2004 Ram 1500 QC SLT Lone Star ABS/Brake lights are illuminated. The build sheet list, "4 WHEEL DISC RR ANTI-LOCK BRAKES" (not 100% sure what that means). I have replaced the speed sensors located on the rear end, both on the transmission and the one on the driver's side front hub. After the rear end sensor was replaced, the speedometer started working again although it does bounce around a little. not sure if its related but seems worth mentioning is that the cruise control is erratic and seems like its constantly chasing the set speed. Both indicators light up with a chime at or about 35-40 mph. OBD2 codes are P0442, P0456, and P0430. (Unrelated emissions issues). Not sure how to proceed. Any insights at all will be greatly appreciated. Jc 07

 

You still have an erratic speed sensor issue.
