There are many types of electronic modules in automo- biles today and new ones are springing up rapidly. In many cases, low frequency modules (i.e., ones without RF capabilities) can all be tested using a single system component architecture. This application note describes how best to use Agilent System Components to create a re-usable system tuned for low frequency automotive electronic functional test. Of the many electronic modules found in cars, here are a few of the most common: •Powertrain – engine control, transmission control •Body – lights, chimes, door locks, windows, windshield wipers •Anti-lock Brakes (ABS) •Airbag
