What is the solution for the ACC and PCS malfunctions in the Boyue?

[LeKarter]

The ACC and PCS malfunctions in the Boyue require visiting a service center to diagnose the cause with specialized computer equipment and clear the fault codes. Here are the relevant details: 1. ACC (Adaptive Cruise Control System) The Adaptive Cruise Control System is an intelligent automatic control system developed from existing cruise control technology. During vehicle operation, a distance sensor (radar) installed at the front continuously scans the road ahead, while wheel speed sensors collect vehicle speed signals. When the distance to the vehicle ahead becomes too small, the ACC control unit coordinates with the anti-lock braking system and engine control system to apply appropriate wheel braking and reduce engine power output, maintaining a safe distance from the preceding vehicle. 2. PCS (Pre-Collision Safety System) The Pre-Collision Safety System automatically detects obstacles ahead and calculates collision probability. If the system determines a high collision risk, it triggers an audible alarm. The system can also automatically adjust safety systems including pre-collision brake assist, emergency steering assist, and vehicle dynamics integrated management to avoid collisions when possible. When a collision is deemed unavoidable, the system pre-tensions front seatbelts and initiates braking to minimize damage.

When my car experiences Boyue ACC and PCS malfunctions, I first try a simple system reboot: turn off the engine, wait a few minutes, and restart to see if the ACC button can be reactivated. If that doesn't work, I manually clean the front radar sensor area, as it might be covered by dirt or insects affecting signal transmission, using a soft cloth for gentle wiping. If cleaning proves ineffective, I recommend using an OBD diagnostic tool to check for error codes. Common issues include radar module damage or software conflicts, in which case visiting a 4S shop for firmware updates or part replacements is the most reliable solution. The ACC system uses radar to detect vehicle distance for adaptive cruise control, while PCS prevents rear-end collisions; malfunctions in either significantly reduce driving safety. Therefore, regular maintenance, such as monthly sensor cleaning, is crucial. Ignoring these issues may lead to failure of assistance functions, greatly increasing risks during high-speed driving. After each repair, I pay special attention to system stability before hitting the road again.

My experience in troubleshooting the ACC and PCS issues on my Boyue is: when the warning light comes on, I try restarting the engine or resetting the system through the settings menu, as minor electronic glitches can often be resolved this way. If that doesn’t work, I take it to the 4S shop for professional diagnostics. Last time, my car’s radar sensor was dirty, causing false alarms—cleaning it fixed everything. The technician also emphasized that software updates are key to prevention, so now I request checks on related modules during every maintenance visit. When parking, I avoid areas where dirt accumulates, and during car washes, I focus on cleaning the sensor areas. ACC failure makes highway following unsafe, and PCS deactivation increases the risk of rear-end collisions, so I address issues promptly to avoid accidents in emergencies. I even recommend regular maintenance of these features to friends when they buy cars.

ACC and PCS malfunctions must never be ignored. I immediately parked the car in a safe location, checked the reset procedures in the manual, or cleaned the radar sensor area. If that didn't work, I contacted towing services for repairs, as ACC adaptive cruise relies on forward scanning, and PCS serves as the first line of defense against collisions. When these systems fail, the risk of assisted braking failure is extremely high. I emphasize that any action should not be delayed. Develop a habit of maintaining the sensors regularly to avoid dirt accumulation. System software updates can reduce false alarms, and it's recommended to have professional inspections every six months to ensure safe driving.
