DTC Confirmation Procedure
1)Set ignition “ON”.
2)Keep accelerator pedal at fully depressed position for 2 sec.
3)Release accelerator pedal for 2 sec.
4)Repeat Step 2) – 3) 3 times.
DTC Troubleshooting
| Step | Action | Yes | No |
|---|---|---|---|
| 1 |
Was “Engine and Emission Control System Check” performed?
|
Go to Step 2.

| 2 |
Throttle actuator drive circuit check
1)With ignition “OFF”, disconnect “C01” and “E01” connectors of ECM and electric throttle body assembly connector.
2)Check for proper terminal connection to “C01” and “E01” connectors and electric throttle body assembly connector.
3)If connections are OK, check the following points.
•Resistance of “A1” and “A2” circuits: less than 1 Ω
•Resistance between each of “A1” and “A2” circuits and ground: infinity •Resistance between “A1” circuit terminal and other terminal at electric throttle body assembly connector: infinity •Resistance between “A2” circuit terminal and other terminal at electric throttle body assembly connector: infinity •Voltage of “A1” and “A2” circuits: approx. 0 V (When ignition is “ON”) Is check result OK?
|
Go to Step 3.
|
Repair or replace defective wire harness.

Electric throttle body assembly check
1)Check electric throttle body assembly for performance.
Is check result OK?
|
Replace ECM and recheck DTC.
|
Replace electric throttle body assembly.
