Handheld tools are great and work for the most part but can sometimes fall short.
For example, recently I was trying to diagnose a ABS light on a friends 2004 F150 with my cheap scan tool and it couldn’t find anything.
I then took it to a local part store and they couldn’t find the problem either.
Not wanting to admit defeat I began reading online and found the Scan Tool 425801 for a PC. After looking at comparable options I thought I would try it out.
Short Video Review
It came with an OBD2 adapter that plugs into a USB port on a laptop, and software to diagnosis codes called OBDwiz.
It found the bad code on the F150 which was the rear speed sensor.
Keep in mind there are other scan tool options, such as using a smartphone or buying a good handheld tool.
If you dont want to lug around a laptop, smartphone Bluetooth OBD2 adapters can also be a cheap option.
One of the reasons a PC based solution can be better is the software and the ease of reading the interface.
There are many free and paid for OBD2 diagnostic software that is constantly being updated.
Also is it easy to simply try new software interfaces to see which one fits you. You can check out a list of PC based OBD2 software here. https://www.elmelectronics.com/help/obd/software/
After a code is found with a scan tool and it gives you an OBD2 code number, looking for information online is the next step.
Looking information up quickly online with a laptop is much easier at least for me. Reading through forums and watching YouTube videos is just easier on the eyes when doing research.
Of course, this is a personal option and using a smartphone scan tool is just as cheap as a laptop scan tool.
What works for me may not work for someone else so be sure to read other reviews for the best fit for you.
