How to Solve the Flashing 4LO Light on the Land Cruiser Prado?

Press the brake pedal and shift into N gear, then lift the first of the four levers in front of the center console from left to right. After three seconds, these lights will no longer appear. Precautions for using the Toyota Land Cruiser Prado are as follows: 1. The diesel engine is highly durable, with relatively lower RPMs, resulting in reduced wear on engine components. However, diesel engines require specialized engine oil, which should be changed every 6,000 kilometers. Additionally, regular maintenance of the air filter, oil filter, and diesel filter is essential. 2. Diesel engines offer excellent power and higher combustion efficiency, making them more fuel-efficient. A diesel engine of the same displacement delivers stronger power and lower fuel consumption compared to a gasoline engine. However, never run a diesel engine until it is completely out of fuel. Running on empty can cause the engine to draw in air, leading to severe damage. 3. When starting a diesel vehicle, avoid pressing the accelerator pedal. Also, avoid rapid acceleration or high RPMs during initial operation. After prolonged high-speed operation, do not shut off the engine immediately. Instead, let it idle for two to three minutes to cool down before turning it off to prevent heat buildup.
As a long-time Land Cruiser owner with over a decade of driving experience, I've encountered the 4LO flashing issue several times. It usually occurs when the 4WD system detects abnormalities like road slippage or sensor malfunctions. For troubleshooting, first park the vehicle on level ground, turn off the engine and wait five minutes before restarting. If the light keeps flashing, try manually switching 4WD modes—shift to N gear and press the mode button several times. If the problem persists, it might indicate circuit shorts or control unit failure, requiring professional inspection. I've attempted DIY fixes with limited success—ultimately needed dealership computer diagnostics for resolution. Don't ignore the flashing warning; prolonged neglect may damage the transfer case, especially during off-roading when forced operation should be avoided (safety first). Regular maintenance with wiring harness cleaning and avoiding muddy terrain can prevent issues proactively.
