Since the early 1990s, ANNECY ELECTRONIQUE has been developing and marketing tools for automotive maintenance workshops under its Exxotest® brand.

With the application of multiplexing to motor vehicles, the development of electrical troubleshooting tools rapidly gave way to the development of diagnostic solutions for on-board electronic components and architectures. In 2005, ANNECY ELECTRONIQUE equipped the after-sales network of a road vehicle manufacturer with an electronic diagnostic tool.
