Message: After reviewing allot of good post from my search I am trying to clarify Sensor or HCU problem.
ABS and brake lite come on after reaching speeds over 45 - 60 mph. Below that the speedo works fine and the lts do not come on. After a shut down the lt clears.
One guys said the dealer changed the HCU and reset the code. A few others said the Brake lt switch behind the pedal worked for them.
Is there something in the description of my problem that norrows it down better?
Thanks

Message: I recall the same problem with my 99 5.2 cc. It was the speed/abs sensor that is located on the rear end housing. It cost $35 and worked for me.
Message: After reading all the post on this I tend to think it may not be the rear speed sensor on the rear diff. Most stated with this grip it did not fix the problem since as far as I understand it the speedo and the abs/brake lites have issues.

re-read my previous reply, if the speedo isn't effected when the brake and ABS lights are on than most likely it's not the 2 sensors you mentioned, it may be the same as what was wrong with mine, the HCU ( hydraulic control unit) it controls the ABS, dealer replaced mine in 15 minutes and it cured the problem. The code for the HCU came up when they checked it also.
I know other people on my previous post about this subject mentioned a speed sensor could be bad but they said the rear-end speed sensor will effect the 0 to 15 mph reading on the speedometer and the sensor on the tranny ( if bad) effects the mph reading at speeds over 15. service writer said that's one way to tell what sensor is bad
I am not seeing the speedo problem and this is why I ask if someone can clarify this.
I may just start changing things and hope I get lucky but was hoping I could narrow it down.
Thanks for the input!

Thanks but that does defeat the purpose of this board. If know one know's or can add anything further, I may try a thing or 2, or just take it to the mech but that is so inconvienent.
Thanks for the suggestion!

Message: The speedo may not be affected. There have been posts on a number of Dodge forums where the speedo was not affected when the rear sensor went out or the speedo acted up a different speeds. My speedo never stopped working.
Message: I should update this post. I finally had my mechanic trouble shoot this problem and my error was a brake light switch error code. All they did was reset the the code and I have not had the problem again.
