LX470 LC100 Center Diff Lock Indicator

[@guniseran]

What's the sensor called? My diff lock does not engage at all? Is this what I need ? Thanks

So there is no other errors than not engaging? How would you know it’s the switch and not any other thing?

...or did’nt the lamp not lighten up?

The differential would engage, but the indicating dash lights did not illuminate. You would not know if the differential was engaged unless you pay attention to the behavior of the vehicle. That's why it was important for me to replace the switch. (Someone might drive around with the gear locked up unknowingly). If the gears are lined up and the vehicle parked you can hear the diff locking after pushing the button. This is the case in this video.
