sdConnect unable to communicate with ESP

I have the C4 multiplexer with a D630 laptop and have noticed I am unable to communicate or clear faults with ESP/BAS modules. It started with a 202 and I thought maybe it was just the car but now find it is not working with the 170 and 163 chassis.' It will scan the modules when performing a quicktest but I cannot access the module directly.

I am thinking it has something to do with DAS opening the HHT function. Any ideas? Thanks!

Have you checked all the pins from your diagnosis cable? If all pins are fine, measure conductivity from one end to the other.

It must be a fault within the C4
