YES

>> GO TO 4.

NO

>> Repair or replace error-detected parts.

4.

CHECK ECM POWER SUPPLY (MAIN)-1

1. Reconnect ECM harness connector.

2. Turn ignition switch ON.

3. Check the voltage between ECM harness connector terminals.

Is the inspection result normal?

YES

>> GO TO 5.

NO

>> GO TO 6.

5.

CHECK ECM POWER SUPPLY (MAIN)--2

1. Turn ignition switch OFF and wait at least 10 seconds.

2. Check the voltage between ECM harness connector terminals as per the following.

Is the inspection result normal?

YES

>> GO TO 9.

NO

>> GO TO 7.

6.

CHECK ECM POWER SUPPLY (MAIN) CIRCUIT

1. Turn ignition switch OFF.

2. Disconnect ECM harness connectors.

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.
Is the inspection result normal?

YES

>> Perform the trouble diagnosis for power supply circuit.

NO

>> Repair or replace error-detected parts.

7.

CHECK ECM RELAY CONTROL SIGNAL

Check the voltage between ECM harness connector terminals as per the following.

Is the inspection result normal?

YES

>> Check Intermittent Incident. Refer to 

GI-44, "Intermittent Incident"

.

NO

>> GO TO 8.

8.

CHECK ECM RELAY CONTROL SIGNAL CIRCUIT

1. Turn ignition switch 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.
