Modern vehicles are packed with multiple CAN networks, and diagnosing issues efficiently requires a solid approach. This class will show how to diagnose High-Speed (HS) CAN Bus problems with a focus on getting diagnostic answers using wiring diagrams, ohmmeters, voltmeters and scopes.
The main take away from this class is learning what you need to know to test a CAN bus, and then how to test it. The case studies will feature both Domestic and Asian vehicles, reinforcing the diagnostic approach and equipping technicians with practical skills for real-world applications.
Topics Covered:
• High-Speed CAN Bus Operation and a brief discussion on CAN Bus transceivers
• Using wiring diagrams to understand CAN Bus module relationships
• Finding & understanding Gateway modules
• HS Can Bus Testing strategies using an ohmmeter and voltmeter
• Using a scope to interpret HS CAN Bus failures
• Bonus PicoScope serial decoding
• Case Studies will include Domestic & Asian vehicles.
