Hi all
I have been reading the post and no one seems to have this issue. Like everyone else, I have ABS activation at low speeds. This was caused by a faulty ABS sensor on the RT Wheel. We went to Rileys and got a replacement. It went from not so bad to activating and pulling to the right. I am fortunate to have a Maxsys scanner and I drove the truck with monitoring the live data from the speed sensors. Here is what I saw
RT wheel sensor STOPPED reporting at 8.2 MPH
LT wheel sensor STOPPED reporting at 3.75 MPH
Rear-wheel sensor STOPPED reporting at 3.75 MPH
Moving forward all sensors reported equal speeds after 8.2 MPH
Wow! interesting.
I replaced the LT sensor and the truck still got low-speed activation but the pulling stopped. Now both front sensors stop reporting speed at 8.2 MPH and the rear stops at 3.75.
Ok, so I replaced the rear sensor and the results were still the same.
Next, I thought that the sensors are aftermarket so I ordered sensors from chevy and installed them. test drove the truck and guess what, they also stop reporting at 8.2 MPH, the rear at 3.75 MPH, and the ABS activated at low speed.
Being ex AF we would sometimes use a broke plane to cannibalize parts of to fix a plane that need to fly soon, so, I had access to a same year truck and I took the sensor off that truck and reinstalled the old LT sensor. Took it for a test drive monitoring the sensors and guess what,,,, the problem went away and all sensors stop reporting at 3.75MPH and the truck works great.
WTH!
can anyone explain to me what I am seeing? The ABS pump was replaced from that other donor truck to fix the original issue of the ABS system. I will have to put the donor truck back together and I need to understand these bizarre findings. otherwise, I will have to scrounge a sensor from a salvage yard.
Anyone, please help
