Help! VSC dash light on
 
Hello all,

I was hoping I might be able to get some info or guidance in troubleshooting the VSC dash light that's been consistently illuminating the past couple of weeks. The light never tripped prior to the car's battery dying. When the battery died, and the car wouldn't start, I disconnected the negative terminal, and charged the battery. Upon charging, the car started, but that is when the VSC light started illuminating.

I have an OBD II reader (craftsman) and saw that there was a failure to start code which was probably when I tried to start the car with the weak battery. There are other readiness codes (which I will have to get from my phone if you guys think they may be relevant). I cleared the failure to start code, but the light is still illuminated.

Anyway, I was hoping someone might have some insight, or be able to point me in the right direction. I've done searching, but didn't really find anything too helpful/relevant. Any help is appreciated. Thank you in advance!

It seems like I read there is a complicated process to turn off the VSC that only shuts it off for that drive cycle. Maybe if you did this process it would reset the system and start up correctly the next time you start the car. Do a search to see if you can find what this process is to turn off the VSC. Think of it like a reboot of a Windows machine. I have no idea if it will do anything but this is the only thing that is coming to my mind right now.

Also, make sure your alternator is outputting the correct voltage. I've seen a bad alternator cause lots of dash lights to come on. You should be getting about 13.5V across the battery terminals when the engine is running.
