All light in the dashboard is on

 

 

1- Check Engine Lights</SPAN>

 

2- ABS

 

3- Handbrake

For the Check Engine ( I change the knock sensor and O2 sensor ) it’s gone then it back.

You have SERIOUS problems!

 

I suggest you take it to a GM dealer for service.

 

The "class 2" problem has to do with a computer network. EVERYTHING on the vehicle needs these computer networks to operate properly.

 

This is advanced troubleshooting to track down these problems.
