Idle Speed/Throttle Actuator - Electronic: Adjustments

IDLE LEARN PROCEDURE
Any time the battery is disconnected, the programmed position of the Idle Air Control (IAC) valve pintle is lost, and replaced with a "default" value. To return the IAC valve pintle to the correct position, perform the following procedure:

- Restore battery power.
- Connect Tech I "Scan" tool.
- Select "IAC SYSTEM," then select "IDLE LEARN" in the "MISC TEST" mode.
- Proceed with idle learn as directed.

This procedure allows the Electronic Control Module (ECM) memory to be updated with the correct IAC valve pintle position, for the vehicle, and provide a stable idle speed
