No speedometer, odometer, and ABS light on
Okay, my Ram 2500 with a Cummins 12 valve has no speedometer, no odometer, and the ABS light is on. I pulled the ABS sensor on the rear differential and it ohms out at 1.87kw. That makes me think the sensor is good. Seems like it could be the wiring, a bad ground, the sensor, or the computer. Any advice on how to narrow down what the problem actually is?

Is there a speed sensor in the back of the tcase? On most 12valve Dodges the speedo, odo, cruise signal is taken from there... the axle sensor is dedicated for ABS. Maybe it changed on later years. Not sure.

speed sensor is on the tcase if you have a 4x4 (fill out your sig) and on the trans if not. Abs is not related as far as i know, that could be sensor on the rear pumpkin or wheel speed sensors or the controller. good luck!
