PCM Idle Learn Procedure: Notes
WARNING: This page is about a different car, the 2006 Acura MDX, 2005 Acura MDX, 2004 Acura MDX, and 2003 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 PCM.
- Reset PCM.
- Update PCM.
- Replace or clean the throttle body.
NOTE:
Erasing DTCs with the HDS does not require you to do the idle learn procedure.
