Front Park Sensors

What’s up guys-traded a 4Runner for a 14 Platinum.

I’m getting a parking sensor error that I believe I’ve narrowed down to the front 2.

I can hear the back 4 click, but neither of the front 2. The error message also shows the front 2. Tried swapping them with new-that didn’t work.

Is there an associated fuse or relay? I’m not seeing anything for park sensors on either fuse box diagram.

This happened after pulling the trim below the steering wheel to put in a brake controller, but I’m not sure if that’s associated or because I just happened to test the button after.

 

Welcome to the forum.

Search for 'parking assist' to find info on the sensors.
You can find wiring diagrams here for the complete circuit, and everything else on your truck.

If the rears are working, I don't see it being a fuse or relay.
The front doesn't have a separate power circuit.

Seems the front sensors have their own input to the sonar ECU.
There are some connectors, as well as the plug into the ECU, you could check.
