Diagnosis Procedure

INFOID:0000000009653544

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

-

Power steering control module

-

ABS actuator and electric unit (control unit)

4.

Check the continuity between the power steering control module 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 power steering control module and the

ABS actuator and electric unit (control unit). 

NO

>> Repair the main line between the power steering control module and the ABS actuator and elec-

tric unit (control unit).

Diagnosis Procedure

INFOID:0000000009653545

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 E105

-

Harness connector M11

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.

-

ABS actuator and electric unit (control unit)

-

Harness connectors E105 and M11

2.

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

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair the main line between the ABS actuator and electric unit (control unit) and the harness

connector E105.

3.

CHECK HARNESS CONTINUITY (OPEN CIRCUIT)

Check the continuity between the harness connector and the data link 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 ABS actuator and electric unit (control

unit) and the data link connector. 

NO

>> Repair the main line between the harness connector M11 and the data link connector.
