Communication Issues, U Codes and Network Diagnostics
the advent of the computer controlled car the number of modules on said car
keeps growing. Networks are the central nervous system of the modern vehicle.
Network communications are essential to the proper operation and performance
of safety and infotainment systems. Networks also gave us the ability to
program modules and enhance our diagnostic abilities exponentially. However,
when there is a communication breakdown, or a module becomes non-responsive,
the diagnostics can be not so straight forward. Unplugging every module one
at a time can be a time consuming, and sometimes fruitless, task. To make
things worse, “U” Codes often leave “you” with little direction. This class
will introduce technicians to a simplified, straightforward and logical step
by step process to understanding and diagnosing network issues in the modern
vehicle. Tooling options and techniques will be discussed. Real world case
studies will be used to illustrate these techniques.
