Diagnostic equipment

The obvious essential item for any fault finding is the diagnostic scan tool. Interrogation of diagnostic trouble codes, analysis of live data and use of actuator test functions are the usual starting point of component diagnosis.

However, many components are mis diagnosed because a trouble code was triggered by a mechanical condition that caused a perfectly good sensor to generate an implausible signal.

The electrical components testing techniques course explains how to use the diagnostic scan tool in conjunction with other tools, diagnostic equipment and technical information to carry out effective fault finding of components.
