PCM Idle Learn Procedure: Notes

WARNING: This page is about a different car, the 2011 Honda Pilot, 2010 Honda Pilot, and 2009 Honda Pilot. However, it is still accessible from the selected car via links, so may be relevant.

The idle learn procedure must be done so the PCM can learn the engine idle characteristics.

Do the idle learn procedure whenever you do any of these actions:

Replace the PCM.
Reset the PCM.
Update the PCM.
Replace or clean the throttle body.
When the engine or transmission is disassembled.

NOTE: Erasing DTCs with the HDS does not require you to do the idle learn procedure.
