Toyota and Lexus Idle Re-learn Process

[Dean2]

 

 

If you are having issues with your idles speed, smoothness of idle etc, especially after disconnecting the battery or servicing the throttle body, you may wish to follow this idle relearn process.

Start the car,  take it for a short drive and make sure the temperature gauge is at full normal operating temp. Engage the parking brake, turn off ALL systems, radio, AC/climate control etc and shut the car off. Turn the key to on without your foot on the brake [don't start] then off. Turn to On again without starting, then off. Start the engine. Make sure the park/e-brake is still engaged and keep your foot on the brake. Put the car in drive, CAREFULLY take your foot off the brake and ensure the parking brake holds, and wait while the car adjusts to it's normal revs, should be 600-800 rpm in drive with AC/climate control off. This takes about 5 minutes. Switching the key on and off twice and starting engages the relearn mode.

If you are the visual learn type, there are YouTube videos of this process available.
