    Just got a new travel trailer for my 2012 Tacoma DCLB Sport w/towing package. Shortly after the RV place hooked up my brake controller, the TRAC OFF light comes on, as well as the check engine light. Neither will go off? Also I no longer have Cruise Control? The RV dealer was stumped, they said take it to your Toyota dealer, let them figure it out. They did offer to pay any bill that the Toyota dealer would charge. Any ideas? Thought I would put this out before dropping off at dealer.
    Thanks.

    sounds like possibly a blown fuse with not having cruise control.

    ABS/Trac/VSC issues will command a CEL.

    Cruise not working makes me think it might be an issue with the brake light circuit... ECU thinks the brake light is on?
