2013 dash warning lights

Had a professional installer mount a 2 way radio for fire Dept; since the install the “check engine”, and “trac control” lights are lit, and the “4Lo” indicator flashes.
He tried pulling the radio and connection but lights still active.
Anyone had this experience, or know how to clear it?
Tried the online cures for the engine light with no luck. I’m thinking I’ll disconnect the battery to see what that does, but thought I’d throw a Hail Mary to the Tundra cyber world
thanks!

 

Sorry you're having this problem, I assume you don't have a scanner? I bought one for about 80 bucks 10+ years ago that has paid for its self 100X over.

If you don't want to do that I suggest going to one of the chain parts stores, most will scan and clear free (hoping to sell you the parts indicated)

Good luck!

 

Pop the hood, open fuse box and check /test the ecm fuse and dome light fuses.

I believe they are 7.5a
