VSC OFF, VSC TRAC, skid, and check engine annunciators all just went on - halp!

They all went on simultaneously, about 10 minutes after the maint req annunciator went on (truck IS at a scheduled maintenance interval -- so the maint req light was expected -- the other annunciators were not expected). Another thing also, I just did the 400W anytime mod with added interior AC outlet, which I have been using all day to power my laptop. Not sure if the VSC stuff is related to either the 400W mod or the maint req interval, or if it is just coincidental. Thoughts?

What/how should I troubleshoot?

Thanks. I never noticed the VSC/TRAC lights when the CEL has gone on before, but then again there are a lot of things I don't notice.

 

2006 had VSC and TRAC ??

 

So the VSC, skid, CEL, and TRAC annunciators that were on before are now mysteriously no longer on, after three short trips to town. Only the maint req light remains on. Phantom illness I guess? Or intermittent problem? I drove thru a couple of muddy puddles earlier today so maybe that caused a false alarm somehow...?

 

Whippersnapper has the answer. Pull the codes to find out what's going on.

If you don't have a code reader yet, time to get one.

Whip, I was just giving you guys a hard time -- after you answered my initial OP, I kicked back and enjoyed the rest of the gong show that ensued
