    It was open circuited wasn't it? Can you actually buy that part from GM, or is it part of the switch?

    Good thing it was that, because the next step after checking that and the switch itself was new EBTCM.

    Ya it was a open circuited, i got a new one from a electrical part store, i just unsolder it from the connector, its not part of the switch itself but its on the switch connector

    i took it with me to the store, they gave me a new one, did look different but hey it works so who care's, GM as dealer or part house doesnít exist here anymore, they didnít survival
    So its getting real difficult to get parts for GMís hereÖ

    I think the function of that capacitor is to supervise the wiring between the switch and the EBTCM. It leaves voltage on the circuit when the brake switch is open but not enough current to light the brake lights or trip the cruise control module. If it wasn't there and the wire broke the EBTCM would never know. Its not mentioned anywhere in the service manual other than the wiring diagrams and its not in the trouble shooting section for that code. I've often wondered how how the car knows if the brake switch circuit is open, since thats its normal condition, unless the brakes are applie. It misleads you into thinking the switch is bad, instead of the wiring (or in this case the capacitor), its kind of a bad name for that particular DTC.

    That was a good call Mark, I will have to put that one away in my fixit file for future reference, I too looked at the diagnostic routine and saw the replacement of the EBTCM as next on his list, I was wondering what the problem was when he mentioned that he tried another one. Thanks for the tip.
