P2101 ELECTRIC THROTTLE CONTROL FUNCTION EC-917 < COMPONENT DIAGNOSIS > [QR25DE EXCEPT FOR CALIFORNIA] C D E F G H I J K L M A EC N P O 1. Check the voltage between ECM harness connector and ground. Is the inspection result normal? YES >> GO TO 7. NO >> GO TO 3. 3. CHECK THROTTLE CONTROL MOTOR RELAY POWER SUPPLY CIRCUIT 1. Disconnect ECM harness connector. 2. Disconnect IPDM E/R harness connector F10. 3. Check the continuity between ECM harness connector and IPDM E/R harness connector. 4. Also check harness for short to ground and short to power. YES >> GO TO 4. NO >> Repair open circuit or short to ground or short to power in harness or connectors. 4. CHECK THROTTLE CONTROL MOTOR RELAY INPUT SIGNAL CIRCUIT-II 1. Check the continuity between ECM harness connector and IPDM E/R harness connector. 2. Also check harness for short to ground and short to power. YES >> GO TO 5. NO >> Repair open circuit or short to ground or short to power in harness or connectors. 5. CHECK FUSE 1. Disconnect 15A fuse (No. 42) from IPDM E/R. 2. Check 15A fuse for blown. YES >> GO TO 6. NO >> Replace 15A fuse. 6. CHECK INTERMITTENT INCIDENT GI-42, "Intermittent Incident" . Is the inspection result normal? YES >> Replace IPDM E/R. NO >> Repair or replace harness or connectors. 7. CHECK THROTTLE CONTROL MOTOR OUTPUT SIGNAL CIRCUIT FOR OPEN OR SHORT 1. Turn ignition switch OFF. 2. Disconnect electric throttle control actuator harness connector. 3. Disconnect ECM harness connector. 4. Check the continuity between electric throttle control actuator harness connector and ECM harness con- nector.
