hey how are you
sorry you having this problem with it
The stability control coming on has to do with ABS pump system. you will need to scan it with GM scanner or equivalent that can communicat with that module
to retrieve fault codes, it could be an abs sensor on one of the wheels, yaw sensor, steering angle sensor , premature activation of pump, if the PCM pick up the fault , it will make it go in limp mode , like reduced power ?
would say the brakes are grabbing or you felling reduced power ?
since no scanner is available Lets try a master reset , if that dont work then we will need that scan so i can be more accurate for you on what is wrong.
Master reset Procedure
1- Disconnect Battery Cables ( Negative & Positive Cables )you can use any electrical wire as an extension if battery cables don't reach .
2- Hold cables Together for 60 secs ,then let go
3- Wait 15 minutes
4- Make sure all doors are closed
5- Reconnect battery Cables
6- Lock & unlock the vehicles using the key from driver door side (if you have a key fob with no blade key, just lock & unlock using the key fob buttons)
7- Enter the vehicle and attempt to start
as fa as safe driving that depends, if the calipers are engaging and brakes grabbing that it is not safe to drive , if only the stability light on and everything else working normal then it is okay .
Please let me know
