- Data Gathered From On-board Computers of Thousands of Commercial Vehicles Using Networkfleet -

SAN DIEGO, Nov. 28 /PRNewswire/ -- Networkcar(R) today announced the results of an analysis of diagnostic trouble codes (DTC) gathered from thousands of commercial vehicles across the U.S. that use its Networkfleet wireless vehicle management system. Networkfleet continuously monitors and collects data directly from a vehicle's engine computer and from a global positioning system (GPS). An analysis of aggregate Networkfleet data shows that 47 percent of diagnostic trouble codes for light/medium duty (OBD-II) vehicles were related to emissions issues and 24 percent were related to fuel consumption issues.
The Networkfleet system consists of an in-vehicle unit that wirelessly transmits diagnostic and GPS data. Fleet managers access a Web-based application to view specific vehicle data such as current location, fuel consumption, mileage, speed, and idle-time. Networkfleet automatically notifies fleet managers by e-mail immediately when a vehicle reports a diagnostic trouble code (DTC). Networkfleet provides the precise DTC code and a description identifying the specific nature of the problem. This allows technicians to procure parts ahead of time and begin working on the problem immediately instead of spending time trying to determine what is wrong.

Each month, Networkfleet intercepts 30,000 to 40,000 DTC codes from thousands of vehicles in fleets across the U.S. The top three individual diagnostic trouble codes collected by Networkfleet include:

* #1 Light Vehicle DTC (P0300) is related to cylinder misfires. Misfires can be indicative of poor maintenance or of a faulty or worn ignition system.

* #2 Light Vehicle DTC (P0171) indicates that the air to fuel mixture is suboptimal. This could be indicative of a faulty O2 sensor or a faulty/worn fuel pump.

* #3 Light Vehicle DTC (P0420) indicates that there may be a problem with the vehicle catalyst and that it should probably be replaced.

"For fleet managers, nothing is more important than keeping vehicles running and productive. Maintaining vehicles, including both repair and upkeep, can have a huge impact on a fleet's bottom line," said Paul Washicko, president of Networkcar. "Networkfleet enables them to have a proactive, preventive maintenance program and fix vehicle problems before they escalate into larger issues."
