Anyone know the idle learn procedure steps for Civic ?

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

2. Reset the ECM with the HDS.

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

4. Start the engine. Hold the engine speed at 3,000 rpm (min-1) without load (in 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.

6. Verify the IDLE LEARN in the DATA LIST is completed with the HDS

Thanks Potsy !
One more question, what the HDS is?

Can I do it without this ?
For instant the reset part, can I just disconnect the battery ?

The HDS is the Honda Diagnostic System, the laptop that connects to the car. I'm not sure whether you need it or not, but I'll send you a PM about where to find more info...

One more thing, on step 4 :
"Start the engine. Hold the engine speed at 3,000 rpm (min-1)"

What "min-1" means ? For 1 minute or something else ?

min-1 = revs per minute (rpm)

Oh ... I see.
Thanks again Potsy, much appreciated !
