Scotlands Leaders in 

Pass-Thru Technology

J2534, also known as Pass-Thru, ensures that we, as an independent repair shop 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, without this there is very little can be done on most modern cars.


We have been working with Pass-Thru technologies since the start and we are highly regarded as one of the industry leaders.
