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
Disassemble the engine or the transmission

NOTE: Erasing DTCs with the HDS does not require you to do the idle learn procedure.


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

2. Reset the PCM with the HDS.

3. Turn the ignition switch to ON (II), and wait 2 seconds.

4. Start the engine. Hold the engine speed at 3,000 rpm without load (in P or N) 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.
