Dash PCS Light

Right?? Reading this I thought it was just me and the Pro Grill with the garnish that had the problem, seems like people with factory emblem grill have the same issue, unreal.

 

For what is worth if your tire pressure is too low it'll do that.

 

I just bought a 21 trd pro I’ve had for 2 weeks with 12k on it. After reading this thread I think the guy that said the windshield sensor and radar AND tire pressure are correct. My lights been coming on every morning at 630 am. It’s 28 degrees out trucks covered in frost module on the grill is immaculate tire pressure is 28 when I start it up light stays on till The glass is frost free and the tires have heated up to 31-32 which at this point I’ve went 5-6 miles. Maybe it’s a combination of all of it (which would make sense) if any variable is missing you get the light. Never seen the light unless it was frosty. Never have it when leaving my garage. My first Tacoma and post. Hope this helps.

 

Interestingly enough, this is actually covered in the manual where it says the light may temporarily illuminate in extreme hot or cold weather. Mine will do it occasionally for a few minutes, usually when the temps are hovering around 20°F but not when it's colder or warmer.
