Video tutorial

The video shows how to perform the ISC reset on a 2008 Toyota Highlander Hybrid. The ISC valve is usually located in the intake manifold, specifically in the bypass duct, and regulates the incoming air. The reset is performed on the computer and ensures that the values related to this valve are perfect.

To do this, start the vehicle, press the brake, and then press the accelerator to rev the engine for about 30 seconds, until halfway through the battery charge. Then turn off the engine, wait a few seconds, and then restart the vehicle.

At this point, the reset is complete.
