ECM/PCM Idle Learn Procedure: Notes

WARNING: This page is about a different car, the 2006 Honda CR-V and 2005 Honda CR-V. However, it is still accessible from the selected car via links, so may be relevant.

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

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

Replace ECM/PCM.
Reset ECM/PCM.
Update ECM/PCM.
NOTE: Erasing DTCs with the HDS does not require you to do the idle learn procedure.
Replace or clean the throttle body.
