VSC,TRAC and engine light turn on when rear window defrost is turned on.

(2008 Toyota 4Runner)
I have been having this problem since 2011 when the body shop had to repair the roof from severe hail damage. The body shop attempted to diagnose the trouble and had the vehicle sent to electrical shop and they were unable to solve the problem. I too read the engine code when light comes on with right rear bank O2 sensor. The rear defrost has nothing to do with emissions. If the defrost is turned off, the lights will turn off after several restarts and driving around the city. Please help.

Hello,
This issue being around for 6 years without further complication shoots down my confidence in an electrical control unit failure.
This really will take a good technician to handle the issue, and there is a possibility that your vehicle never even went to an automotive electrician, as they tend to be specialists.
The shop that performed the work should have, at the very least, sent the vehicle to some reputable automotive electrician or technician, or paid for your shop of choice.
Let me know if you have other questions, otherwise, here is a list of certified shops for your convenience.
