Case Study: Cabarrus County Schools achieves reduced downtime and faster engine updates with Zonar Systems' OTAir

Cabarrus County Schools Reduces Downtime and Cut Costs With a Joint Zonar and Cummins Solution

Cabarrus County Schools, an eighth-largest North Carolina district based in Concord with 40 schools, 360 buses and roughly 26,000 students, needed a better way to keep its fleet running reliably without frequent garage visits. The district faced routine check-engine lights and time-consuming engine software updates that pulled buses out of service, cutting into student transport time and increasing maintenance costs.

By deploying Zonar OTAir and V4 telematics alongside Cummins Connected Diagnostics, Connected Advisor and Connected Software Updates, technicians can diagnose faults and push ECM updates via smartphone in as little as five to ten minutes instead of an hour. The solution centralized engine data, reduced downtime and unnecessary shop visits, improved engine performance and helped prevent costly breakdowns—saving time and lowering fleet operating costs.
