The majority of ECUs sent for test are found not to be faulty.
This begs the obvious question “what could the problem be on the vehicle” ATC will endeavour to offer advice on potential causes of your vehicle fault once the ECU has been eliminated.
We have access to a vast database of vehicle technical information such as Wiring / Pin diagrams, cross references, and technical bulletins.
We are more than happy to discuss issues within the context of products that we have tested or supplied and while we remain sympathetic to any vehicle issue that you may be trying to cure we do not have unlimited resources to provide a free helpline for all vehicle faults.
For technical support please call 01543 427900 or contact us here.
