J2534 Programming for Every Workshop

What is J2534 and Pass-Thru Programming?

J2534, also known as Pass-Thru, ensures that independent repair shops can work on modern cars and have cost-effective access to information and ECU programming downloads from vehicle manufacturer when required.


SAE J2534 is a communications standard adopted by vehicle manufacturers that enables compliant devices to reprogram vehicle ECUs. European and US legislation requires vehicle manufacturers to make vehicles, diagnostic and reprogramming applications that are compatible with J2534 devices.


Most modern cars can now be reprogrammed using the J2534 standard. Our products and services enable this without the need for separate, expensive OE tools for each brand.
