Idle Learn Procedure

1992 Chevrolet Lumina V6-204 3.4L DOHCSECTION Idle Learn Procedure




IDLE LEARN PROCEDURE: Any time the battery is disconnected, the programmed position of the 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:

1. After restoring battery power, connect the Tech 1 "Scan" tool or equivalent.
2. Select "IAC System," then select "Idle Learn" in the "Misc. Test" mode.
3. Proceed with idle learn as directed.
^ This procedure allows the ECM memory to be updated with the correct IAC valve pintle position, for the vehicle, and provide a stable idle speed.


WITHOUT "SCAN" TOOL:

1. Turn the ignition switch ON.
2. Ground the engine diagnostic lead for about five seconds.
3. Turn ignition switch off.
4. START the engine and check for proper idle operation.
