Hey Scotty, I bought a used 2014 Toyota Tundra crewmax 4x4 about 6 months ago. It's got about 110k miles on it now.
Recently it stopped going into 4Lo. It goes into 4hi no problem but when I try to go in to 4lo the light just keeps blinking. I can hear the transfer case click but the light just continues to blink and if I put it in Drive or reverse the car beeps letting me know it's not in 4lo.
I recently took it offroading for the first time. Before the trip I tested the 4lo and it engaged. On the trip i put it in 4lo for a small steep incline and it worked. Ever since then it will not engage now.
Have you encountered this before and what can I do to fix it?
are you stopping and putting it neutral? if you are just give it a little gas and then it should engage.
that how I get mine to engage easier.
Have you been changing the transfer case and differential fluid? If not, I would change it out with some really good synthetic, like amsoil to get things cleaned up. If you haven't been using the 4wd on a regular basis, at least some, try to do that to help prevent issues in the future.
I do very little work on four-wheel drive vehicles you want to pray it's something to do with the actuator that goes from low to high go to a good four-wheel drive specialist who is equipment to test it maybe it's just an actuator
