What the problem exactly is:

Tested car model is Rover 75 2004, customers try using the windows XP operating system to install software, have attempted many times to use the software to read EWS four times, all failed. All connections are no problem at all and the contact between Probes goes well.

Customers think the leading cause of this “Software EWS Read Failure” is that something goes wrong with DIN cable or the EWS unit breaks down. They even ask the customer service for the PCB diagram of DIN cable and Probe. So how to solve this problem?
