So this is how it started my 02 ram 1500 the brake and abs light came on and dinged every time I shifted so I looked around and found out to replace the sensor on the rear axle I did and now it comes on when I first start the truck then one of 3 things happens it ether works fine for the day the light come on and ding every couple seconds and don't stop till I restart the truck or they stay on an spedo quits working I have replaced the sensor twice I took the truck the lesscwabs they scanned it found no codes took it to the dodge dealer they scanned it and found no codes and had no recommendations for me I checked the sensor cleaned the connection to it it still does it and seem to be the worst after a night of heavy rain or really cold mornings if anyone has any ideas I'd appreciate it
