OBDLink MX+ (Diesel) vs AI Diesel Tech — FAQ
Is AI Diesel Tech an OBD adapter?
No. AI Diesel Tech is guided diagnostic reasoning software. It does not create a physical link to the vehicle — that is what an adapter like OBDLink MX+ does.
Does MX+ tell me what to test next on SCR faults?
No. OBDLink MX+ is hardware connectivity. It enables communication for compatible apps and software, but it does not provide diagnostic process guidance on its own.
Can I use both together?
Yes. Use OBDLink MX+ with compatible software to access codes and data, then use AI Diesel Tech to structure the diagnostic path and guide test execution.
Does AI Diesel Tech require OBDLink specifically?
No. AI Diesel Tech is a software platform that works alongside any scan tool or adapter setup. It is a diagnostic reasoning layer, not a hardware-dependent product.
Which product reduces misdiagnosis more?
AI Diesel Tech. It provides a structured test sequence that prevents common misdiagnosis patterns like replacing sensors before confirming root cause.
Which product creates the physical data link?
OBDLink MX+. It is the hardware adapter that bridges the vehicle diagnostic port to compatible apps and software.
What is the key buying mistake?
Assuming an adapter alone equals professional diagnostic process. An adapter provides connectivity; AI Diesel Tech provides the decision structure for what to do with the data.
Does AI Diesel Tech work on smartphones?
Yes. AI Diesel Tech is a PWA mobile app that works on any smartphone or tablet without installation. No dongle or hardware adapter is required.
Can I upload scan tool screenshots to AI Diesel Tech?
Yes. DieselVision™ allows you to snap a photo of your scan tool screen and get instant fault logic, OCR code extraction, and a guided test sequence — no manual lookup required.
Does AI Diesel Tech include a sensor location index?
Yes. The Heavy-Duty Sensor Location Index covers MAP, IAT, EGT, NOx, DPF pressure, fuel rail, EGR, crank/cam, boost, turbo speed, oil pressure, coolant temp, and DEF level sensors across Cummins, PACCAR, and Detroit platforms.
