Important Information: Mazda makes no representations about the performance of third-party pass-thru devices. This pass-thru device list is provided voluntarily and as a courtesy. While our software meets SAE J2534, the pass-thru device manufacturer is responsible for making sure their pass-thru device operates properly on each Mazda vehicle and with Mazda software. We have listed the devices below because their manufacturers have attested that the tools have been validated to work. From time to time, we may test these devices. If we determine they do not operate properly or are obsolete, we may remove them from the list, without notice. Additionally, pass-thru devices listed here have been listed for their use with Mazda North American products only. While they may work with some European and other vehicles, they may not meet the requirements for those regions or operate properly.
