Code P0719


Recommended Posts

Posted

Hey guys I'm getting this code on my 03 Sierra that I just bought.

 

P0719 Brake Switch Circuit Low Input

 

Cruise control does not work, and I can put it into gear without pushing the brake. Brake lights work fine.

 

I plugged a brand new GM switch in today, and I could still just drop it into gear. What else could it be?

 

Thanks

Have you tried replacing the brake light bulbs? Sometimes as the bulb ages the resistance value changes and will freak out the cruise module.
