I absolutely love Rheingold now that I got it working on my laptop, it has helped me with figuring out the problems I was having with my Park Assist retrofit. I wish mine were a simple sensor replacement, instead every so often I get both PDC and Park Assist malfunctions, and the code I'm getting is an "Ultrasonic Sensor: Short Circuit to B+ positive" error, but it isn't kind enough to tell me which sensor has the error. Instead, my test plan in Rheingold is that I have to remove both bumpers and go sensor by sensor through all 10, removing each one and running the test to see if it detects the fault when a particular sensor is removed, then reconnecting it and moving on to the next one.

Hi Roxxor, I have the same ista error but ista say the problem is front left pma sensor with Short Circuit to positive error. How did you solve the problem? Thanks.

Make sure the connection is good in the rem. If so maybe the sensor is bad?
