Noregon Systems has added support for medium-duty General Motors vehicles in its PC-based diagnostics tool.

The inclusion is part of JPRO Commercial Fleet Diagnostics software v5.1, which adds information on Class 2-6 GM vehicles. The software also supports diagnostic coverage for on-highway heavy duty (Classes 7-8), and Ford applications with separately purchased coverage modules.

The software provides visibility of the entire vehicle condition on one easy-to-navigate screen, the company said. Bumper-to-bumper coverage on all 2002-2011 half-ton through 8500 series GMC and Chevy vehicles, including transmission, ABS, chassis and body controllers along with both gasoline and diesel engines with the ability to perform cylinder cut out tests on GM or Isuzu engines, is included.
