Same issue.2019 Toyota Tundra. My battery was almost 5 years old so I changed it and the issue went away. Try a new battery before you tear your truck apart. Just sayin'.
Thank you for sharing,I’ll sent this video to the head mechanic at Toyota Dealership and let’s cross the fingers! They were also opening a ticket with the manufacturer and the lights went back on again!
MY FIX* Lights came on a couple days after i had tires put on. Turned out to be a front speed sensor wire had frayed. Techs must have broke tab off and it dangled. Of all things to cause all these lights. Fixed wire took for a short test drive and they cleared on their own. Hope this helps some of you narrow it down.
I'm having a similar issue with a 2018 Lexus IS300. It was in a front end collision but the radar itself was fine. Now the pre-collision light keeps coming on and off randomly as if there's a loose connection but I checked the harness, the connectors etc. No clue what's happening. Can you help?
Thanks for watching to simplify everything. Toyota have a list of options that you can pay to have added on your car at time of purchase. Trailer brake is one of them. On cars such as BMW when you don’t choose an option you basically can’t just add a controller and have the option at a cheaper cost. You will need to purchase the module and the controller and have it programmed if you wish to add a new feature to your car after purchase. On these tundras if you didn’t choose the trailer brake feature, all you have to do is purchase the controller and now you have it. The reason for that is because the car will still have the module and harness for the trailer brake assist. This can cause many issues because you can’t have a system on a car partially it’s either all there or not. So what i did is that i added the brake controller by doing that I added the missing component required to complete the circuit. This fixed it and the car has been driving for over a year without any issues. This might not fix your car because every car is different, you might’ve hit a deer or a bird and now you have an issue with your adaptive cruise could be many reasons. This is free information.
Shouldn’t Toyota fix this if it’s a problem I just bought a brand new 2023 Toyota Tacoma I’ve had it since December and now I’m having this issue. In addition my windows won’t go down and my heater/ac it stuck on. Thankfully it’s stuck on A/C or I would be melting in my truck because I can’t put the windows down.
I just experienced this code last night. I have the trailer brake system installed on my 2019 Tundra. I'm going to try and disconnect the battery to fix it.
Were there others issues and not just the alarm? My 2023 Tacoma has this alarm plus lane departure alarm and the windows stopped working, the heater/ac can’t be changed, I can’t use auto lights, and headlights will turn off on their own. Originally the dealership changed a fuse and it worked fine for a few months. Slid on the dirt road last week and now replacing the fuse won’t fix the issue. Keeps blowing.
Hi I have a 2018 Toyota RAV4 that was hit when parked and lifted on to sidewalk and knocked over a parking sign the mechanical damage was 2 front struts and the spindle. The collision shop replaced the two headlights, front bumper left and right fenders and back bumper. It drives perfectly but 1 week later the lane departure and Precollision warnings came up on dashboard what do you suggest I do to get it fixed? I checked and sensor cables are connected. It drives perfectly fine haven't taken a highway yet until i get it fixed. Could you please advise me i have to get emmissions inspection before end of June and I don't think I'll pass. Should i go to Toyota or look for a specific mechanic that can help me because out of all the information online you were determined to find the right solution. I live in NY. Thank you.
I have a 2018 tundra sr5 with the trailer brake instaled from factory and have the same issue, I went to the dealership and wanted 900$ to fix it and didn’t said what was the problem…. I want to understand what is causing this. But no clue
