Good morning to yall, ive got sum issues with my 05 king ranch's rss system. Ive watch sum videos and from those i can tell the all my sensor are working by the clicking noise they make. So im wondering wat to check next? Id sensors are good then wat else can it be?

 

what's it doing or not doing ? have you checked for DTC's fuse's all good ?

 

If you have a meter, check the dash disable switch. It could be bad, but admittedly, it's a long shot..

 

It does nothing each sensor only makes this clicking noise. They appear to function with the on/off button, im wondering if theres anything else i can check before having a comp. hooked up. The button has been light since i had the truck which is a 05 king ranch 4x4 its has a 177,000.

 

what does the button say on or off ?

 

Mine only lights up when I turn it off. If your light is on all the time, this could be the indication something is wrong/failed.

 

The button stays lit but im pretty sure it might be working. If u press it once the sensors will click and then pressed once more the sensors will stop clicking. But the button stays lit up

 

While the switch may be cycling the system on and off, the constant light may mean something.
