PCM Idle Learn Procedure: Notes

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.
Dissassemble the engine or the transmission.
NOTE: Erasing DTCs with the HDS does not require you to do the idle learn procedure.
