Reducevehicle downtime by days
Simplify engine updates for drivers

Turn downtime into drivetime.

Keeping your Cummins engines updated is now easier, faster and more cost effective.

On average, commercial vehicles travel more than 100,000 miles a year, and operate at all hours. They’re not always in the yard when an update’s available. Keeping their engines updated means coordinating expensive service appointments, and sending them to the shop so specialized technicians can perform the manufacturer-level updates. On top of those costs, vehicles in the shop are out of service for hours, maybe even days.

Now drivers and maintenance technicians can perform Cummins Connected Software Updates themselves, over the air, using the Zonar OTAir app on their smartphone.

Maintenance personnel can update multiple vehicles at a time in the yard. Drivers can update their vehicle any time they’re safely stopped, such as during rest breaks or pre-trip inspections.

Reduce expensive shop visits.

The cost for a typical shop visit for an engine calibration can start at more than $100. Factor in the resources needed to coordinate the visit and the vehicle’s downtime, and the cost of an engine update climbs—quickly. Now eliminate the need for pricey shop visits—saving valuable time and money—by updating engines using Cummins Connected Software Updates through Zonar OTAir.
