Parking assist/support malfunction

Shop installed CBI covert bumper and DD amber fogs on my 24 Pro. All connections look good and solid but now have the parking assist & support brake malfunction warning lights. I am headed back to Pacific Upfitters to have everything double checked before contacting dealer.
Known issue when grille is removed? Do these errors need to be cleared by dealer?
Thank you!

 

I was able to clear the faults with Carista, but only for a few seconds then they reappear again. Guess I do need to go to the dealer and have them reset faults or recalibrate sensors. Bummer!

 

The frustrating part is that code can be thrown for almost any reason. It’s likely something needs to be calibrated after the bumper but would just double check all connections as step one. Can always try to reset the battery as well.

Have the exact same code after taking off my front bumper for like the 5th time doing my alpharex headlights today. Either the truck didn’t like where I put the second fuse or somehow knocked loose a sensor on the bumper is my guess but it could be literally anything that throws that code

 

Were Toyota dealer able to recalibrate your sensors? I'm having the same code appearing after installing a bumper.

 

Yes, but it was due to a faulty harness. Toyota installed a new harness under warranty. Everything is fine now.

 

Ah I see thanks, the shop I used IronRigs4x4 installed a lot of bumpers on these tundras and they said this is the first time they had one threw code. Truck is at the dealer now we'll see if it's also a faulty harness or if the sensors just need to be recalibrated.
