WARNING: This page is about a different car, the 2009 Acura MDX, 2008 Acura MDX, and 2007 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.
- When the engine or transmission is disassembled.
NOTE:
Clearing the DTCs with the HDS does not require you to do the idle learn procedure.
