GM Automotive Diagnostic Service Tools

General Motors is one of the foremost companies in the automotive industry, whose global headquarters is in Detroit, Michigan. GM was founded in 1908 and flourished as an automobile manufacturer from 1931 to 2007. Today, its excellence is apparent not only in many of the automotive brands under its corporate umbrella but also in its automotive diagnostics tools which help mechanics and average car owners fix problems more precisely.

Diagnostic Machines

With improvements in modern computing technology comes the modernisation of cars. Many newer cars are fitted with computers which enhance vehicle safety by making small but significant adjustments in certain situations in order to keep you in control. It presents a new challenge for mechanics and average owners because problems require more advanced tools. Enter the GM MDI scan tool paired with the Global Diagnostic System 2 (GDS2), which allows for ‘dealer level’ diagnostics capabilities by pulling codes, graphing data, as well as reprogramming controllers. The GM Tech 2 diagnostic tool is an oldie but goodie because it is quick, efficient and works well with compatible car systems.

Tool Sets

Now that you have your diagnostic tools to precisely identify problems, it is time to get GM car and truck tool sets and replacement parts to proceed with the repair. Advanced cars will benefit from having a complete set of steering wheel radio control buttons at the ready, while an ageing car might do well with a new set of window belt moulds to keep the side mirrors sliding smoothly up and down. If you’re getting a code that says ‘P0121 OBD-II Trouble Code: TPS ‘A’ Circuit Range Performance Problem’, you might need to replace the TPS with a new sensor or repairing the wirings as necessary.


For any sort of automotive repair job, having GM car and truck tools readily available is always a good idea. Prepare a surround moulding kit for the Commodore VE steering wheel if you want to freshen up your steering wheel. If you get a code for a faulty headlight, you may want to consider getting a replacement headlamp for your Holden car.
