Great Wall Fengjun 7 Diesel Version maintenance light reset method is as follows: 1. Turn off the ignition switch, shut down the engine, and press the right button on the instrument panel with your left hand. 2. Keep holding the right button with your left hand, then turn on the ignition switch while continuing to hold the right button until the maintenance light enters the reset mode, then release the right button. 3. Within 20 seconds of releasing the right button, press the left menu button once to confirm the reset. Additional information: Fengjun, also known as Fengjun Pickup, is a model launched by Great Wall Motor Company Limited. Its design is in line with international standards, featuring a bold and imposing appearance, exquisite craftsmanship, full lines, and a unique style, making it a fashion pioneer leading the development of pickup trucks. The comfortable and rich configurations further enhance the driving and riding experience, setting an absolute benchmark in the pickup truck industry.

Last time after a minor service for my Fengjun 7 diesel version, I also encountered the maintenance light coming on. Actually, manually resetting it is quite simple. Sit in the driver's seat without pressing the brake, long-press the odometer button at the lower right corner of the instrument panel while turning the key to the power-on position (no need to start the engine). At this point, the instrument panel will start flashing a countdown. Keep holding the button without releasing until the countdown ends, jumping from 9.9 to 0.0, then immediately release the button and turn off the power. Wait for 30 seconds and turn the power back on, and the little yellow wrench symbol will disappear. A reminder: older instrument panels require this method, whereas newer ones with LCD screens need to be operated through submenus. Also, before resetting, it's best to confirm that the oil and oil filter have been changed, so as not to let the warning light obscure the actual maintenance needs.

I've serviced dozens of diesel-powered Great Wall Wingle 7 trucks for maintenance light reset issues, and the key lies in timing the power disconnection correctly. First, close all doors, hold down the TRIP button on the left side of the steering wheel with your left hand, then power on the vehicle with your right hand without starting the engine. Watch for a flashing English menu to appear in the odometer position, continue holding the TRIP button for about 10 seconds until the reset menu displays. Quickly tap the button to select RESET, then press and hold to confirm for 3 seconds - the maintenance light will turn off. The entire process must be completed within 20 seconds, otherwise you'll need to restart. Special reminder for vehicles with aftermarket instrument clusters: operation logic may differ, if unsuccessful, use a diagnostic tool for reset instead of random button presses that might trigger airbag warning lights.

A tested and effective lazy method: There is a menu toggle button on the head of the wiper stalk on the right side of the steering wheel. Press it five times while parked to switch to a sub-menu. When you see the wrench icon, press and hold the confirmation button on the top of the wiper stalk for five seconds until the dashboard numbers start blinking. Then use the up and down buttons on the wiper stalk to adjust the value to zero, and press the confirmation button to save. Some model years require performing this operation twice consecutively to clear the reminder. After completing the process, remember to perform two cold starts for self-check. This method is more convenient than fiddling with buttons, but be careful not to touch the wiper switch during operation—last time I accidentally triggered the washer pump and wasted half a reservoir of washer fluid. The maintenance reminder on diesel models is more stubborn than gasoline versions; if it fails, just repeat the operation three times and it will work.

Off-road enthusiasts all know there's a trick to resetting the maintenance light on the Great Wall Wingle 7. For push-button start models (with one-key start), first press the start button twice without stepping on the brake to power on, then quickly turn the knob at the top of the left steering column light stalk back and forth three times. When the engineering menu pops up on the instrument cluster, simply select the oil life reset option. The method for mechanical key models is more brute-force: open the hood, disconnect the negative battery terminal for 30 seconds, then reconnect it - this hard reset works about 90% of the time. However, after battery disconnection you'll need to reset the window anti-pinch function, so it's recommended to use the official reset method first. Be cautious with the battery disconnect method if your vehicle's ECU has been modified - my racing edition lost all turbo pressure data after the last reset when I had custom tuning installed.

Here are some common DIY methods used in repair shops: After turning off the engine, press and hold the two small buttons below the dashboard (the ones used to check fuel consumption and mileage). While keeping them pressed, turn the key to the ON position for 15 seconds until all indicator lights turn off and then light up again before releasing. However, this method doesn’t work on new ECUs manufactured after 2019. Special note for diesel versions: After resetting the maintenance light, it’s best to drive about 20 km to let the after-treatment system complete its self-check. I’ve seen cases where people went on long trips immediately after resetting, causing DPF regeneration issues. If you’re unsure how to do it, don’t worry—when buying Great Wall-specific engine oil at gas stations, ask the sales staff for help, as most stores have reset tools. However, new regulations now require maintenance records to be uploaded to the cloud, and professional maintenance at 4S shops will automatically clear fault codes.
