When drivin down the highway with cruise on. it will suddenly turn off if i hit a bump or the car has to downshift. First thought was the cruise computer connection. checked it, pulled it out and looked for corrosion, its fine. Pushed it back in and its a good solid connection. What could it be? To my knowledge, the only thing that cancels the cruise is the actual on/off switch and the sensor on the brake pedal. Without pulling the dash apart to check, is that what it is or is there something else i could look at?

there is actually two switches at the brake pedal, one for lights, and the other for cruise control disable, you may just need to adjust a little it might be to close to the pedal and the bumps make it short disabling Cruise control. otherwire it shouldn't disable.

E brake kills the cruise also, it's a really cheap switch so you might want to check that too.

another way to find out which switch it is, is to unplug one, and press the brakes and see if your brake lights turn on or not. if they don't turn on, then it's the other swtich that's for cruise control, if they do turn on, then you unplugged the switch for cruise control.

you say it happens when you hit a bump... so do the tires spin out when this happens, or does the low trac light come on? I only ask, because I know if you lose traction the comp will kill CC too...
