POWER SUPPLY AND GROUND CIRCUIT

4. CHECK GROUND CONNECTIONS
1. Turn ignition switch OFF.
2. Loosen and retighten ground screws on the body. Refer to EC-1055, "
Ground Inspection" .
OK or NG
OK >> GO TO 5.
NG >> Repair or replace ground connections.
5. CHECK ECM GROUND CIRCUIT FOR OPEN AND SHORT
1. Turn ignition switch OFF.
2. Disconnect ECM harness connector.
3. Check harness continuity between ECM terminals 1, 2, 3, 114 and body ground. Refer to Wiring Diagram.
4. Also check harness for short to power.
OK or NG
OK >> GO TO 6.
NG >> Repair open circuit or short to power in harness or connectors.
PBIB2020E
Continuity should exist.
