ECM/PCM Idle Learn Procedure: Notes

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.
• Clean or replace the throttle body.
