Buick Repair Questions? Ask a Mechanic for Answers ASAP
I have been a professional master mechanic for over 35 years and am happy to help you with this.
What you are going to need to do first is have it scanned for codes in the ABS system. This type of scan tool is different than one used for engine codes. You might find a parts store that will be able to do this, i know that all of them can do it for the engine codes.
Most likely it is a faulty front ABS wheel speed sensor but you wont know which side because there is one on each side and the code will tell which side is at fault.
If you have more questions just reply.
Any further questions?
VERY smart move my friend!
Just make sure it can read ABS codes like i mentioned because just the regular engine code reader doesnt have that capability.
Once you get it you should clear all codes and drive it and after the light comes on grab the first code that sets.
