ECM : Diagnosis Procedure

INFOID:0000000010935623

1.

CHECK FUSE

1.

Turn ignition switch OFF.

2.

Check that the following fuse is not fusing.

Is the fuse fusing?

YES

>> Replace the fuse after repairing the applicable circuit.

NO

>> GO TO 2.

2.

CHECK GROUND CONNECTION

Check ground connection E5. Refer to Ground Inspection in 

GI-46, "Circuit Inspection"

.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair or replace ground connection.

3.

CHECK ECM POWER SUPPLY (ECM RELAY)

1.

Reinsert the fuse which pulled out.

2.

Turn ignition switch ON.

3.

Check the voltage between IPDM E/R terminal and ground.

Is the inspection result normal?

YES

>> GO TO 5.

NO

>> GO TO 4.

4.

CHECK ECM RELAY CONTROL SIGNAL CIRCUIT

1.

Turn ignition OFF.

2.

Disconnect ECM harness connector.

3.

Disconnect IPDM E/R harness connector.

4.

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

5.

Also check harness for short to ground and to power.

Is the inspection result normal?

YES

>> GO TO 6.

Fuse No.

. 

Is the inspection result normal?

YES

>> Replace IPDM E/R. Refer to 

PCS-60, "Removal and Installation"

.

NO

>> Repair or replace error-detected parts.

7.

CHECK ECM GROUND CIRCUIT FOR OPEN

1.

Turn ignition switch OFF.

2.

Disconnect ECM harness connector.

3.

Check the continuity between ECM harness connector and ground.

Is the inspection result normal?

YES

>> GO TO 8.

NO

>> Repair or replace error-detected parts.

8.

CHECK ECM POWER SUPPLY CIRCUIT
