About NOS
NOS Diagnostics & Calibrations is an ADAS calibration and vehicle electronics shop in Garland, TX, serving collision centers, glass installers, dealers and vehicle owners across the Dallas–Fort Worth metroplex.
Nazir works the jobs other shops hand back: cameras that won't accept a calibration, radar modules that fail after a bumper repair, SRS lights that return a week later, modules that won't communicate after replacement. The work is diagnostic first — find the actual fault, then calibrate to the manufacturer's procedure and prove it with a scan.
That means shops get a vehicle back that's documented, not just cleared. It also means vehicle owners get an explanation of what was wrong in plain language, and a price before the work starts.
OEM procedure first
Every calibration follows the manufacturer's published procedure for that exact year, make and model — target distances, ride height, fuel level, tire pressure and road conditions included.
Documented before and after
Pre-repair and post-repair scans are recorded so the shop, the insurer and the vehicle owner all have proof the safety systems were verified.
Mobile when it saves you a tow
Most calibrations can be completed at your shop. When a job needs a controlled indoor space and level floor, it comes to the bay in Garland instead.
Straight answers on pricing
You get a quote before work starts, and a call before anything changes. No surprise line items.
