TSS/Pre Collision System Malfunction....

Good luck with the repair! Thanks for keeping us informed.

 

Did they give you and ETA on parts? I am going to dealer tomorrow with the hope that the error comes up when I go there. Just not excited about leaving my truck with them if they will have to wait for parts.

 

My PCS went out but first posted a tow error, will the tow controller going out cause the PCs to fail? I cleaned the sensor and reset the battery so I’ll see if it comes back.

 

Looks like I am making a trip to the dealer. 6400 miles with no lift and a stock grill.

 

As of right now mine hasn’t come back, but I did disable it, so seeing if it’s really fixed after I cleaned the Toyota badge and reset the battery. Try cleaning your badge and make sure the windshield is clean In front of the camera.

 

Will do thanks…

 

So as of my 30mile drive to and from work, after cleaning the badge with the system engaged…good to go!

 

Thanks again! It just needed a good cleaning and I didn’t even disconnect the battery. I am a little surprised how a fairly clean truck would cause a malfunction. I washed it two weeks ago and was used very little.

 

2021 TRD Pro having the same issues. Light went off 3 miles after taking this picture

 

So I've just had the "collision warning sensor" light came on today saying it's off when it shows ON in my settings. I've had my 2018 crewmax for about 3 months now (2nd owner), and had no issue up to this point. I did however wash my truck very thoroughly last night and I also swapped out my 2018 grill (circular toyota symbol) to the TRD PRO style grill (all honeycomb w/ toyota lettering) about 3 weeks ago. After reading these threads I'm hearing that the issue could be one of a couple things?

- moisture on sensor
- moving the sensor itself
- snow/heavy rain (Both of which happened this week)

I'm not sure what to do to try and reset the light on the dash...?????

I have an extended warranty through the Ford dealership I bought the truck from, but I'm afraid they won't honor that since I swapped out the front grille.
I read something in here about disconnecting the battery for a bit BUT I'm worried the issue could still come on if I don't get a REAL fix to the issue.

Does anyone have any recommendations on how I could fix this? Thank you!

 

I've had my 2019 for about four months now and just got this issue for the first time today. I've put about 8k miles on the truck in those four months (now at just over 70k miles) and haven't had a single issue until today. Stock SR5 grill and no lift. Turning the truck off and back on seems to have cleared it up but it makes me worried now. Otherwise I love this thing. I do have an extended warranty so if it comes back again I'll probably have the dealer look at it.
