Had pro grille put in 2019 tacoma - warning light

Hello,

I just had an OEM pro grill and OEM garnish put into my 2019 offroad. The collision and lane departure warning lights are on - mechanic says they cannot turn them off and suggested they did not have the right either diagnostic or another reading tool to make them turn off. They assured me it was installed correctly.

Is there something that needs to be done to get those codes/warning lights on dash to go back to normal?

 

I'm assuming the sensor needs to be recalibrated by dealer. What happens if you put the old grill back?
Also I think some people put a washer to angle the sensor a bit.

 

ok, thanks. yes it worked before i brought it in there...

guess i should have brought it to dealer initiallly? you'd think shop would know this to be something they can't finish. i don't get that part.

was working fine when first brought in.
