I have 2002 sr5 4x4 and recently the VSC OFF, VSC TRAC, and CEL (check engine) lights have all been on. I searched and found people with the same problem but with NO CEL, so I think my problem must be different. I tried pushing the center diff lock button on and then off, but that didn't change the lights. The car drives just like normal. I did just set the alarm off by slamming into my door, but that doesn't seem like it would make the lights come on. I don't really know anything about codes or electronics, so I have no idea what I'm talking about. But that check engine light worries me... Any help would be appreciated! :thanks:
