Honda Idle Relearn Procedure: Simple 6 Steps Procedure

The Honda idle-stop process is something that you can easily do in the comfort of your home, and it will only take a little of your time.

And you will have accomplished your mission or resolved the issue you are trying to solve.

It is not a complex one to follow minimal effort is required, too, as long as you follow the instructions and steps keenly.

Below are outlined steps that will help you in a case where you want to conduct the procedure. The steps are as follows:

Step 1: Turn off all electrical

You will be required to make sure that you switch off all of the cars’ electrical items. These items include your car’s radio, lights, and air conditioner.

Step 2: Reset the Powertrain Control Module (PCM)

In this step, you will have to ensure your PCM/ECM with HDS reset.

This step is an easy one to do, and you can achieve it by disconnecting the battery of your car to ensure that you have removed the negative cable from the storm.

Alternatively, you can do this when you pull the FI‑ECU fuse that you will find under your hood fuse or the relaxed body to enable the reset process.

By doing this, you will make all the memory in the ECU wholly erased. And this probably is the fastest that your ECU can relearn.

Step 3: Switch on your ignition

After you have followed the above instruction, you can now go ahead and turn on the ignition switch (II), and then you will wait for two seconds.

Step 4: Start and hold the engine

At this point, you are supposed to start your engine, and then you are going to hold the engine speed at 3000 RPM (Revolutions per Minute) without load (in the park or neutral).

You have to continue doing this until when the radiator fan comes on.

Another way is that you can continue holding the engine until the engine’s coolant temperature reaches 90 degrees or 194 F.

Step 5: Leave your engine idle

Here, it would be best if you let your vehicle’s engine be idle for around 5 minutes, ensuring that the throttle has been fully closed.

You can do this by providing that your foot is off the pedal gas.

NOTE: just in case the radiator fan of your vehicle comes on, do not include its running time within the 5 minutes that you were letting your engine idle.

Step 6: Complete the process

After carefully following all of the above steps, at this point, you are going to shut off your car’s engine, and you will have completed the Honda idle relearn procedure successfully.

Remember that there should be no fans, radio, or lights, and this includes the dome light that turns on when you are opening a door of your vehicle.

Ensure that you stay inside your car and that everything is off until you have finished the whole process.

In a scenario when you feel like you want the windows of your car open, ensure you open them before you start the process of idle relearning your vehicle.

At least make sure that you have someone else with you while doing the procedure, as he will have to stand outside when you are inside the car.

He will inform you when the radiator fan comes on; making it impossible to see this if you are in your car and alone.

Honda Idle Relearn: What & How does It Work?

Honda idle is a process in which you can reprogram your car’s computer memory to be idle using a specified revolution per minute.

Normally it is a procedure that you can learn through your car user manual guide, or in cases where you cannot find it, it is effortless to access the information through Google search.

Just ensure that you are well aware of your car’s manufacture and the exact model of your vehicle.

When your vehicle’s computer has lost its connection with the throttle body, it might hinder some normal functioning of your car.

But you can resolve this using the Honda idle relearn method.

It works by allowing your vehicle’s computer to send a signal to the motor found in the ECB, which makes the throttle plate open slightly.

As a result, this will enable your car engine to keep on running without it stalling.
