OK. So my 1999 Dodge Ram 2500 4x4 5.9l Cummins has an issue that I cannot seem to figure out and I have been looking for an answer for months.

My speedometer, odometer, compass/thermometer/mpg don't work. My ABS and break lights are not illuminated but they illuminate when I turn the key to "on" without starting the engine...

I have also replaced the VSS and the rear ABS sensor with no luck

Has anyone had this problem or know how to fix it? I would like to know how many miles I have put on each oil change and how fast I'm going

Yes! And the fix is easy too! The clue for me was the brake drums. How do you have pesky ABS brakes using a drum with no tone ring? And: you don't! The data signal is pitched up from the rear pumpkin. On top of the Dana 80, is a small sensor. It had gone bad. Thirty bucks at the dodge dealer and fifteeninutes to install . Good Luck

P.s. Saw you already been there. Off hand I would say you have a wite issue between the sensor and the PCM . Could be a faulty input or output stage to the PCM. Hopefully not.

All fuses are good! I am stumped. I cleaned the connectors by the drivers side fender well too, and on the ABS unit.

If it helps. The original sensor on the rear pumpkin was cracked open...

Still no idea. I replaced the sensor on the rear differential again and still nothing. This is driving me crazy! No voltage drop, no lights on (Except the occasional CEL and the code is the VSS code), I am fed up with this. Can anyone help or is anyone experiencing this?

So I figured it out after changing my rear differential fluid! I have no tone ring! Whoever rebuilt the differential last time just must have forgotten to install it.
