* Low fluid level: The 4WD system requires a specific type of fluid to operate properly. If the fluid level is low, the system may not be able to engage properly and the light will flash.
* Faulty sensor: There are several sensors that monitor the 4WD system, and if any of these sensors fail, the light will flash.
* Electrical problem: An electrical problem, such as a loose connection or a blown fuse, can also cause the light to flash.
* Mechanical problem: A mechanical problem, such as a worn-out gear or a damaged driveshaft, can also cause the light to flash.
If the 4WD torque on demand check light is flashing, it is important to have the vehicle inspected by a qualified mechanic as soon as possible to diagnose and repair the problem. Driving with a faulty 4WD system can be dangerous, as it can affect the vehicle's handling and stability.
