DTC Troubleshooting
NOTE
Before this troubleshooting is performed, read the precautions for DTC troubleshooting referring to
"Precautions for DTC Troubleshooting".
Step
1 Was "Engine and Emission Control System Check"
performed?
2 Throttle 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?
3 Throttle 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?
4 Throttle actuator control relay check
1) Check throttle actuator control relay referring to "Main
Relay, Fuel Pump Relay, Starting Motor Control Relay,
