Pre-Collision System Malfunction

I figured I'd throw up an updated post regarding this issue.....So, After having a lift/tires done on my 2018, I had the check engine light come on and the message "Pre-Collision System Malfunction Visit Your Dealer." So, Today I went ahead and visited my dealer only to find out that, according to them, there is no fix for the issue. The only fix would be for me to remove my lift and put normal size tires back on.....I laughed and said yeah I think I'll just deal with the light being on. With that being said, they also informed me that the warranty for anything dealing with the pre-collision system is now voided......oh well I don't need it anyway. That trip cost me a $100 diagnosis/labor fee....I should have just kept ignoring it!

Dealer: Diehl Toyota of Butler, Butler, PA

 

Pretty sure people have had them recalibrated for a lift, you might want to call around.

 

You can try getting a pro grill (or decent knockoff) and a oem TSSP sensor garnish and see if dropping the sensor down a few inches with it may get it to work again without error.

 

It's BS, your lift doesn't void a warranty and many people have had it re-calibrated at the dealer.
