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 procedure:

• Replace the throttle body
• Clean the throttle body
• Replace ECM/PCM
• Update ECM/PCM
• Reset ECM/PCM
• When the engine or transmission is disassembled
  NOTE: Clearing DTCs with the HDS does not require you to do the idle learn procedure.
