This class includes CAN and LIN Bus Network diagnostics with a focus on getting answers using simple tools such as DVOM, test light, breakout box, scan tools & wiring diagrams.
The first goal of this class is to give you a good understanding of “Known Good” and once that is established, we will start to create faults to demonstrate what happens when particular problems arise. John will then move on to actual case studies of how he diagnoses different problems.
Topics covered:
Basic tool usage for complex network problems
How to simplify your network problem
Identifying the test locations & how tests are done
Tips for understanding network wiring diagrams
Finding difficult to locate modules
3 types of CAN busses
What is Fault Tolerance”
Understanding “Secured Gateways”
Case studies will include 2010 – 2018 vehicles and include problems such as no PCM communication, Blank Information Display Panels, inoperative steering wheel switch pods and several more.
The real benefit of this class is identifying the type of problem you are facing, and then applying simple testing to lead you to the fix. Although domestic examples are used the same testing procedures apply to Asian and European vehicles.
Vehicle networks are crowded with electronics; follow our path to keep things simple when diagnosing complex network issues.
