PCM Idle Learn Procedure: Notes

WARNING: This page is about a different car, the 2013 Acura MDX, 2012 Acura MDX, 2011 Acura MDX, and 2010 Acura MDX. 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.
Disassemble the engine or transmission.
NOTE: Clearing DTCs with the HDS does not require you to do the idle learn procedure.
