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.

NOTE: The following procedure applies only to the TECH 1 Scan tool.
Consult the owners manual of the Scan tool being used for specific instructions on how to perform the "IDLE LEARN" procedure.

1. Restore battery power.

2. Shift transaxil to PARK (A/T), NEUTRAL (M/T).

3. Connect Tech 1 Scan tool.

4. Select "IAC SYSTEM," then "IDLE LEARN" in the "MISC TEST" mode.

5. Proceed with idle learn as directed.

This procedure will allow the ECM memory to be updated with the correct IAC valve position and provide a stable idle quality.
