To help with diagnosing faults Picoscope Automotive Diagnostic Software contains reference topics on vehicle components and systems—including sensors, actuators, ignition and CAN Bus.

Each topic shows you how to connect the automotive diagnostic equipment, gives advice on what the waveform should look like and gives general technical information on the component being tested.

Listed below are details of all the topics that are included in the software. Follow the links below for examples of some of the topics included—these example topics are also included in the FREE demo version of the automotive software.
