J-42598B GM Vehicle Data Recorder

  Professional mechanics know that about 80% of the vehicles that need diagnostics are pretty much straight forward diagnostic and repair situations. However the other 20% can really become frustrating especially when the problems are intermittent.

As a professional mechanic, you can not afford to spend excessive time trying to find these intermittent problems, thus you need a way to “catch” that problem when it occurs. This is a great tool for those intermittent problems that are hard to find.

Just attach the GM Vehicle Data Recorder to the OBD II interface on the vehicle and have the client drive the car until the problem occurs. While the client is driving his vehicle, GM Vehicle Data Recorder is constantly monitoring and recording data. When the problem sets a DTC, the GM Vehicle Data Recorder locks in the data.

  This tool can be used as a General Motors enhanced data real time diagnostic tool. Or remove it from the vehicle, attach it to pc via a RS232 to RJ45 cable (sold seperately).This simple procedure can save the professional mechanic lots of time and prevent the unnecessary replacement of good parts.
