]Hello,

I recently purchased a 2009 hhr LS. The brake, abs and traction lights are on.
I went and got the codes on it today. P0573 was the code that came up. Brake switch circuit High voltage was the reading. The part is $8 at auto zone. Simple fix. By the way if you're having these 3 lights come on AND your cruise control is not coming on then this is the reason!! It tells your computer NOT to activate cruise control because the sensor will not detect the correct speed and could cause you to go too fast and cause an accident.

 

Thank you , Candace and welcome to the site.
And for future readers here’s that code explanation

I’m happy to see your problem was resolved.
