Hey guys.

So the problem has been there since i got the truck 4 months ago. ABS + BRAKE light shines up when i pass 40mph.
Did alot of reading and ordered the rear axle sensor..

Few weeks later i got the sensor and replaced it with no change, still ABS + BRAKE at exacly 40mph.

Did some more reading and ordered a ABS module unit, replaced it.
Now its more random, sometimes i wont light up at all and sometimes at 40 to 50mph.

Wierd thing is if i do a quick restart while truck is rolling at 30mph~ and the ABS+BRAKE lights turn off it wont come back til i stand still and restart the truck.

Any ideas what the problem is? Its a rear only ABS.

 

do you have rear wheel or all wheel abs? if you have a scanner capable of reading real time data, set it to display wheel sensor data and keep an eye on it while driving. if there's a sensor issue you'll know. i went through 3 sensors, 2 were bad right out of the box, before i finally fixed mine.

 

Its a rear only ABS. Well since The speedometer is working there gotta be something wrong with the ABS system. Problem is i cant find anyone with a scanner for ABS.

 

What year is your truck?

 

1999 4x4

 

You need to read codes, and see what it is whining about. If you got a cheap, aftermarket sensor, that may still be the problem.

 

Gonna call the dodge mechanic tomorrow!

I did some more digging and since i got the truck its been equipped with a Tekonsha envoy, its some sort of towing brake?

Was gonna order a new brake switch and see the picture, someone has cut off half of the wires?

 

That would likely annoy the ABS system. Probably a few others as well. If you have the service manual, take a look at where those wires are supposed to go, and see if you can find the other ends....
