ECM/PCM Idle Learn Procedure: Procedure

  1. Make sure all electrical items (the A/C, the audio, the lights, etc.) are off.
  2. Reset the ECM/PCM with the HDS.
  3. Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode, and wait 2 seconds.
  4. Start the engine. Hold the engine speed at 3, 000 RPM without load (A/T in P or N, M/T in neutral) until the radiator fan comes on, or until the engine coolant temperature reaches 194°F (90°C).
  5. Let the engine idle for about 5 minutes with the throttle fully closed.
    NOTE: If the radiator fan comes on, do not include its running time in the 5 minutes.
