So my 2006 yukon Denali started having an issue out of the blue, everytime I depress the brake pedal, service ABS/Stabilitrak and both corresponding dash lights illuminate. I am getting 2 different codes read from my snap-on Solus ultra. C0131 and c0283. C0131 is the pressure switch on the modulator. C0283 I am assuming is a secondary code due to the first code saying the VSES mode switch malfunction, probably because it can see it is not getting a response. The odd part is I replaced the pressure sensor with genuine GM part. No success. The next odd part is while scrolling through the data display on the solus i was able to see the brake switch, (while depressed) seemed to toggle from on-off-on-off and so on... not an uncommon issue for these trucks so I ordered one from my local Napa, installed and still to no avail, except now on the solus when the pedal is depressed I get zero response. I have witnessed part store products fail out of the box so I called the local dealership and ordered an OEM switch and will pick it up tomorrow and see what happens. Also, brake lights work as they should, no electrical components (fuses/relays) seem to be malfunctioning. If anyone has any insight please chime in!
