Navistar announced subscriptions to OnCommand Connection (OCC), the company's open architecture remote diagnostics system, have surpassed the 200,000 vehicle mark. "OnCommand Connection continues to grow its subscriber base by proving its value to a wide range of customers who are seeking a one-stop telematics solution for their entire fleets," said Terry Kline, Navistar senior vice president and chief information officer. "Through our strategy of integrating with a wide range of leading telematics service providers, we are able to provide unique, single-portal access to fleet managers and other customers who want their fleet's vehicle health information available through a single integrated portal. This open-architecture approach is helping many customers achieve significant uptime improvements, while also driving reduced maintenance costs."Vehicle status and diagnostic trouble code data from the TSPs are transmitted to OnCommand Connection, which then interprets this data and creates easy-to-understand vehicle health reports and recommended action plans for all brands of vehicles and engines, which can be accessed through online portal, emails and other types of alerts, as determined by the customer. By integrating and interpreting vehicle health information in a customer-friendly format, OnCommand Connection enables fleet users and other customers to achieve more efficient repairs and maintenance, better lifecycle value, and an overall lower total cost of ownership, giving them increased visibility into maintenance needs and better control of their business. OnCommand Connection is available now as a standard, no-charge feature on all new International trucks, as well as via aftermarket solutions supporting legacy International trucks and non-International vehicles.
