What is the reason for the constant illumination of the 4WD light on the Great Wall Fengjun 5?
1 Answers
Great Wall Fengjun 5's 4WD light remains constantly illuminated due to mode switching failure or a malfunction in the intelligent 4WD system. The following are the differences between automatic 2WD and automatic 4WD: In terms of driving method: Two-wheel drive means only two wheels are the driving wheels, connected to the vehicle's power system; four-wheel drive refers to the vehicle maintaining a four-wheel drive form throughout the entire driving process. In terms of fuel consumption: The four-wheel drive mode can provide better off-road and handling performance at any time, but it cannot adjust torque distribution according to road conditions and has higher fuel consumption. In terms of the number of differentials: A two-wheel drive vehicle's differential allows the left and right (or front and rear) driving wheels to rotate at different speeds; in four-wheel drive, to drive all four wheels, they must be connected together. If the four wheels are mechanically connected, a center differential is required to adjust the speed difference between the front and rear wheels.
