DTC P2103: Throttle Actuator Control Motor Circuit HighS7RS0B1104069
Wiring Diagram
Refer to “DTC P2101: Throttle Actuator Control Motor Circuit Range / Performance”.
DTC Detecting Condition and Trouble Area
DTC Confirmation Procedure 1) With ignition switch turned OFF, connect scan tool.
2) Turn ON ignition switch and clear DTC using scan tool.
3) Ignition switch turned OFF for 20 sec. or more.
4) Turn ON ignition switch and check DTC. 5
Throttle actuator cont rol relay circuit check
1) Disconnect connectors from ECM with ignition switch turned OFF.
2) Measure resistance at the following connector terminals. • Between “BLU/ORN” wire termin al of throttle actuator
control relay connector and “E23-45” terminal of ECM
connector
• Between “RED/YEL” wire terminal of throttle actuator control relay connector and “E23-32” terminal of ECM
connector
Is each resistance below 5
Ω? Go to Step 6. “BLU/ORN” wire and/or
“RED/YEL” wire is open
or high resistance.
6 Throttle actuator control relay check
1) Check throttle actuator control relay referring to “Main Relay, Fuel Pump Relay an d Starting Motor Control
Relay Inspection in Section 1C”.
Is it in good condition? Substitute a known-
good ECM and recheck.
Replace throttle
actuator control relay.
Step
Action YesNo
DTC detecting condition Trouble area
Power supply voltage of throttle actuator control circuit is
more than 5 V for specified time even if throttle actuator
control relay is turned off.
(1 driving detection logic.) • Throttle actuator control relay circuit
• Throttle actuator control relay
•ECM
