SOURCE: ABS Problems

Gary,

Just went through this problem with my Dakota as well. This is a very very very common problem with the Dodges. First things first. Replace the Vehicle Speed Sensor on the rear differential. Cost around 40 dollars at your local auto parts store or even from the stealership. Its easy to change as well one nut and off comes the bracket then the stud comes off and then you can take out the sensor. They big key is here to be VERY careful pulling out the sensor or you will break it off in the housing. You will need to slowly turn and pry it out with a small screwdriver (as there is an Oring holding it in). Reverse the process to install the new one. After you get the sensor in, reset everything by pulling the negative off the battery and leaving it off for 30 min (some require less time but 30 min is safe) to ensure all is reset. Hope this helps you.

Sincerely,

Jeremy

SOURCE: speedo not working and tc and abs lights on

under your hood there is a abs pump, it make the pressure for the abs to work and when the system is faulty they vibrate and make a long steady noise when you first turn your car on, sometimes they even vibrate, stop then vibrate again a few seconds later. while this is annoying and semi embarasing u can use your brakes w/out abs. or you can replace the unit for 600bucks plus labor at the shop. its a easy fix if u wanna do it yourself. it takes 1.hr in labor plus you can find the part at the junkyard for 250. i hope i was helpful.

SOURCE: Speedo suddenly not working and two warning lights

If the ABS (and likely the traction control) light came on at the same time that the speedometer stopped working, you likely have a faulty wheel speed sensor at the right rear wheel. You can test this by swapping the two rear wheel speed sensors (ABS sensors). If the speedometer then works (but the ABS & Traction control lights stay on), replace the sensor that is now at the left rear (was at the right rear). If no change, you may have a fault in the ABS & Traction control - control unit.

Speedometer not working on ford escort 1999


speedo works off one of the front wheels depending on your country, the signal goes to the abs unit then out of the abs unit to the speedo. the speedo could be at fault. or the sensor but if the sensor is at fault the abs light would be on so first i would check the single wire from the abs unit, clean the connections, the signal is a pulse. the faster the pulse the faster the speedo goes..

Can a bad range sensor cause my spedometer not to work and incorrect gear ratios on 2 3 and 4? if now what could it be?


the abs unit tells the ecu and the gearbox the speed and when to change gear if this is not working it could be one of these two the abs unit or the wheel sensor, the wheel sensor there are 4 of them in uk left front wheel is the speedo signal sensor, if abs system is dead i.e saying there is no faults or even connecting to a reader there is a fault. to determine the gear the gearbox needs the signal range sensor incorrect means there is a signal coming to the gear box but its erratic.

Speedometer not working.


No it does not. The speedometer uses the VSS (vehicle speed sensor) This goes to the ECM then the instrument panel,the transmission control also uses this sensor

1997 GMC Jimmy braking problem


the abs control unit controls the speedo (tach) also tells the cruise signal. abs should be fixed or replaced for any of these to work properly with the abs system not working you have no signal to the ecu to say what fuel air mix is for the speed you are doing and will think you are idling.

Speedometer not working


speedometer get speed signal from ABS. ABS and DSC are two functionality in same ECU. 
You shall read faults from ABS/DSC ECU.
Most frequently, there are problems with speed sensors on wheels.
With ignition on, you shall measure voltage on both wires (- pole of voltmeter shall be connected on vehicle ground). You will see one sensor without voltage supply. This will sensor with problem. you can, for check, change sensors on same axle (left and right). 
Switch ignition off, and on. 
If voltage supply missing will go on another side (with faulty sensor), you will be sure that is problem is sensor.
