Which problem occurred first, or did all 3 happen at the same time?
-
Yes. at same time
-
My guess would be a failed ‘speed sensor’, or bad connection to it. Had this happen years ago on an IH, it was that sensor that sits by the drive shaft at the rear of the transmission.
ducnut Thanks this. -
Thanks for your quick response.
I put new a speedsensor but still bad -
CHECK YOUR GROUNDS
-
I am sorry but how can I check Ground
Could you explain about that -
: view active faults
And get all codes from every module. Especially brake ecu
I had similar issue, and harness that goes to front right drive axle speed sensor had a factory crimp connector that corroded and lost connection. You’ll have to take apart about 2-3 feet of the harnessducnut Thanks this. -
Harness is wires.
-
If you don't know how to check wiring, best take it to a shop. Electrical troubleshooting isn't something you can learn overnight.
