How to fix the Envision four-wheel drive shutdown fault

According to my report, many friends do not know much about some car problems in cars. Friends often ask me: What is the problem with the four-wheel drive stalling of the Envision (check transaction price | model details)? Let me briefly introduce myself. Regarding this issue, you can refer to it, maybe you can avoid some detours. It is not a malfunction that the Angwei four-wheel drive turns off. Conway's four-wheel drive system is a timely four-wheel drive system, and the four-wheel drive is turned off, which means that the four-wheel drive mode is not required at this time.

Conway’s four-wheel drive does not require the driver to manually cut it off, the car will automatically switch according to road conditions.

For example, when driving on paved roads, the car will not activate the four-wheel drive system, and usually uses two-wheel drive.

The four-wheel drive mode will only be activated when the road surface is uneven, rainy or snowy, or the driving wheels are slipping. The trip computer can automatically check and then distribute the engine output torque to the other two wheels, switching to four-wheel drive.

A simple understanding is: timely four-wheel drive will only have a four-wheel drive system when it is moderate, and in most cases it will still be two-wheel drive. The computer will automatically switch to two-wheel drive or four-wheel drive mode according to the car's driving conditions, without manual operation.

The current mainstream four-wheel drive systems mainly include three categories: full-time four-wheel drive, part-time four-wheel drive and timely four-wheel drive.

As for the differences between the three four-wheel drive systems, I will not patiently introduce them here. Interested friends can check the information online by themselves.

Conway is a mid-size SUV produced by Buick. The official guide price is 214,900 to 309,900 yuan.
