EC-882 [QG (WITHOUT EURO-OBD)] IGNITION SIGNAL 15. CHECK IGNITION COIL GROUND CIRCUIT FOR OPEN AND SHORT 1. Turn ignition switch “OFF”. 2. Check harness continuity between ignition coil terminal 2 and engine ground. 3. Also check harness for short to power. OK or NG OK >> GO TO 16. NG >> Repair open circuit or short to power in harness or connectors. 16. CHECK IGNITION COIL OUTPUT SIGNAL CIRCUIT FOR OPEN AND SHORT 1. Disconnect ECM harness connector. 2. Check harness continuity between ECM terminals 60, 61, 79, 80 and ignition coil terminal 3. 3. Also check harness for short to ground and short to power. OK or NG OK >> GO TO 17. NG >> Repair open circuit or short to ground or short to power in harness or connectors. 17. CHECK IGNITION COIL WITH POWER TRANSISTOR Refer to EC-882, "Component Inspection" . OK or NG OK >> GO TO 18. NG >> Replace ignition coil with power transistor. 18. CHECK INTERMITTENT INCIDENT Refer to EC-644, "TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT" . >> INSPECTION END Component Inspection EBS00R2X ECM RELAY 1. Apply 12V direct current between ECM relay terminals 1 and 2. 2. Check continuity between relay terminals 3 and 5, 6 and 7. 3. If NG, replace ECM relay. Continuity should exist. Continuity should exist. Condition Continuity 12V direct current supply Yes OFF No PBIB0077E |
