when i do the cluster test with the trip button i dont any codes and it does the full sweep for all gauges.
after plugging the cluster back in the no bus went away but i still have my ABS, AirBag and Brake light on. Im going to drive it around and see if the no bus comes back

 

2 or 4 wheel antilock? Speedo works properly? Correct??

 

Not sure about the 4wheel abs this is the only connection i have upfront and its on my front axle, other than that i dont see any other connections or wires coming from my front axle or brakes.


At first the speedometer was not working then it randomly kicked on and i was suprised since i couldnt ever get it to start marking my speed, it has a few moments where the needle would drop but then it would pick right back up this would only happen on bumps. Also my mileage odometer started working aswell… And the “no bus” hasnt came back yet

 

That's the cad, and 4x4 indicator switch on the front axle. You have Rear Wheel ABS.

If you are seeing speedometer issues, replace the rear wheel speed sensor on the rear axle. Air Bag *might* be related to that as well, but, one thing at a time.

 

I have already replaced that sensor, as well as the sensor on the transmission and my abs module. I still have warranty on the two sensors I replaced, i got them from autozone with a life time warranty

 

Could my cluster be bad? When I disconnected the cluster and plugged it back in the “No bus” was no longer there

 

Started up my truck to let it warm up before i headed into town and these are the only 2 lights showing up, Also reads my tank is empty but i know i have half a tank

 

After driving it around for about 30-60 min the gas light went away and it started to read fuel correctly, suddenly the Abs,brake, and check engine light come on and speedometer starts flickering again… a couple minutes later I completely lose the speedometer/odometer. Keep in mind that i still dont have the “No Bus” light

This is the same code ive been getting from the beginning and I’ve replaced both of the sensors already, ive chcked the connectors for corrosion or any sortve pinched or split wire, i even checked voltage and ohms with multi meter

feels like im going in circles

 

Tach is at zero, as is oil pressure, volts are reading very low. Is the engine actually running there??? If it is, see what voltage you are getting AT the battery. Is the alternator trying to charge it? Or is that gone too?

 

no the engine wasn’t running in that picture, it was with the key ON so i could show the lights, theres a fresh battery in there just got it this month, alternator works fine.

i only got to drive it about 3 miles before everything started to mess up again as u can see my odometer only went up 3 miles
