What is J2534

Time:2015-10-13 Click:450

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.
