Great Wall Fengjun 5, 2WD want to change to 4WD?

Two-wheel drive conversion to four-wheel drive cannot pass the annual review. The driving form of the vehicle is written in the vehicle file, and the driving form of the car is changed after changing to four-wheel drive, so it cannot pass the annual review.

If it is a front-wheel drive to four-wheel drive, it is generally necessary to modify the rear axle, install a rear axle differential, and install a transmission shaft. This kind of modification has a high technical content, and the safety hazards are also great after the modification.

If the rear-wheel drive car is changed to four-wheel drive, then the gearbox needs to be replaced, the transfer case is added, the front axle differential is installed, and the drive shaft is installed.

No matter which drive form is modified to four-wheel drive, there are many parts that need to be changed, and the potential safety hazards in the later stage are also great.

It is recommended that car lovers do not change the driving form of the car casually, if you like four-wheel drive, then you should buy four-wheel drive car directly.

Some cars have low-end models that are two-wheel drive, but high-end models are four-wheel drive. Such a car can be directly modified with a four-wheel drive system on a high-end model, but it costs a lot of money, and it is better to buy a high-end model directly.

When the annual inspection is online, if the appearance of the car is changed, it will not pass the annual inspection. If the lighting system of the car is changed during the annual inspection, it will not be able to pass the annual inspection. After buying a car, don't modify your car casually.

Look at that kind of Wingle 5. If it's the Wingle 5 European version, this is simple, if it's the Wingle 5 national version (no wheel eyebrows, 215 * 75 15 small tires are) the kind of Wingle 5 don't change it, it's too strenuous.

Theoretically, it is possible to change to four-wheel drive, but there are too many things that need to be replaced, and the cost is high.

The Great Wall Fengjun 5 four-wheel drive failure can be changed to the gearbox, computer, sensors, transfer case, clutch friction plates, etc.

Computer Transmission Failure:

If the gearbox's computer fails, the program will not be able to analyze the data from the transfer case system's sensors. In order to ensure the normal driving of the vehicle, the computer of the gearbox turns on the protection mode, which will force the two-wheel drive to drive. At this time, you can reset the matching data of the transfer computer, and then rematch it for a test drive or try to upgrade the version of the transfer computer.

After the trial run, if the problem is still not resolved, it is recommended to replace the transmission computer.

Transmission sensor failure:

If the sensor fails, the transmission computer will protect the transfer case and force the two-wheel drive mode to start. At this time, you can use a special computer for the car to read the fault**, find out the fault sensor, and then replace it. During the warranty period, you can go to the 4S shop for free repair and replacement.

Multi-Zheng shed piece clutch limited slip differential fault:

Multi-plate clutch limited-slip differentials rely on clutch friction plates to output the drivetrain to the rear wheels. If something goes wrong, you can use a crane to lift the vehicle up and shout liquid, remove the transfer case, and remove the clutch friction plate. If the clutch friction plate is severely worn or burned out, the transfer case clutch friction plate needs to be replaced.

Summary. It is also possible that the electronically controlled four-wheel drive is controlled by the four-wheel drive system, and the electronic control system is composed of many sensors and actuators, mainly including the four-wheel drive transfer case and the front axle electronically controlled fork, under normal circumstances, the four-wheel drive ECU will not have problems, focus on checking the speed sensor, position encoder and related wiring harness on the front axle electronically controlled fork and transfer case, it is best to go to the local Great Wall service station to repair it, where the technician can accurately know the fault accessories by manual coding.

The Great Wall Wingle Five, the online four-wheel drive can't pull what's going on.

The Great Wall Wingle five is hung on the four-wheel drive, just like the brakes can't be pulled.

The two-wheel drive is okay.

Dear, isn't it hard to pull?

Yes, it just can't be pulled, and it takes a lot of effort to pull.

Can you hang up the 4WD?

You can hang up the four-wheel drive and save it.

It's just a lot of work, isn't it?

It's just hard to pull it, like a brake.

The reason may be the clutch wiring failure, some manual transmission cars still use wiring to adjust the clutch, the wiring sheath is very easy to break and affect the lack of clutch difficult to hang the gear, directly replace a wiring; The self-locking force of the gear on the clutch side is too large, which makes it difficult to get in and out of gear, so it is difficult to go to the repair shop to talk about the clutch cable and gear locking;

It is also possible that the electronically controlled four-wheel drive is controlled by the four-wheel drive system, and the electronic control system is composed of many sensing slag early devices and actuators, mainly including four-wheel drive transfer case and front axle electronically controlled fork, generally in the case of dispersion, four-wheel drive ECU will not have problems, focus on checking the speed sensor, position encoder and related wiring harness on the front axle electronic control dial or fork and transfer case, it is best to go to the local Great Wall service station to repair it, where the technician can accurately know the fault accessories through manual coding.

Did he change the front axle and the back axle cloth after passing the door? Differential.

It is possible that the front axle has been replaced, resulting in some abnormalities in the wiring harness or electronically controlled fork.

Summary. Hello, happy to answer your questions.

Hello, happy to answer your questions.

Hello, if you are in this case, you need to check whether there is a problem with the communication pin voltage of the four-wheel drive control module, under normal circumstances, the voltage of the pin of the can high can and the low communication of the macro is exactly equal to 5. If it is appropriate to unplug the plug to detect the voltage of the CAN communication pins, it is a problem with the Sijudou drive module itself.

What is the reason why the Wingle 5 does not have four-wheel drive.

First, check whether the communication pin voltage of the module is appropriate?

What does the communication pin voltage mean.

It is the CAN communication voltage, the voltage at which the module communicates with each other.
