Hey Guys,

Bought a 2007 SCREW FX4 with 93km about a week ago and I love it !

The only thing i'm having a hard time with is the backup sensors. As soon as I turn on the truck the switch illuminates to OFF, when in reverse it stays at off even when pushing the button. Bottom line no matter what I do the switch says off.

Any ideas ?

 

one of the sensors are bad they just unclip from the bumper.. I think. But yeah. One of the sensors are bad

 

Is there a way I can figure out which one?

 

I think there are 4 sensors. Just buy a new one and swap them out until it's fixed. Process of elimination. Maybe not the only way, but probably the easiest.

 

turn your key to the run position.. e-brake on !!! put it in reverse.. go listen to each sensor.. the good ones will make a clicking sound.. the bad one will not.. replace as needed

 

I will get this chirp even if the switch on the dashboard says off ?

 

It's a clicking sound... and I believe so..
