What this sensor looking thing under my truck

I have the sensor that came off the frame of my truck on the undercarriage on the side of the driver. I don’t know what purpose it serves or what it’s for. I reconnected it, but I need to find the original way to hold it in place. Does anyone know whats its for and how it could of come loose?

 

Fuel Pump Control ECU

 

Seat ejector

 

They are watching…

 

Thanks everyone

 

Holy crap! Looks like someone forgot to install the nuts! Are you the original owner? Did you have any work done where they were working on it? Inquiring minds want to know.

 

yeah just take it out you don't need that

 

I think that’s the module that delays transmission shifts and reduces driver headroom.

Or it could be fuel pump control.

To be sure, try removing & driving for a while, report back your findings.

 

If this is a used truck, someone may have temporarily removed the unit to uninstall some rock sliders. They probably didn't reinstall it properly.

 

Here is how it was originally installed and why someone may have messed with it.

 

This truck is part of a rebuild from salvage title to clean title.

 

If you start to hear a beeping sound that begins to increase it's pace...RUN!!!!

 

Exactly its an explosive device that can be armed for the truck to self destruct.

 

^Yep, by sending a thermal runaway command to the fuel pump. On 2020+ this can be triggered remotely through the Toyota app.

 

Curious what State allows that process?

I mean you can certainly repair a salvage title vehicle and put it back on the road. But I've never seen the word 'salvage' leave the title to become 'clean'.

 

Correction i meant rebuild.

 

Un plug it and see if it throws a code.
