Auto Test Tools is your Canadian Source for Diagnostic Tools and Accessories. Auto Test Tools is owned and operated by Auto Aide Technical Services (www.autoaide.ca). We can supply both Factory and Aftermarket equipment including scan tools. In addition to tools and equipment we fully support what we sell. Unlike many tool retailers who simply sell tools, we use the tools we sell on a daily basis to troubleshoot problem vehicles for other shops which enables us to not only know how the tools work but how to properly use them on the vehicle you work on every day. Support that few others can offer. Let us assist you in solving your diagnostic equipment needs.
