ABS and brake light on
Hello folksjust found this site<IMG src=smileys/smiley1.gif border="0"></P>
I have a 99 ram 4x4 pick upwith a 318and 120.000miles.</P>
The abs and brake light has come on, the front brakes are new, the rears are like new,fluid is full. I checked the fuses and relays all good.</P>
The trucks stops good, any thoughts?</P>

Hi John,there are two opportunities: 1. The expensive one (I donīt think so, but its still possible) Your ABS-Module is blown.You could check this on aempty slippery way.Accelerate till 30mph -open the door look at your rear wheels they īre donīt allowed to stop and skidding while fullbreak,they have to rotate while breaking.If they rotate evenat fullbreak the ABS is ok.</P>
2. The lousy one.The ABS got sensors at the rearaxle-drum and maybe at the front calipers.(Depends on your version)Some time the pluglost contact so the ABS-Module get no back-datas and then it says. Caution - NO ABS-Brake.Check this, its my favorit.</P>

Hey Bigcat !! (Lil`Cat?) kind of coward, huh ??<IMG src=smileys/smiley2.gif border="0">You could take a real good buddy for looking from the bed on the rearwheels and if you make a fullbreak heīs bashing into the cabin. <IMG src=smileys/smiley11.gif border="0"> Sound thatīs better ?? Mikel</P>

RE: ABS and brake light on
I've got a similar if not the same problem.
The ABS and Brake light both illuminate when my speed reaches about 40MPH, then they stay on until I turn off the truck. When I start it up again, the lights are off until I'm close to the 40MPH range again.
I already replaced the RWAL sensor on top of the rear differential, I still have the same problem.
Being curious, I disconnected the wire from the new RWAL sensor as another test. When disconnected, both lights turn on and stay on as soon as the truck is started.

RE: ABS and brake light on
I also have the same problem my ABS & Brake light stay on in my 1999 Dodge Ram 4x2, I also noticed that my odometer start reading after I hit 20 to 25 MPH. I did some research and I found out that it can be my speed sensor. I am going to hook up a diagnostic reading this weekend. I will let you know what I find out.
Thanks

RE: ABS and brake light on
JDodge00,
I can almost gurantee that your problem is the speed sensor on your rear differential. I had the exact same problem in my 2001 4X4 Ram 1500. The speed sensor on the rear differential is responsible for the speedometer speed as well as the RWAL. At least this was the problem with my truck...The part was 33 bucks and really easy to change...
