A common question I get is “what is the best scan tool to add to my toolbox”? And to be honest, there is no one perfect answer to that. What I do share is that (in my opinion) many of the common driveability issues we face on a daily basis can be solved using even the most basic Global OBD II-capable tool. The key is in understanding what the tool is capable of doing, and that is the focus on this month’s “The Trainer” installment.
In our last session, I shared that the primary role of the ECM (Engine Control Module) is to keep an eye on vehicle emissions. Every test it performs, every code it generates, every problem it finds, is tied to an issue that will ultimately cause higher emissions to exit the tailpipe. Global OBD II provides us with a standardized set of DTCs (Diagnostic Trouble Codes) that all manufacturers have to incorporate and also requires the OEMs to provide access to the information we need to successfully diagnose those codes.
Most of the ten “modes” offered in OBD II you use every day. Mode $01 to read live data or Mode $03 to access current DTCs are just two examples. But I’m willing to bet there are many of you who have no clue what most of the other modes are, or what they have to offer in terms of diagnostic help.
While high end aftermarket scan tools and factory scan tools have their distinct benefits, the majority of the common DTCs you face every day can be solved once you unlock the full power of Global OBD II. Take a look at this month’s “The Trainer” to learn how.
