Firmware upgrade process is as follows: 1.Connect your interface via USB to your computer. 2.Go to settings of FCOM and perform test interface. 3.Click on “Apply Changes” button. 4.Click on “Upgrade firmware” button. Do not disconnect the interface during upgrading the firmware. The most important step in any diagnostic process is understanding the system design, the specific components used and its theory of operation. This article will provide an overview of the different systems and, in the case of the vacuum-based system, the evolution of design enhancements used to comply with the .020-in. gas vapor leak standard.Older wheel speed sensors are usually located outside the wheel hub. Like any other speed sensor, this can be an inductive sensor (magnet with a wire coil surrounding it) that produces an AC analog wave, or it can be digital, so that it produces a square wave signal. Some square wave wheel speed sensors can even detect whether the vehicle is
