Hi Guys I have a vauxhall insignia that refuses to start. I have fault code U0140-71 lost communication-invalid data from electronic brake control module to body control module. I have checked all power & grounds. I have also opened the wiring loom looking for bad wiring. I have replaced & reprogrammed the BCM.I have 60ohms resistance at the DLC plug so it looks like the GMLAN system is good.
I am running out of ideas
