  3. Check the following points.
    • Resistance of "A3" and "A4" circuits: less than 1 Ω
    • Resistance between each of "A3" and "A4" circuits and ground: infinity
    • Resistance between "A3" circuit terminal and other terminal at throttle actuator control relay connector: infinity
    • Resistance between "A4" circuit terminal and other terminal at throttle actuator control relay connector: infinity
    • Voltage of "A3" and "A4" circuits: 0 - 1 V (with ignition mode of keyless push start system in "ON")

Are they in good condition? 		 Replace ECM and recheck DTC, see ECM REMOVAL AND INSTALLATION . Repair or replace defective wire harness.
