P2100, P2103 THROTTLE CONTROL MOTOR RELAY EC-417 < COMPONENT DIAGNOSIS > [QR25DE FOR CALIFORNIA] C D E F G H I J K L M A EC N P O P2100, P2103 THROTTLE CONTROL MOTOR RELAY Description INFOID:0000000004349466 Power supply for the throttle control motor is provided to the ECM via throttle control motor relay. The throttle control motor relay is ON/OFF controlled by the ECM. When the ignition switch is turned ON, the ECM sends an ON signal to throttle control motor relay and battery voltage is provided to the ECM. When the ignition switch is turned OFF, the ECM sends an OFF signal to throttle control motor relay and battery voltage is not provided to the ECM. DTC Logic INFOID:0000000004349467 DTC DETECTION LOGIC DTC CONFIRMATION PROCEDURE 1. PRECONDITIONING If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at least 10 seconds before conducting the next test. TESTING CONDITION: Before performing the following procedure, confirm that battery voltage is more than 8V. P2100 >> GO TO 2. P2103 >> GO TO 3. 2. PERFORM DTC CONFIRMATION PROCEDURE FOR DTC P2100 1. Turn ignition switch ON and wait at least 2 seconds. 2. Start engine and let it idle for 5 seconds. 3. Check DTC. YES >> Go to NO >> INSPECTION END 3. PERFORM DTC CONFIRMATION PROCEDURE FOR DTC P2103 1. Turn ignition switch ON and wait at least 1 second. 2. Check DTC. YES >> Go to NO >> INSPECTION END Diagnosis Procedure INFOID:0000000004349468 1. CHECK THROTTLE CONTROL MOTOR RELAY POWER SUPPLY CIRCUIT 1. Turn ignition switch OFF. 2. Disconnect ECM harness connector. 3. Disconnect IPDM E/R harness connector F10. 4. Check the continuity between ECM harness connector and IPDM E/R harness connector.
