Diagnosis Procedure

INFOID:0000000000964155

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).

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-133, "Diagnosis Procedure"

.

Is the inspection result normal?

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

EC-15, "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.
