Front radar sensors not working

[Suggs.OR]

Hey friends.

I just got my Supra wrapped this last week. I got several error messages the day after saying the front radar sensors were not working. Radar cruise, front collision, and pedestrian sensors were not working. Shut the car off and came right back when car turned on. I had a low battery warning when looking at the ECUtek app but cleared the code and it didn’t come back.

Has this happened to anyone? Is it the wrap on the front sensors that may be impacting this? I don’t know why it wouldn’t impact back sensors though.

I bet they took the front bumper off and forgot to reconnect sensors. Or they disconnected and reconnected these sensors with the battery connected.

I had a bad sensor on my 2020 that caused all sensors to report a fail when the car was put into reverse. Took it to the local Toyota dealer assuming it would be covered under warranty. They managed to find a very small ding in one of the front sensors, likely caused by a rock. $700

Yours sounds to be wrap related ... but I'd still take a close look at all sensors for small nicks.

Yes! @Thraxbert nailed it. When I had all the stuff done to my car recently, they disconnected and reconnected the sensors with the battery connected. Threw these exact same errors. I tried clearing them with Bimmercode, but they came back when I restarted the car. Had to take it to the dealership to have the codes cleared for good.

I’m waiting to hear back from them on if they took the bumper off. I guess everyone doesn’t respond to messages as early as I’m awake .

im guessing they never disconnected the battery because of the low battery warning I got in the app.

thanks everyone. I’m going to try and disconnect the battery and see if that clears it. If not it’s a trip to the stealership to get them to clear them.

I've disconnected the fronts with battery on twice actually. Never had any problems.. both parking sensors and radar.
Maybe they didn't connect 2 harnesses properly, or moved or didn't connect the radar, as your title says radar.
Or they've damaged the sensors or they're maybe still covered??

I want to be clear on this. Are your sensors covered by the wrap????

Can someone show where these sensors are at? I have the same issue after I got my laser jammers installed

The parking sensors? The little round things around the bumpers.

I'm with you on that. Had my bumper off twice with the battery still connected and never had anything odd happen.

I’ll get this bumper off soon and see if it’s easy

Super easy

Ah, gotta love that piece of shit sensor. I fucked mine up earlier this year.

Also, it's not the small parking sensors on the bumper. It's the sensor behind the black panel on the passenger side grille.

Damn I want your Toyota dealer!

Yea there is wrap on the sensors.

That is your problem. Of course they are going to give errors if they are covered up.
