How to Deal with Honda ACC System Malfunction?
2 Answers
If the engine malfunctions, regular maintenance is required. Different grades of lubricating oil will undergo changes in quality during use, so it is necessary to regularly change the car's lubricating oil. The engine's intake system mainly consists of two parts: the air filter element and the intake duct. Depending on usage conditions, the air filter element should be cleaned regularly.
I once experienced a Honda ACC system failure while driving myself. That time on the highway, the cruise control suddenly malfunctioned, which was really nerve-wracking. My approach was to immediately switch to manual driving to ensure safety and pull over. Then, I restarted the engine to see if it would recover, but the issue persisted. Next, I checked the dashboard for any warning lights, opened the manual on my phone, and found that the ACC relies on the front radar sensor, which might be blocked by dirt. I gently cleaned it with a damp cloth. If this didn’t work, I would drive directly to the nearest 4S shop or Honda service center and let the technician read the fault codes with a computer. Remember, don’t force driving with a faulty ACC—it’s too dangerous if the brakes fail. Usually, I avoid using this system in rain or snow and wash the car more often to keep the sensors clean.
