DIAGNOSTIC PROCEDURENLEC0641
1 INSPECTION START
Start engine.
Is engine running?
YesorNo
Ye s©GO TO 11.
No©GO TO 2.
2 CHECK ECM POWER SUPPLY CIRCUIT-I
1. Turn ignition switch ªONº.
2. Check voltage between ECM terminal 507 and ground with CONSULT-II or tester.
SEF895Y
OK or NG
OK©GO TO 4.
NG©GO TO 3.
3 DETECT MALFUNCTIONING PART
Check the following.
+Harness connectors M50, F24 (where fitted)
+Harness connectors M72, F44 (where fitted)
+Fuse block (J/B) connector M1
+10A fuse
+Harness for open or short between ECM and fuse
©Repair open circuit or short to ground or short to power in harness or connectors.
4 CHECK ECM GROUND CIRCUIT FOR OPEN AND SHORT
1. Turn ignition switch ªOFFº.
2. Disconnect ECM harness connector.
3. Check harness continuity between ECM terminals 104, 105, 106 and engine ground. Refer to Wiring Diagram.
Continuity should exist.
4. Also check harness for short to ground and short to power.
OK or NG
OK©GO TO 5.
NG©Repair open circuit or short to ground or short to power in harness or connectors.

2. Check continuity between ECM relay terminals 3 and 5, 7 and 6.
SEF296X
OK or NG
OK©GO TO 13.
NG©Replace ECM relay.
11 CHECK ECM POWER SUPPLY CIRCUIT-V
1. Turn ignition switch ªOFFº.
2. Disconnect ECM relay. (For ECM relay location, refer to ªEngine control component parts locationº, EC-1071.)
3. Disconnect ECM harness connector.
4. Check harness continuity between ECM terminals 107, 108, 109 and ECM relay terminal 7. Refer to Wiring Diagram.
Continuity should exist.
5. Also check harness for short to ground and short to power.
OK or NG
OK©GO TO 12.
NG©Repair open circuit or short to ground or short to power in harness or connectors.
