How to Deal with Great Wall Fengjun 5 4WD Malfunction?

[Nettie]

Great Wall Fengjun 5 4WD malfunction can be addressed by replacing the transmission control unit, sensors, or transfer case clutch friction plates. Transmission Control Unit Malfunction: When the transmission control unit fails, it cannot analyze data from the transfer system sensors. To ensure normal vehicle operation, the transmission control unit activates a protection mode, forcing the vehicle into 2WD. In this case, you can reset and rematch the transmission control unit data, then test drive the vehicle or attempt to upgrade the transmission control unit version. If the issue persists after testing, it is recommended to replace the transmission control unit. Transmission Sensor Malfunction: If a sensor fails, the transmission control unit will protect the transfer case by forcing the vehicle into 2WD mode. At this point, you can use a specialized automotive diagnostic tool to read the fault codes, identify the faulty sensor, and replace it. If under warranty, you can visit a 4S store for free repair or replacement. Multi-Plate Clutch Limited-Slip Differential Malfunction: The multi-plate clutch limited-slip differential relies on clutch friction plates to transmit power to the rear wheels. If a malfunction occurs, you can use a lift to raise the vehicle, remove the transfer case, and inspect the clutch friction plates. If the clutch friction plates are severely worn, burnt, or deformed, they need to be replaced.

I used to drive a Great Wall Wingle 5 too. If the 4WD system malfunctions, don’t panic. Common issues include false sensor readings or a stuck transfer case. Try switching the drive mode a few times after starting the car to see if it resets. Check if any warning lights are on the dashboard; if so, turn off the engine, wait five minutes, and try again—sometimes minor issues resolve themselves. Also, ensure tire pressure and tread depth are consistent, as significant differences can trigger the system falsely. After off-road driving, clean mud from the undercarriage promptly to prevent component blockages. If problems persist, take it to a repair shop for computer diagnostics—avoid forcing it to avoid further damage. Regular transfer case oil changes can prevent these issues. Safety first, especially when off-roading—stop and inspect if a fault occurs.

Common causes of 4WD failure on the Great Wall Fengjun 5 include control module bugs or mechanical wear. First check for signs of oil leakage or listen for abnormal noises when starting. Use an OBD diagnostic tool to scan for trouble codes to identify whether it's an electronic issue or hardware failure; the former may be resolved by resetting the ECU, while the latter requires professional repair. Avoid frequently switching 4WD mode on slippery surfaces. Tire inspection is essential, as inconsistent pressure or significant wear differences may trigger false alarms. It's recommended to visit an authorized 4S dealership, as they are familiar with system calibration. When driving, avoid sudden acceleration to prevent overloading the transfer case. Record fault details for technician reference to facilitate quick repairs without affecting daily use. Address issues early to prevent minor problems from escalating.

My Fengjun 5 4WD also malfunctioned before, but a simple car restart fixed it! Check if the button is stuck and ensure even tire inflation. Avoid reckless testing in muddy areas to prevent vehicle damage. The system sometimes has minor glitches; updating the software can prevent recurring issues. If you encounter problems on the road, stop safely immediately—don’t risk driving. Keep the car clean to prevent sensor false alarms. If issues persist, visit a shop to reset the ECU or check for loose wiring. It’s quite hassle-free—most are soft faults that don’t affect long trips. Remind technicians to inspect 4WD components during routine maintenance. Safe driving is the top priority.
