PCM Idle Learn Procedure

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 the PCM.

Reset the PCM.

Update the PCM.

Replace or clean the throttle body.

When the engine or transmission is disassembled.

NOTE:

Clearing the DTCs with the HDS does not require you to do the idle learn procedure.

The PCM memorizes the learning status in its memory after passed an hour from turning the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode. If you need to disconnect the battery terminals before memorizing the learning status in the PCM, jump the SCS line with the HDS, and wait 60 seconds, then disconnect the battery terminals.

Procedure

Make sure all electrical items (the A/C, the audio, the lights, etc.) are off.

Reset the PCM with the HDS.

Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode, and wait 2 seconds.

Start the engine. Hold the engine speed at 3,000 rpm without load (M/T in neutral, A/T and CVT in P or N) until the radiator fan comes on, or until the engine coolant temperature reaches 194 °F (90 °C).

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.

Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode.

Jump the SCS line with the HDS.

Wait 60 seconds, and exit the SCS mode with the HDS.
