PRESENTATION

The management and command system for operating a vehicle

today is fully automated to achieve better performance, lower fuel

consumption and greater comfort for the driver.

This is possible thanks to the technologies of the embedded

electronics, used in the execution of this work routine.

We will see how these work routines are defined and how to find

possible defects.

Let's get to know the various electronic components and how they

act on the electronic device.

Component testing and replacement, welding techniques and

rework on printed circuit boards.

The methods presented are based on the ISO9001 and QS9000

standards for automotive quality, training professionals able to

perform services with quality assurance.
