UCDS Forum

I have an original UCDS V4 adapter with latest software 2.0.008.008 installed.
It works fine on my car, Mondeo MK5
but
I made a workbench for develop and testing purpose.
This contains the following units ; BCM, GWM, IPC, APIM, ACM and FCIM. All CAN-busses are wired in correct way, the units communicate
perfect with each other. But when i use the update wizard, and get info from vehicle i do not see always all the modules,
mostly only 2, BCM and APIM (they are on HS1) and sometimes i get all 6 of them.
Also the speed of module scanning sometimes differ.

If i do the same with ForScan and ELM327, it always works well.

I think it is a timing issue in software, can this be solved, had anybody the same experiance ?

Try add resister 120 Ohm on can bus UCDS (ucds not have terminated resistor)

This is not the problem. The UCDS adapter is connected to the GWM (Gateway Module) and the other site of the GWM is
connected to the CAN buses HS1,HS2,HS3 and MS. These CAN buses have on both sites 120 ohms resistors,
one site is internal the GWM itself, the other sites are inside IPC (HS2), FCIM(MS) and manual 120 ohm for HS1 and HS3
