TSS Issue after Wiring in Lightbar

After my buddy and I wired in a lightbar, my TSS now malfunctions immediately. Anyone come across an issue like this before, you 2018+ owners?

I have an aftermarket grille plus some other mods, and I would hate to take into Toyota.

 

How about some more details

Like how you wired it, where the light is...

 

Add pics.

 

How about a pic of where its mounted?

 

I've been using the grille for months, and the TSS isn't a issue. It's only with the coincidence of once we wired in the lightbar.

 

The TSS is wired the OEM way, and the lightbar is using a standard harness a lightbar uses (relay, positive/ground, etc) and is going thru the firewall and into the cabin with a switch. I'm not sure how these things are related in any sort of way, unless something was pulled or blown, or whatever.

Maybe I'll better off just searching for TSS stuff on the forums somewhere.

 

What error are you getting?

Is the light bar sticking out where it may interfere with the radar? They mention in the manual that bull bars may interfere.

If you disconnect the light bar power is there still a problem?

If you remove the light bar but leave it wired in is there still a problem?
