2008 4x4 AT. While on a long trip my ABS, CEL, VSC OFF, VSC TRAC, and BRAKE lights all came on intermittently. By the time we arrived home they were on all the time. Shortly thereafter the speedometer stopped working. I researched on here hoping to find a solution. So far I have cleared codes to make sure it wasn’t a fluke, no change. I change all 4 wheel speed sensors, I changed the stop light switch, no changes. The codes have been somewhat random depending on the day I hook up the code reader, but 3 are consistent. C1223 “malfunction in ABS control system”, C0215 “Left rear speed sensor signal malfunction”, and C0210 “right rear speed sensor”. I also have checked the wheel bearings and they seem fine, I have traced the speed sensor wiring the best I can and have found nothing too obvious there. I am unsure how to test the sensors. I also found that the Right Rear Sensor was dirty and wet, so i replaced both rear axle seals. They are both clean and new now. I am at my wits end with these lights, and would like to know my speed! Also may be important to note, the odometer is not working.
