2011 Buick Enclave AWD 3.6 V6 135k miles
Hey Scotty
My sister has a enclave that has an ABS light on and Stabilitrak AWD doesn’t work my scan tool doesn’t detect anything wrong. When the abs light is off it makes a constant noise when braking. When the light is on it acts normal. She does have a broken tpms sensor that doesn’t read. I have read somewhere that a faulty tpms can trip those errors. Thank you for your help I also tried unplugging the battery but that didn’t work either.
Is your scan tool able to read ABS codes? An inexpensive generic OBDII scanner won't do it. Bad wheel sensors are the most common thing that trigger these kind of problems but the car needs to be scanned with a professional grade tool for proper diagnostics.
If you know which temps sensor is broken, replace that first.
