The webinar Diagnosis of CAN Bus with Information Available at the DLC, hosted by Al Santini from Consulab, breaks down the practical side of hunting down network gremlins in modern vehicles—because when modules stop talking, the whole rig can go dark, and shops need fast, reliable ways to get back on the road.

Relevant Training Systems

• CAN Bus Multiplex Network Diagnostic Training System (MP-750) — A fully functional Honda-based vehicle CAN Bus trainer with multiple OEM modules, DLC access, and real-world diagnostics for teaching operation, fault insertion, and repair of multiplex/CAN networks. https://daktic.com/product/multiplex-network-diagnostic-trainer
• CAN BUS Multiplex Training System (MP-1918-1D) — Double-sided trainer using J-1939 protocol with digital/analog I/O, DLC, and Deutsch connectors—ideal for hands-on CAN Bus network setup, communication testing, and troubleshooting in automotive or heavy-duty contexts. https://daktic.com/product/can-bus-multiplex-trainer
• Combination Automotive + CAN Bus Lighting Trainer (CL-MP-1918) — Double-sided setup covering modern lighting on one side and CAN Bus multiplex lighting control on the other, perfect for linking network diagnostics to real system responses like lights and modules. https://daktic.com/product/combination-automotive-can-bus-lighting-trainer

The session keeps it real on CAN Bus diagnosis: start at the DLC with resistance checks (60 ohms healthy, 120 if one’s missing, open if both are gone), grab scope captures to confirm clean mirror-image waveforms between CAN High and Low, and use bidirectional scan tools to ping modules, read VINs, and spot who’s awake or silent. Al Santini runs live examples on a Chevy Colorado and the MP-1918 trainer, showing how to rule out wiring, terminations, or bad modules without tearing the dash apart. These aren’t theoretical exercises anymore—every new vehicle rides on CAN (and faster networks like Ethernet coming fast), so intermittent dropouts, no-comm codes, or dead clusters turn into lost time and money if techs can’t pinpoint the fault quickly. Trainers with real DLC access and fault modes let students practice the full sequence—meter checks, scope work, scanner commands—building the confidence to handle networked vehicles that dominate today’s bays and will only get more connected tomorrow.
