Diagnosis Procedure

INFOID:0000000009949496

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 M77

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.

-

IPDM E/R

-

Harness connectors E105 and M77

2.

Check the continuity between the IPDM E/R harness connector and the harness connector.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair the main line between the IPDM E/R 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 IPDM E/R and the data link connector. 
NO

>> Repair the main line between the harness connector M77 and the data link connector.

Diagnosis Procedure

INFOID:0000000009949497

1.

CHECK CONNECTOR

1.

Turn the ignition switch OFF.

2.

Disconnect the battery cable from the negative terminal.

3.

Check the terminals and connectors of the ECM for damage, bend and loose connection (unit side and
connector side).

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair the terminal and connector.

2.

CHECK HARNESS FOR OPEN CIRCUIT

1.

Disconnect the connector of ECM.

2.

Check the resistance between the ECM harness connector terminals.

Is the measurement value within the specification?

YES

>> GO TO 3.

NO

>> Repair the ECM branch line.

3.

CHECK POWER SUPPLY AND GROUND CIRCUIT

Check the power supply and the ground circuit of the ECM. Refer to 

EC-129, "Diagnosis Procedure"

.

Is the inspection result normal?

YES (Present error)>>Replace the ECM. Refer to 

EC-16, "ADDITIONAL SERVICE WHEN REPLACING

CONTROL UNIT : Special Repair Requirement"

.

YES (Past error)>>Error was detected in the ECM branch line.
NO

>> Repair the power supply and the ground circuit.
