Harness connector B3

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 M14 and B3.

2.

Check the continuity between the data link connector and the harness connector.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair the main line between the data link connector and the harness connector M14.

3.

CHECK HARNESS CONTINUITY (OPEN CIRCUIT)

Check the continuity between the harness connector terminals.

Is the inspection result normal?

YES (Present error)>>Check CAN system type decision again.
YES (Past error)>>Error was detected in the main line between the data link connector and the NAVI control

unit. 

NO

>> Repair the main line between the harness connector B3 and the NAVI control unit.
