Light bar tss light on

I am a new Tacoma owner 19 Trd sport with the adaptive cruise control. I recently installed a KC hilites double row light bar with the Cali raised brackets behind the grill. The brackets are nice and adjustable so i mounted it in a perfect position so it would be close to the grill and had room around the bar so it wouldn’t interfere with the radar sensor. 10 miles into the first drive the PCA light illuminated saying PCA off. Tried disconnecting battery, driving for a few weeks to see if it would go off and nothing. I removed the grill and lowered the brackets and light bar as low and far back as possible. The light never came back on and all is well now. I also have the one pro grill with garnish installed. I hope this helps someone if they are considering a light bar and have the adaptive cruise control.

 

Was it only when the light bars were on? It shouldn't really do anything if you just installed it. Maybe issues when turning on the light messes with the sensor.

 

Glad I have a '16

 

yep. Adaptive cruise would be nice, but could care less for all the other crap.

 

No it happened when the light bar was not in use. I also removed the fuse from the harness to see if that had an affect on it. It was just the proximity to the sensor. I saw a post somewhere online from Toyota that said nothing should be installed in that area.
