LED bar install now pre- collision and lane departure are malfunctioning

Had a friend install LED bar now the pre-collision system and lane departure alert are malfunctioning. Should I just take it to the dealership? I do have warranty... idk I think I made a mistake :/

 

Have you tried crawling underneath to see if any wires were cut or sensors blocked?

 

Undo the bar and see if that fixes it. Where did you mount the bar. May be blocking a sensor or you could have tapped a wrong wire

 

Yup I think that’s what he did I’ll take it back to him because the pre collision sensor is not plugged into anything

 

I’m trying to do that now but Florida is a constant shower lol

 

I think that was it. Found the plug connected it. But does that front sensor also tap into the lane departure alert sensors?

 

Fixed it... thankfully
