PCM Idle Learn Procedure: Notes
The PCM actively learns the idle characteristics whenever the engine is idling. The idle learn procedure must be done to ensure the PCM learns 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.
NOTE:
Clearing the DTCs with the HDS does not require you to do the idle learn procedure.
