The reason why the Land Cruiser differential lock light keeps flashing is that the differential lock is either not engaged or not disengaged. If this situation occurs, it is recommended to go to a 4S shop and have professionals use specialized diagnostic equipment to check the fault code before proceeding with repairs. 1. Power: The Land Cruiser is equipped with two engines, 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 6SRS airbags provides comprehensive protection for the safety of drivers and passengers.
I've been driving a Land Cruiser for over ten years, and recently encountered the issue where the differential lock light kept flashing and couldn't be turned off, which was quite annoying. It happened during off-roading, with the light continuously flashing indicating a problem with the differential lock system. My first thought was that the sensor might have failed, perhaps due to mud or water dirtying the connector, causing unstable signals. It could also be due to aged wiring causing a short circuit or the differential lock control unit burning out. My advice is not to drive hastily; first, check the fuses and connectors—a simple cleaning often solves the problem. If that doesn't work, you'll need to test the electrical system. Leaving this issue unfixed can affect the 4WD performance and make driving unsafe on slippery roads. In the end, I had to go to a repair shop to replace the sensor. Regular maintenance should include cleaning the undercarriage to prevent dust buildup.
