I have tahoe 2009 , 5.3 L engine , the cruise control is not working .
I have suspected the brake pedal switch , because when I scan it with my maxisys
Mini 905 , I have found that the BPP prake pedal switch gives applied on cruise live data and not changing when I hit the brake pedal .
But on another hand the BPP changing when I see it on engine live data .
Why the same varible have two different values ???
Could you help me in this regard
