What is J2534?


SAE J2534 is a standard for communications between a computer and a vehicle. Government regulations require all automakers provide a J2534 service to everyone in the U.S. for re-flashing emissions related controllers. If you own a SAE J2534 Pass-Thru device, you can re-flash and, in some cases, diagnose vehicles with factory functionality.

In recent years the EPA, CARB, and European Union have required automotive companies to allow for emissions-related modules (ECM/TCM) to be reprogrammable without use of special and often very expensive factory tools, in an effort to reduce harmful emissions. Because of the success and ease of J2534 some manufacturers have now begun to offer factory diagnostics as well as reprogramming capabilities. To learn the history of J2534, click HERE.


Why do you need J2534?


Since the introduction of OBDII and leading up to modern Hybrids and EV's, computers and software in cars have been expanding at an exponential rate. In-car software is becoming one of the leading needs for service, and updating software may be the only way to fix some of these issues: drivability, fuel efficiency, power loss, fault codes, and durability of mechanical parts.

Studies indicate that 7 out of 10 vehicles on the road require a calibration update. Technicians exploring J2534 will find that it's a technology that is not only growing, but becoming essential. A J2534 tool will allow you to fix cars, grow profits by offering services previously sent to the dealership, and offer the services needed to retain customers.
