Power decision-making with quality data.

Quality data drives quality insight—and smarter decisions around operations and fleet safety. Data such as speed, location, idling and diagnostic codes. Install the Zonar V4 telematics control unit in your light-, medium- and heavy-duty vehicles to collect the data needed to make informed decisions.

Analyze your entire fleet’s data using Zonar Ignition®. Or extend the data to your ERP, TMS, maintenance or other third-party systems using our API and custom integration services.

Track each vehicle with precision, in real time.

Use real-time GPS fleet tracking to enhance dispatching and routing, and lower vehicle mileage, idle and fuel costs—even amid ever-changing demands. The V4™ delivers precise location data, wherever that vehicle operates. With GNSS positioning, the V4™ uses GPS, GLONASS, Galileo and BeiDou satellites to calculate vehicle location.

Create geofences to be notified when vehicles arrive, leave or even speed at a jobsite, yard or street. Even create zones to ensure they’re not visiting restricted areas or establishments.

Frequently asked questions

What types of vehicles and environments are Zonar TCUs compatible with?

Zonar offers three TCU models tailored to different needs.

  • Zonar V4: Fits light-, medium- and heavy-duty vehicles.
  • Zonar V4R: A ruggedized version of the Zonar V4, designed for harsh environments. Features IP67 and IP69K ratings.
  • Zonar LD: A plug-and-play option for light-duty vehicles such as cars, vans and SUVs. Easily installed via the OBDII port.
How do Zonar TCUs help reduce vehicle downtime and maintenance costs?

Zonar TCUs capture Level 1 and Level 2 fault codes and other detailed engine data in real time, which enables fleet managers to identify and address issues early. Taking this proactive approach reduces downtime and helps avoid costly repairs, instead of a reactive approach of fixing what’s already happened.

How to Zonar TCUs stay connected and streaming what types of data?

Zonar TCUs capture dynamic geofencing, true idling, vehicle speed, odometer readings, and diagnostic code reporting. The devices use GPS, 4G LTE and multi-satellite connectivity to ensure precise and continuous data streaming, regardless of terrain, weather, or if they’re in an urban environment with tall buildings.

Can Zonar TCUs help with compliance and regulations, including the CARB Clean Truck Check program?

Yes, the Zonar V4 can automatically perform remote emissions scans to comply with the California Air Resources Board’s Clean Truck Check (CTC). The Zonar V4 also captures records and reports accurate driver hours to help fleets prevent Hours of Service (HoS) violations using Zonar Logs™.

Do top vehicle manufacturers trust Zonar TCUs?

Yes. The Zonar V4 passes all OEM testing for durability and reliability. The device integrates with platforms such as Daimler Trucks North America and International. And comes pre-installed or ready for retrofit in many Thomas Built Buses and IC Bus® vehicles.
