FIXD (Diesel) vs AI Diesel Tech — FAQ
Can FIXD replace AI Diesel Tech in a diesel shop?
No. FIXD is a consumer-oriented product designed for simplified code awareness on light-duty vehicles. AI Diesel Tech is built for professional diesel technicians working SPN/FMI, aftertreatment, and shop-floor root-cause diagnosis.
Is AI Diesel Tech a consumer code app?
No. AI Diesel Tech is a professional guided diagnostics platform for diesel technicians. It is designed around real diesel failure patterns, cascade codes, and shop process — not simplified consumer code explanations.
Which is better for SCR inducement triage?
AI Diesel Tech. It provides structured handling of DEF quality, SCR efficiency, DPF loading, NOx plausibility, and inducement consequences — the professional workflow FIXD does not replace.
Which is easier for a car owner reading a basic CEL?
FIXD. It is designed for consumer simplicity and light-duty code awareness. AI Diesel Tech is built for professional diesel technicians, not general consumers.
Does FIXD provide shop-floor process control?
No. FIXD is a consumer product. Professional diesel shop process control — including multi-code triage, aftertreatment sequencing, and repair documentation — requires a different tool category.
Does AI Diesel Tech replace OEM heavy-duty software?
No. AI Diesel Tech complements scan tools and OEM processes. It is a guided diagnostic reasoning layer, not a replacement for hardware scan capability or OEM service functions.
Who should buy AI Diesel Tech?
Technicians and shops that need structured diesel fault isolation — particularly for aftertreatment, derate, and multi-code events where process discipline reduces comebacks and parts waste.
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.
