Yesterday I took some time to run some tests on the CAN - it is a long video where I disconnect everything from the CAN and one at a time connect an ECU and restest the voltage, then disconnect that and connect another one etc etc....so it took a short while - the vid is abot 37 minutes
TLDR: All seems well until the EPB which is when the Voltages do something different instead of 2.43 (HSCAN L) and 2.53 (HSCAN H) with everyhing else it goes to 2.35 (HSCAN L) and 2.61 (HSCAN H) when it is plugged in. I tried another EPB module and the same thing happened....curious!!!
I also checked the connections behind the Pax rear wheel and they are super clean and the wiring is intact.

And they look fine - I wonder if it could be the wiring to the EPB?
And also, how could a dodgy EPB affect the Yaw Sensor considering they are on a separate network and never the twain shall meet??
All earth points check out too and the EPB works well and no issues to report???
Other than this yaw Rate Sensor reading the car works well - obviously I have no Terrain Response or traction control and warning lights on the dash.....and a couple of modules report 'Invalid Data received from the Vehicle Dynamics Control Module' because the Yaw Sensor readings are so ridiculous I am getting to the end of my knowledge now
Confused dot com comes to mind!
