INSPECTION PROCEDURE

1.

CONNECTOR INSPECTION

1.

Turn the ignition switch OFF.

2.

Disconnect the battery cable from the negative terminal.

3.

Disconnect all the unit connectors on CAN communication system.

4.

Check terminals and connectors for damage, bend and loose connection.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair the terminal and connector.

2.

CHECK HARNESS CONTINUITY (SHORT CIRCUIT)

Check the continuity between the data link connector terminals.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Check the harness and repair the root cause.

3.

CHECK HARNESS CONTINUITY (SHORT CIRCUIT)

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

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Check the harness and repair the root cause.

4.

CHECK ECM AND IPDM E/R TERMINATION CIRCUIT

1.

Remove the ECM and the IPDM E/R.

2.

Check the resistance between the ECM terminals.

Is the measurement value within the specification?

YES

>> GO TO 5.

NO

>> Replace the ECM and/or the IPDM E/R.

5.

CHECK SYMPTOM

Connect all the connectors. Check if the symptoms described in the “Symptom (Results from interview with
customer)” are reproduced. 

Inspection result

Reproduced>>GO TO 6.
Non-reproduced>>Start the diagnosis again. Follow the trouble diagnosis procedure when past error is

detected.

6.

CHECK UNIT REPRODUCTION

Perform the reproduction test as per the following procedure for each unit.
1.

Turn the ignition switch OFF.

2.

Disconnect the battery cable from the negative terminal.

3.

Disconnect one of the unit connectors of CAN communication system.
NOTE:
ECM and IPDM E/R have a termination circuit. Check other units first.

4.

Connect the battery cable to the negative terminal. Check if the symptoms described in the “Symptom
(Results from interview with customer)” are reproduced. 
NOTE:
Although unit-related error symptoms occur, do not confuse them with other symptoms. 

Inspection result

Reproduced>>Connect the connector. Check other units as per the above procedure.
Non-reproduced>>Replace the unit whose connector was disconnected.

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).
