How to reset the maintenance wrench on JMC Kairun?

[LolaDella]

While turning the key, press the brake pedal and accelerator pedal all the way down, then rotate the ignition key to the second position. Then press and hold the small trip reset button on the right side of the instrument panel for 2-3 seconds, while simultaneously pressing the accelerator pedal and brake pedal, and wait for about 15 seconds. After the maintenance light on the instrument panel starts flashing, release the accelerator pedal and brake pedal, turn off the ignition switch, and the maintenance light reset is complete.

I've been driving JMC trucks for over a decade, and resetting the maintenance reminder light must be done by the book. First, turn off the engine completely. Then locate the small button on the left side of the steering wheel and hold it down. Next, turn the key to the ACC position (where the dashboard powers on). You'll see a small wrench icon flashing in the center of the instrument cluster - keep holding the button for about 10 seconds until the icon completely disappears before releasing. This operation is like rebooting your truck - simple but requires following the sequence precisely. I always reset it myself after each maintenance to avoid queuing at service stations. The reminder light for oil and filter changes is very practical - don't ignore it, just follow the maintenance manual and you can't go wrong.

Last time I went for maintenance, the technician taught me a trick that works really well. First, don't start the car, press that small black button on the dashboard, located at the bottom right corner of the speedometer. With your other hand, turn the key to the power-on position, and the maintenance wrench icon will start flashing. Keep holding the button without releasing it, wait about seven or eight seconds, and it will turn off by itself, just like canceling an alarm clock. However, be aware that the button position might vary depending on the model year of the Kaivun, with older models having it on the lower left side of the steering wheel. It's important to clear the reminder promptly after maintenance; otherwise, it keeps lighting up, which can be annoying and distract you while driving. Doing it yourself takes just two minutes, saving both time and effort.

I always use this method to reset the wrench light after maintenance: turn off the engine → hold the dashboard button → turn the key to power on → keep pressing the button for ten seconds. It's similar to holding down the power button on a phone—it's a computer reset operation. Pay special attention to the button location. The JMC Kaixuan has three buttons on the left side of the steering wheel, and the middle one with a triangle symbol is the correct one. If the warning light doesn’t disappear, the timing module might be stuck—try disconnecting the battery for five minutes and repeat the process. If you can’t figure it out yourself, go to the service center. They’ll use a diagnostic tool to fix it in three seconds, but they charge 50 yuan.

As a Kaicheng owner, resetting the maintenance reminder requires some finesse. Last week I just did it: After turning off the engine, hold that small black button below the steering wheel, turn the key to illuminate the dashboard without starting the engine, and watch the wrench icon blink. Count to ten silently in your mind before releasing—the icon disappears instantly! It's much simpler than I imagined; I originally thought I'd need to remove the dashboard. Just be careful not to let cleaner spray from the AC vents drip onto the buttons—my neighbor's car had button malfunctions and needed a whole unit replacement. After clearing the maintenance reminder, driving feels so much smoother, reminding us that regular upkeep keeps the car running longer.

I've watched the mechanics operate it a few times at the repair shop, and it's actually super simple. There are four steps to reset the maintenance light on the Kaijing model: First, completely turn off the ignition switch; then, press and hold the reset button on the right side of the dashboard; next, turn the key to the ON position (second gear); keep holding the button until the indicator light goes off. The whole process is somewhat like a computer warm boot, resetting the maintenance memory of the onboard computer. The difference is that the newer Kaijing models can clear it directly from the dashboard menu by pressing the OK button on the steering wheel to enter settings and select reset. After the maintenance reminder is cleared, the next maintenance mileage will start counting down again. Performing this operation promptly can help avoid missing the maintenance cycle.
