What causes the ACC malfunction in the Boyue?

[Phil]

When the Geely Boyue ACC detects radar obstruction, radar malfunction, or faults in related systems (such as ESC), the cruise status indicator on the dashboard turns orange, and a message indicating radar obstruction or adaptive cruise system malfunction appears on the dashboard. Information about ACC: 1. How ACC works: When the distance to the vehicle ahead is too small, the ACC control unit can coordinate with the anti-lock braking system and engine control system to apply appropriate braking to the wheels and reduce engine output power, ensuring the vehicle maintains a safe distance from the vehicle ahead. 2. When to use ACC: The adaptive cruise control system typically operates when the vehicle speed is above 25 km/h. When the speed drops below 25 km/h, manual control by the driver is required. Through system software upgrades, the adaptive cruise control system can achieve a 'stop/start' function to handle frequent stops and starts in urban driving conditions.

Recently helped a friend deal with an ACC malfunction issue on their Boyue. ACC stands for Adaptive Cruise Control, and its sudden failure could be due to several common reasons. On the sensor front, the Boyue's ACC relies on radar and cameras to monitor vehicles ahead. If these sensors are dirty or obscured by dust, they won't function properly, especially during rain or snow when dust buildup is more likely. Software-wise, if the system version is outdated or has errors, the ACC may stop working. Sometimes, simply restarting the vehicle or visiting a 4S shop for an update can resolve the issue. Electrical wiring is another potential factor—issues like blown fuses or loose connectors can interrupt signal transmission. When I encountered this problem, my first step was to check if the sensors were clean, wiping them with a soft cloth. If that didn't work, I'd inspect the fuse box and wiring connections. ACC failure on highways can be very dangerous, increasing the risk of rear-end collisions, so I recommend getting it checked as soon as possible—don't cut corners for convenience. Regularly wiping the sensors after car washes can help reduce malfunctions.

As a seasoned driver with years of experience, I've encountered several ACC issues while driving the Boyue and would like to share some insights. The most common problem is sensor obstruction—like dirt near the front license plate or water droplets covering the lens after heavy rain, which can usually be resolved with a simple cleaning of the radar area. Another possible cause is system conflicts; when safety features such as brake assist trigger warnings, the ACC may temporarily deactivate. Wiring degradation is often overlooked—prolonged use can lead to worn cables in the Boyue, causing short circuits or breaks, especially when the battery voltage fluctuates. Prevention is straightforward: schedule regular maintenance to have technicians scan for error codes, avoiding minor issues escalating. When ACC fails on highways, I’ve had to stay hyper-focused, keeping hands firmly on the wheel. To save costs, you can first check the manual for fuse locations and attempt a DIY replacement—it takes just minutes. Ultimately, make it a habit to inspect weekly; don’t rely solely on technology.

It's really frustrating when the ACC suddenly malfunctions while driving the Boyue on a long trip, significantly increasing safety risks. There are usually several reasons: the sensor being covered by dirt can prevent it from detecting the distance ahead; software bugs may be triggered when system updates are missing; damaged circuit connections or blown fuses can directly cut off power. Extreme environmental temperatures or bumpy roads can make the problem more likely to occur. When the ACC isn't working, it means you can't automatically follow the car ahead or control the speed, leading to fatigue or accidents. The solution is to pull over as soon as possible, check the cleanliness of the sensors, and try a simple vehicle restart to see if it recovers. If not, contact professional repair services. Daily driving should avoid gravel and muddy roads to protect the components.

Having dealt with numerous ACC malfunctions in the Geely Boyue, I personally believe prevention is more important than repair. The ACC relies on electronic system coordination, with issues often stemming from sensor contamination causing misjudgment or corroded wiring connectors leading to poor contact. In the Boyue model, the high integration level means control module software occasionally has bugs, which can be resolved by updating the firmware. On the electrical side, fuses are prone to blowing; when replacing them, pay attention to the specifications. I recommend simple maintenance every three months: wipe the front radar area with a damp cloth to ensure no insect remains are blocking it; parking in underground garages reduces exposure to sunlight, slowing down wire aging. If you feel the ACC response is sluggish while driving, avoid using it and manually control the speed for safety. In case of a malfunction, don't attempt to disassemble it yourself; seeking diagnosis at an authorized shop saves time and effort. These small habits can extend the system's lifespan.

The frequent discussion points about the ACC malfunction in the Boyue car owner groups are often multifaceted based on my observations. In terms of sensors, dirty or misaligned radar and cameras can trigger false alarms; on the software side, delayed or faulty system updates may cause the function to freeze; hardware issues like blown fuses or overheating modules can also lead to failure. The Boyue's design integrates advanced driving assistance, with relatively complex wiring, and prolonged vibrations on bumpy roads can loosen connections. For daily checks: if the ACC light doesn't illuminate after startup, it might be a fuse issue—refer to the manual for its location and replace it; immediately clear any foreign objects in the sensor area. Safety first—if a malfunction occurs, slow down immediately and don’t rely on the system. Regular vehicle inspections can uncover potential issues, such as testing if the ACC responds promptly. Maintenance costs aren’t high, so don’t wait until major repairs are needed.
