ECM/PCM Idle Learn Procedure (M/T)

ECM/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:

The ECM/PCM is replaced.
The ECM/PCM is reset.
NOTE: Erasing DTCs with the Honda PGM Tester or the HDS does not require you to do the idle learn procedure.
The throttle body is replaced.

Procedure:

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

2.	Do the ECM/PCM RESET in the CLEAR MENU with the Honda PGM Tester or the HDS.

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

4.	Start the engine, and hold it at 3,000 rpm (min^-1) with no load (in Park or neutral) until the radiator fan comes on, or until the engine coolant temperature reaches 90°C (194°F).

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.
