COLUMBUS, Ind. — Zonar and engine manufacturer Cummins Inc. are now making Cummins’ Connected Diagnostics available to customers using Zonar's smart fleet management solution in an effort to help managers optimize their fleets.
By obtaining data through Zonar's V3 telematics control unit, Cummins Connected Diagnostics can wirelessly connect engines to Cummins for diagnosis of engine fault alerts, according to Cummins. Using algorithms unique to Cummins, Connected Diagnostics is designed to prioritize engine fault information and translate it into actionable recommendations that are then sent to operations managers in a report. The report was created to enable fleet managers to intervene when there is an urgent need for service, or to schedule a service event to prevent progressive damage to a vehicle.
"Offering even more of our customers access to Connected Diagnostics through Zonar's V3 device, we're able to deliver the information our customers need to avoid unexpected downtime and maintenance costs, as well as improve efficiencies across their operations," said Sherry Aaholm, vice president and chief information officer at Cummins.
"We believe that by offering the advantages of Connected Diagnostics through Zonar telematics, Cummins engine customers will be empowered with actionable data to proactively manage their engines and increase the uptime of their vehicles," said Larry Jordan, chief product officer at Zonar. "We see a large opportunity to help more fleets maintain a high level of fleet performance and safety while on the road through our Cummins relationship."
Connected Diagnostics is currently available on vehicles operating with Zonar's V3 solution. Zonar customers can enable Connected Diagnostics with an over-the-air update.
