What we diagnose
Diagnostics for Everything That Works
If it has an engine, a battery, or a control module — we can find out what's wrong with it.
Automotive Diagnostics
Cars, SUVs, and light trucks — accurate answers without the parts cannon.
Diesel Truck Diagnostics
Light, medium, and heavy-duty diesels — emissions, fuel, and aftertreatment systems.
Fleet Diagnostics
Keep work trucks and vans on the road with scheduled and on-call diagnostic support.
Construction Equipment
Excavators, loaders, skid steers, and more — diagnosed on your job site.
Agricultural Equipment
Tractors, combines, and implements — fast answers when the season can't wait.
Marine Diagnostics
Inboard and outboard engines, electrical systems, and fault-code analysis at the dock.
Electrical & Drivability
Wiring faults, sensor issues, rough running, and performance problems traced to the source.
Check Engine & Fault Codes
Beyond the code reader — we interpret data to find the actual failure.
No-Start & Intermittent Problems
The problems that come and go — and the ones other shops give up on.
Module Programming & Flashing
PCM, ECM, TCM, and other module programming, replacement-module setup, relearns, software updates, and vehicle-specific programming performed on-site when supported.
Remote Diagnostic Support
Advanced remote support for repair shops and technicians. TekQui can assist with difficult diagnostics, scan data, programming, troubleshooting, and technical guidance without requiring the senior diagnostician to be physically on-site.

Diagnostic Specialists, Not Parts Swappers
TekQui was built on years of hands-on diagnostic work — the kind of experience that comes from solving the difficult electrical, drivability, and no-start problems that general repair shops struggle with. The focus has always been the same: find the real cause, prove it with data, and fix it right the first time.
Today that expertise comes to you — fully mobile, with professional-grade equipment, serving individual vehicle owners and commercial operations alike. And as demand grows, TekQui is built to scale: more technicians, more specialties, and more service areas — with the same honest-diagnosis-first standard.
