How do i know if my Tacoma has factory RR diff lock

Hey guys a few months back i bought a 2010 Tacoma which had the RR diff lock button but when i pressed that instead of locking the diff it turned off the rsca
U think there's something wrong with the wiring ?
And if i go under the truck and inspect the diff is there anything that indicates if I have the diff locks ??

 

Look at your rear axle where the drive shaft meets the pumpkin. You will have a small (Coke can sized) electric motor to the right of that.

 

There will be a elocker unit on the drivers side front of the diff

 

Sounds like somebody messed with wiring. When you press the rr diff lock button, a red indicator should flash on the dash.

 

What happens when you press your rsca button? Thats what i want to know.

 

Thank you guys I'll check it out asap
And the thing is i don't have an rsca button that's why i was so confused

 

pics??

 

This is what I've got when i press the RR diff lock button the Rsca off light comes on
And i checked my diff i don't have the electric motor on it so no diff lock
I don't know who the hell put that button in

 

You dont have a trd offroad. I hope you didn't get ripped off.

 

thats where the rsca button is on my 2015 taquito.

someone put that switch in there to get rsca..and put the rong switch in there

 

I don't think you have a rear e locker (I think), because my rear locker is located in the upper middle blank

 

No you dont, looks like he was short a switch so he jerryrigged it with a RR one he had laying around most likely

 

Nah man the price was okay
But I'm disappointed that it's not a Trd offroad though but none the less I'm still driving circles around other 4x4's when we go

 

And yeah looks like it
