Brummy

I have issues with the ABS system on my car, than  I could really do with Pscan showing me what is wrong. The car system is a Bosch 5.3 and when the interface failed on the original, I purchased a known good ECU and replaced with that. That behaves in the same way. I have confirmed the link wire from the OBD connector to the ECU harness plug is good as is the component earths, so I am at a loss to understand why there is no communication. Any help or guidance would be appreciated
