I've got a 'service TPMS' message on my EVIC and the TPMS is showing no data for the left hand rear tyre. I've checked all tyres, they are correctly inflated, so today I did a tyre rotation and the same location (left hand rear) is still showing no data even after a drive so the system can reset. This leads me to believe the problem isn't the sensor in the wheel but the signal pickup/trigger on the body at that location. So my question is, where the hell is it located and is there a wiring loom I can check for damage/correct connection?
