OTAir (Over-The-Air) Engine Updates for Cummins Vehicles


Cummins Connected Software Updates is an over-the-air programming solution for maximizing uptime and performance of Cummins-powered vehicles. This solution allows fleet managers and drivers who use Zonar telematics services to manage and deliver over-the-air programming to their Cummins engines using Zonar OTAir, an easy-to-use app on their smartphone.


Fleets that use Cummins Connected Software Updates receive the latest performance enhancements from Cummins by using OTAir, resulting in reduced downtime, increased cost savings, and improved vehicle health—without the need for any additional hardware.


Cummins Connected Software Updates empowers fleet managers and drivers with flexibility and an additional level of control over their vehicles. Similar to smartphones and computers, a fleet's engines also require regular updates. These updates are typically centered around specific performance improvements that help ensure a fleet's vehicles are always running at peak performance. With Connected Software Updates, fleet managers and drivers can perform engine software updates on a single vehicle or fleet of vehicles while on the road, allowing customers to scale and expedite service needs. While traditional calibration updates can take up to two days and cost hundreds of dollars in labor, updates through Cummins Connected Software Updates can take as little as five minutes from start to finish with no associated labor costs when using OTAir.


With Cummins Connected Software Updates, fleets using Zonar with Cummins engines can improve their operations through the following benefits:

  • Reduce downtime: With over-the-air updates, vehicles can spend more time on the road than at the shop receiving updates
  • Cost savings: A typical shop visit for an engine calibration update can cost in excess of $110 per visit, per vehicle
  • Increased vehicle health: With up-to-date software, vehicles run more efficiently and safely
  • Ease-of-use: Drivers can quickly approve updates on their smartphone or tablet and start the over-the-air process without hassle
  • Rapid updates: Fleet managers and drivers can work together to find optimal times, such as a driver's 30-minute rest break, to complete updates in as little as five minutes
  • Increase fleet control: Fleet managers are notified through the Cummins portal of available updates for specific engines, allowing them to schedule updates appropriately
  • Data security: OTAir includes VIN validation to help ensure the correct vehicle is receiving the correct update.
