Crown's three warning lights illuminate simultaneously. When this situation occurs, car owners cannot resolve it themselves. It is recommended to visit a 4S dealership to have professional technicians read the fault codes. The fault codes can help technicians quickly identify the cause and location of the malfunction.

I've been driving a 12th-generation Crown for several years. Last year, I encountered a situation where three warning lights came on simultaneously and almost thought the car was done for. The ABS light, brake light, and engine light were all illuminated. Following online advice, I checked the ABS sensors on the wheels and found that the right front wheel sensor was clogged with mud. After cleaning it and reconnecting, the lights went off during a test drive. Another time, cleaning didn't work, and I realized the system computer needed a reset. I borrowed an OBD tool, connected it to my phone, and got it sorted. It's a good idea to regularly clean the sensor areas during maintenance to prevent dirt buildup. While this car is a classic, it does have its share of minor electronic issues. Addressing them promptly can prevent bigger problems. DIY fixes can save some money, but if you don't have the tools, it's best to take it to a shop.

As a car enthusiast, I enjoy DIY car repairs and have researched the issue of the three warning lights in the 12th-generation Crown. It's usually caused by false alarms in the ABS system. The steps are simple: first, park and turn off the engine in a safe place; then check each wheel sensor for looseness or dirt, clean them thoroughly and plug them back in securely; if the lights remain on, try restarting the vehicle to see if they disappear. Without tools, this is sufficient; if the problem persists, use an OBD scanner to read the fault codes to determine if a sensor is faulty or if the wiring is aged and needs replacement. I once replaced a front wheel sensor for just a few dozen yuan to fix the issue. Remember to dry these areas when washing the car to prevent problems.

Crown car's three warning lights often illuminate together; don't panic when ABS light comes on. Quick solution: First clean the wheel sensor positions with a dry cloth, wipe off dirt and reconnect tightly. If lights go off, problem solved. Otherwise, use OBD tool to read error codes – may require sensor replacement or ECU reset. Safety first, don't force driving; professional inspection is faster and better. Regular maintenance prevents such minor faults from causing delays.
