DTC P2102: Throttle Actuator Control Motor Circuit Low

Wiring Diagram
Refer to "DTC P2101: Throttle Actuator Control Motor Circuit Range / Performance: For Petrol Engine Model".
DTC Detecting Condition and Trouble Area
DTC detecting condition
Power supply voltage of throttle actuator control circuit is
less than 5 V for specified time even if throttle actuator
control relay is turned on.
(1 driving detection logic)
DTC Confirmation Procedure
1) With ignition switch turned OFF, connect scan tool.
2) Turn ON ignition switch and clear DTC using scan tool.
3) Start engine and run it for 1 min. or more.
4) Check DTC.
DTC Troubleshooting
NOTE
Before this trouble shooting is performed, read the precautions for DTC troubleshooting referring to
"Precautions for DTC Troubleshooting: For Petrol Engine Model".
Step
1 Was "Engine and Emission Control System Check"
performed?
2 Throttle actuator control relay circuit check
1) Remove ECM from its bracket with ECM connectors
connected.
2) Check for proper connection of ECM connector at "E23-
50" and "E23-17" terminals.
3) Turn ON ignition switch.
4) Measure voltage between "E23-17" terminal of ECM
connector and engine ground.
Is voltage 10 – 14 V?
3 Is "THR MOT" fuse in good condition?
4 Throttle actuator control relay circuit check
1) Remove throttle actuator control relay from relay box
with ignition switch turned OFF.
2) Check for proper connection to throttle actuator control
relay at "BLU/BLK", "BLU/RED", "BLU/ORN" and "GRN"
wire terminals.
3) Measure voltage between engine ground and each
"BLU/BLK", "BLU/RED" wire terminal with ignition switch
turned ON.
Is each voltage 10 – 14 V?
