Toyota 4LO fault light flashing refers to the low-speed four-wheel drive. When the 4LO indicator light on the vehicle dashboard flashes, it indicates a fault in the low-speed four-wheel drive system, requiring repair. If it is a vehicle speed sensor failure, you should promptly go to the car's 4S store or repair shop to inspect and repair the car's sensor. If the issue persists, it is recommended to conduct a comprehensive inspection of the car engine. Below are the solutions for when the Toyota 4LO fault light flashes: 1. Switch between high-speed four-wheel drive and low-speed four-wheel drive several times, and press the accelerator a few times during the switching process; 2. Disconnect the negative terminal of the battery for 5-10 minutes and try to use the vehicle's built-in repair system for repair; 3. Check the ABS sensor plugs on the front and rear wheels and firmly press the transfer case plug of the four-wheel drive; 4. Check whether the exhaust system and the three-way catalytic converter are blocked; 5. Perform a reset of the fault unit by short-circuiting the 4th and 12th terminals of the vehicle's OBD interface for 10 seconds, and clear the fault code at the same time; 6. Go to a repair shop or 4S store to use a decoder to read the specific fault code, and then inspect and repair according to the fault code read.
