| Step | Check | Yes | No |
|---|---|---|---|
1 CHECK INPUT VOLTAGE OF ECM.
|
Is the voltage 10 - 13 V? | Go to step 2. | Repair the open or ground short circuit of power supply circuit. |
2 CHECK INPUT VOLTAGE OF ECM.
|
Is the voltage 13 - 15 V? | Go to step 3. | Repair the open or ground short circuit of power supply circuit. |
3 CHECK HARNESS BETWEEN ECM AND ELECTRONIC THROTTLE CONTROL.
|
