I'm Igor Ramos. I spent over 10 years in new product introduction at Caterpillar, including serving as Technical Leader for the asphalt paver product line. My days were split between the engineering office and the shop floor — designing CAN-based systems, then watching field teams try to diagnose them.
The pattern was always the same: a machine goes down, a technician stares at a wiring diagram, swaps an ECU, and hopes for the best. Sometimes it worked. Usually it didn't. The problem wasn't the technician — it was that nobody had given them a repeatable method for isolating CAN faults.
I built CAN Bus Academy to fix that. The courses teach the same systematic diagnostic approach I used on the floor — stripped of academic filler, focused entirely on “what do I measure, where do I probe, and what do the readings tell me.”
