My LX470 has the part time kit from Slee. The Center Diff Lock light does not indicate when the switch is pressed. The truck is definitely in 4wd but no center diff light. I wondered if other folks with the part time kit had this as well. Thanks.
Can’t speak to the part-time kit, but typically the position switch on the passenger side of transfer case is bad and needs to be replaced ($25) if your light isnt illuminated even though you hear the center diff engage.
