DTC P2103: Throttle Actuator Control Motor Circuit HighS6RW0D1104059
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.4Throttle actuator control relay circuit check
1) Remove throttle actuator control relay from individual
circuit fuse box No.1 with ignition switch turned OFF.
2) Check for proper connection to throttle actuator control
relay at “BLK/RED”, “GRY”, “BRN” and “GRN” wire
terminals.
3) Measure voltage between engine ground and each
“BLK/RED”, “GRY” wire terminal with ignition switch
turned ON.
Is each voltage 10 – 14 V?Go to Step 5. “BLK/RED” wire and/or
“GRY” wire is open or
high resistance.
5Throttle actuator control relay circuit check
1) Disconnect connectors from ECM with ignition switch
turned OFF.
2) Measure resistance at following connector terminals.
• Between “BRN” wire terminal of throttle actuator
control relay connector and “E01-45” terminal of ECM
connector
• Between “GRN” wire terminal of throttle actuator
control relay connector and “E01-32” terminal of ECM
connector
Is each resistance below 5
Ω?Go to Step 6. “BRN” wire and/or
“GRN” wire is open or
high resistance.
6Throttle actuator control relay check
1) Check throttle actuator control relay referring to “Main
Relay, Fuel Pump Relay, Starting Motor Control Relay,
Throttle Actuator Control Relay and Radiator Cooling
Fan Relay Inspection in Section 1C”.
Is it in good condition?Substitute a known-
good ECM and recheck.Replace throttle
actuator control relay. Step Action Yes No
DTC detecting condition Trouble area
Power supply voltage of throttle actuator control circuit is higher than
specified value for specified time even if throttle actuator control relay is
turned off.

DTC Troubleshooting
NOTE
Before this troubleshooting is performed, read the precautions for DTC troubleshooting referring to
“Precautions for DTC Troubleshooting”.

DTC P2111: Throttle Actuator Control System - Stuck OpenS6RW0D1104060
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. Step Action Yes No
1Was “Engine and Emission Control System Check”
performed?Go to Step 2. Go to “Engine and
Emission Control
System Check”.
2Throttle actuator control relay circuit check
1) Remove throttle actuator control relay from individual
circuit fuse box No.1 with ignition switch turned OFF.
2) Check for proper connection to throttle actuator control
relay at “BLK/RED”, “GRY”, “BRN” and “GRN” wire
terminals.
3) Turn ON ignition switch.
4) Measure voltage between engine ground and “E01-32”
terminal of ECM connector.
Is voltage 0 V?Go to Step 3. “GRN” wire is shorted to
other circuit.
3Throttle actuator control relay circuit check
1) Disconnect connectors from ECM with ignition switch
turned OFF.
2) Measure resistance between engine ground and “E01-
45” terminal of ECM connector.
Is resistance infinity?Go to Step 4. “BRN” wire is shorted to
ground circuit.
4Throttle actuator control relay check
1) Check throttle actuator control relay referring to “Main
Relay, Fuel Pump Relay, Starting Motor Control Relay,
Throttle Actuator Control Relay and Radiator Cooling
Fan Relay Inspection in Section 1C”.
Is it in good condition?Substitute a known-
good ECM and recheck.Replace throttle
actuator control relay.
DTC detecting condition Trouble area
Throttle position does not change by specified value during diagnosing throttle
valve at ignition switch turned OFF.
(1 driving detection logic)• Electric throttle body assembly
•ECM
