Ok, here is my situation and in need of HELP from expert folks here.
I have a 2014 ram 1500 big horn. I have front and rear park sensors. Over the weekend, I kept getting "Service" light up on the park sensor screenn for the rear sensor. I went ahead and got a new OEM jumper harness from ram parts department and 4 new sensors from 1aAuto. Everything is working great when in parked or backing up. But as soon as I put it in drive and goes above 8~10 mph, the truck I believe tries and turn off the rear sensors. Immidialty I get a "Service" for park sensor rear. The button would light up and I can't enable it again. But as soon as I put it into reverse, the system comes back on as normal. I put a reader on the OBD and it read B1295-12, B1296-12, B1297-12 and B1298-12 which indicates all 4 sensors has a "PTS (Parktronics) sensor 8 - circuit short to battery. does this mean I have a bad park assist module or does the 4 sensors from 1aAuto isn't compatible with ram system; even though they said it would be? HELP! Driving me insane.
