Pre-collision system malfunction

So I added an ARB front bumper and winch. My front collision avoidance system doesn’t work now. I expected this since it’s partially blocked. This was no big deal initially, as I was still able to use my cruise control, just without the adaptive portion working. Now I get a message that says to see my dealer, and that the collision system isn’t working. I tried to turn it off after the error popped up by disconnecting the battery for about a half hour, this didn’t work. I also tried to disable in the menu and this didn’t work either. Obviously this is outside the warranty. Any thoughts before I take it into the dealer?

 

Get an sr5 grill and move the sensor up out of the way of the bumper?

 

Disconnect the sensor?

 

not yet

 

Disconnecting the TSS causes same error warnings.

 

You can set PCS to default to off (by remembering the last setting) using techstream or carista. TSB 0059-18 tells how to do this with techstream. Carista is similar.

 

I was looking at an Arb bumper until I read the small print on their site about “some” trucks having the problem with TSS. Leads me to believe it is because the pro grill has the sensor so low, I would have to think GreyBaldTaco is right, get a grill that moves it higher

 

Put a monkey face sticker over the warning lights.

get the toyota grill that keeps sensor behind the logo. Mine works fine with stock grille and arb.

 

I have a stock SR5 grill and sport/OR grill..... Wanna trade.

 

A piece of black electrical tape over the idiot light. Really? A company builds a great vehicle, you goof it up by changing their work, and want to take it back to them to fix it? Be prepared for them to send you away.

 

Damn.. get some coffee. I don’t see where he wanted to take it back to dealer under warranty

 

+1

Of course @mojavejohn will need to the take the bumper off again to swap grilles...

Nonsense. The dealer would be pleased to quote you on a diagnostic fee out of pocket, and refer you to their parts counter for a non-Pro grille at retail pricing.

 

Yeah, I hope it doesn’t come to that. I love that grill.

 

PERFECT!

 

Is techstream or carista a computer to hook up to the OBD port to access the computer?

 

Techstream is a done with a computer and an OBD cable, carista is done with an app and a Bluetooth OBD adapter.

 

I’ve been researching them. It looks like I should get the carista, as I only have Apple products at my house. Have you used the carista? Is it pretty straight forward? I’m barely tech savy.

 

I have had carista for a few years and it is super easy to use. I have android and use a cheap bluetooth adapter from Amazon. The carista adapter works with ios and comes with a month of the paid app features.

 

Right on. I'm going to order tonight. This is just the info I was looking for. I was planning on going to the dealer tomorrow. I don't have to for now. I'm guessing that I should be able to use it to turn off the stupid seatbelt chime as well? What have you used it for?
