Who we are

NOS Diagnostics & Calibrations is run by Nazir, owner / adas specialist, out of Garland, Texas. We work as the ADAS department for body shops, glass companies and independent repairers across the Dallas–Fort Worth metroplex — and we take select privately owned vehicles directly.

Every job follows the manufacturer procedure for that specific vehicle, and every job leaves with documentation you can put in the file.

What is ADAS?

Advanced Driver Assistance Systems use cameras, radar and sensors — mounted in the windshield, mirrors, grille and bumpers — together with the vehicle's computers to assist the driver. They power automatic emergency braking, forward and rear collision warning, adaptive cruise, blind spot detection, lane keeping and parking assist.

If those cameras and sensors are not aimed and calibrated to spec, the system reacts late, early or not at all. Calibration is what makes the safety system real.

What we do

ADAS Calibrations

Static and dynamic calibrations performed to OEM procedure for forward cameras, radar and blind spot modules — mobile at your shop or in our bay.

Details

Electrical Diagnostics

Fault-finding on the systems other shops hand back: SRS, network communication, sensors, power and ground faults — traced to the actual root cause.

Details

ECU Programming

Module programming and flashing with factory-level software, including setup and initialization of replacement modules.

Details

OEM Pre & Post Scans

Documented pre-repair and post-repair health scans with complete reports your estimator and insurer can attach to the file.

When is recalibration required?

Per manufacturer guidance, an ADAS-equipped vehicle needs recalibration after any of the following:

  • Windshield replacement
  • Collision repair
  • Front end alignment
  • Suspension repair or ride-height change
  • Camera or radar sensor replacement
  • SRS deployment
  • ECM, PCM or ECU replacement
  • Change in tire size
  • ADAS warning lights on or flashing codes

What our customers say

My girlfriend had a bunch of lights on her car, Nazir was really kind and explained everything. He fixed everything cheaper than what the dealership was originally expecting to charge her. He didn't try to get her on anything that she wouldn't know either. He was amazing and we were really glad we found his shop and didn't go to the dealership.

Dealership told me 5 hours to fix my sensors... came to this guy instead and he handled it quick! Great work, good price, and everything works perfect. Definitely recommend him!
LuisApril 28, 2026
I had my radar calibration completed here and couldn't be more satisfied with the service. The team was extremely professional, knowledgeable, and took the time to explain the entire process to me. They made sure everything was properly calibrated and tested before returning my vehicle. The turnaround time was quick, pricing was fair, and the quality of work gave me complete confidence that my safety systems are functioning exactly as they should.
CaseyFebruary 22, 2026
I give Nazir 5 stars, he knows what he doing and very knowledgeable and professional.
ObedApril 4, 2026
Excellent and professional. Would use again.
JoshMarch 15, 2026
Just reached out to ask about an issue that I have that appears to be firmware related. Dealer technicians couldn't fix it (or even acknowledge the issue existed). Good communication.

Highly trustworthy and great work.

Excellent service. Highly recommend.

Frequently asked questions

Does a windshield replacement require ADAS calibration?
On almost any vehicle with a forward-facing camera mounted to the glass, yes. Removing and replacing the windshield changes the camera's position and aim, and manufacturers require a recalibration afterward. Skipping it means lane keeping, automatic emergency braking and forward collision warning may react late, early, or not at all.
What is the difference between static and dynamic calibration?
Static calibration is done with the vehicle stationary in a controlled space, using OEM targets set at exact distances and heights. Dynamic calibration is done by driving the vehicle at a specified speed on suitable roads while the module learns. Many vehicles require both, in a specific order — the manufacturer's procedure decides, not the shop.
How long does a calibration take?
Most single-system calibrations run 1 to 2 hours once the vehicle is prepped. Vehicles needing multiple systems, or a static plus dynamic procedure, can take half a day. Pre-existing faults, ride-height problems or bad alignment can add time because they must be corrected before calibration is valid.
Do you come to my shop, or does the vehicle come to you?
Both. We run mobile service across the Dallas–Fort Worth metroplex for calibrations and diagnostics that can be completed on site. Static calibrations that require a level floor, controlled lighting and precise target placement are performed in our Garland bay.
What documentation do I get?
A complete pre-repair scan, a post-repair scan confirming systems are clear, and calibration documentation for each system we worked on — printable and ready to attach to the repair file for the customer or the insurer.
What happens if an ADAS system is not calibrated after a repair?
The system may still appear to work with no warning light while aiming several degrees off. At highway speed a small aiming error becomes a large targeting error, so braking and steering assistance can trigger at the wrong moment or fail to trigger at all. It is also a documented liability exposure for the shop that released the vehicle.
Do you work on privately owned vehicles, or only for shops?
Mostly shops — collision centers, glass installers, dealers and independent repairers — but we do take select privately owned vehicles directly. Send the vehicle details through the request form and we'll tell you where you stand.
What areas do you cover?
The Dallas–Fort Worth metroplex, from Garland outward: Dallas, Plano, Richardson, Mesquite, Rowlett, Sachse, Wylie, Allen, McKinney, Frisco, Carrollton, Irving, Grand Prairie, Arlington and Fort Worth. Outside that list, call and we'll tell you straight whether we can get there.
