Problem overview

Some Lexus LX570 owners report experiencing a blinking differential lock light upon engine start, which may indicate a potential issue with the differential locking system despite the absence of diagnostic codes. This problem can stem from mechanical failures within the locking system, possibly due to sensor issues or a stuck center differential lock from lack of use. Additionally, some owners find that electrical problems, such as faulty connections or wiring issues, can cause the light to blink. To troubleshoot, it is recommended to try resetting the system by turning off the engine and restarting it; however, if the issue persists, seeking a professional inspection from a qualified mechanic or dealership is advisable. Prompt attention to this matter is crucial for ensuring the proper functioning of the differential locking system and maintaining optimal performance and safety while driving.
