ECM/PCM Idle Learn Procedure: Notes

WARNING: This page is about a different car, the 2012 Honda Fit, 2011 Honda Fit, 2010 Honda Fit, and 2009 Honda Fit. 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.
Replace or clean the throttle body.
Disassemble the engine or the transmission.

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