Description
Power supply for the throttle control motor is provided to the ECM via the throttle control motor relay. The throttle control motor relay is controlled ON/OFF 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.

Witch DTC is detected?
P2100 >> GO TO 2.
P2103 >> GO TO 3. 2.PERFORM DTC CONFIRMATION PROCEDURE FOR DTC P2100
Turn ignition switch ON and wait at least 2 seconds.
Start engine and let it idle for 5 seconds.
Check DTC. Is DTC detected?
YES >> Go to Diagnosis Procedure.
NO >> Inspection END 3.PERFORM DTC CONFIRMATION PROCEDURE FOR DTC P2103
Turn ignition switch ON and wait at least 1 second.
Check DTC. Is DTC detected?
YES >> Go to Diagnosis Procedure.
NO >> Inspection END
Diagnosis Procedure 1.CHECK THROTTLE CONTROL MOTOR RELAY POWER SUPPLY CIRCUIT
Turn ignition switch OFF.
Disconnect ECM harness connector.
Disconnect IPDM E/R harness connector.
Check the continuity between IPDM E/R harness connector and ECM harness connector.
Also check harness for short to ground and short to power. Is the Inspection result normal?
YES >> GO TO 2.
NO >> Repair open circuit, short to ground or short to power in harness or connectors. 2.CHECK THROTTLE CONTROL MOTOR RELAY INPUT SIGNAL CIRCUIT-II
Check the continuity between IPDM E/R harness connector and ECM harness connector.
Also check harness for short to ground and short to power. Is the Inspection result normal?
YES >> GO TO 3.
NO >> Repair open circuit, short to ground or short to power in harness or connectors. 3.CHECK FUSE
Disconnect 15 A fuse (No. 43) from IPDM E/R.
Check if 15 A fuse is blown. Is the Inspection result normal?
