What is the reason why the Land Cruiser differential lock cannot be turned off?

It may be that the method is not used correctly. The method to turn off the Land Cruiser differential lock is: there is a central differential lock button behind the gear lever, press it once to turn it off. More introductions about the Land Cruiser are as follows: 1. Power: The Land Cruiser uses two engines in total, one is a 4.0-liter V6 naturally aspirated engine, and the other is a 4.6-liter naturally aspirated V8 engine. 2. Technology: The Land Cruiser includes ABS anti-lock braking system, EBD electronic brake force distribution system, VSC vehicle stability control system, etc., ensuring safety performance when driving at high speeds or on slippery roads. At the same time, passive safety equipment such as 6 SRS airbags can provide all-round protection for the safety of drivers and passengers.
After driving for so many years, especially during off-roading, my Land Cruiser's differential lock has had several instances where it couldn't disengage, mostly due to mechanical parts getting stuck or worn out. For example, if the differential lock gears are filled with mud or debris and not cleaned promptly after off-roading, they can easily get stuck. It could also be due to aging drive shafts or bearings, or oil seal leaks causing parts to rust—once rusted, the gears can be very difficult to move back into place. Electrical issues are also common, such as poor contact in the control module or sensors, unstable battery voltage, or a faulty relay, all of which can disrupt signal transmission. My advice is to do a simple cleanup after every off-road trip, regularly apply some lubricating grease to the differential lock, and not wait until problems arise. Safety comes first—a stuck differential lock on the highway could lead to a loss of control.
