Help! What is this switch?

[pault]

That's an aftermarket switch. They are commonly used for beacons, work lights and such, turn it on and have a walk around the outside.

 

If nothing has come on pop the blanking plug out and have a look see if there is anything attached to the fed side of the switch.

 

Its entirely likely it ran a beacon or similar that has been removed

 

Thanks man that makes a lot of sense. It was very confusing as i can see the VSC light in the display which wasnt coming on. Strange though as there is no evidence of a beacon ever being fitted. Plus the dealer never said anything about it. Dont suppose he had any reason to tell me anyway.

I had the same switch on my hilux, it was for turning off the rear parking sensors if you had a trailer on so they did not constantly go off when backing up with a trailer on, if yours is an HL3 it wont have vehicle stability control at all.

i have one its your immobilizer light to say its working. when you lock the truck it will light up and flash.should have looked more as you say its a switch still say its to do with the locking system. switch it on to lock doors switch it off to unlock doors. so the kids can not open doors. in place of the little barrel on doors which you turned to stop doors being opened from inside
