What to Do with Dashboard Display Error Codes?
3 Answers
If this situation occurs, it is recommended that the car owner go to a 4S shop to read the fault codes. Only in this way can the fault location and cause be quickly identified. Some faults cannot be repaired by the car owner themselves, and some faults require professional personnel from the 4S shop to fix. There are many electronic systems in the car, and the circuits are very complex, making it impossible for the car owner to repair them on their own. If some equipment or systems in the car malfunction, the computer will generate fault codes, which can help technicians quickly determine the fault location and cause, and only then can the fault be quickly repaired. During regular maintenance, the technician can use a diagnostic computer to read the fault codes, allowing them to promptly know what issues exist in the car's electronic systems.
When encountering an error code on the center display screen, my first reaction is to stay calm and immediately refer to the vehicle's user manual. The manual usually contains explanations and solutions for fault codes. For example, displaying "E123" might indicate a software issue with the infotainment system—try holding the power button for a few seconds to reboot the center screen. If the code persists, check if the data cable connection is loose or oxidized. I've seen cases of screen distortion and code crashes, mostly caused by poor contact or incomplete software updates. In such cases, ensure the vehicle is parked securely, then unplug and reconnect the data cable or update the firmware via USB. If the situation worsens, with the code recurring or accompanied by other warnings, avoid DIY fixes and promptly contact a 4S店 technician to prevent short circuits or damage to larger components—safety first! Regularly check the system startup status before driving and have the service center inspect the interfaces during each maintenance visit to save a lot of hassle.
When I see an error code pop up on the center console screen, my old-school approach is to first stay calm and pull over safely. I immediately take out my phone to photograph the code, then flip through the owner's manual for explanations—for instance, 'P0887' might indicate an air conditioning control unit malfunction. A simple solution is to try restarting the vehicle engine; sometimes the system just acts up temporarily and returns to normal. If the problem persists, carefully check if the power or signal cable connectors are loose and try tightening them yourself. Don't push your luck—error codes may hint at wiring degradation or voltage instability, which could affect navigation functions over time. Safe driving demands caution. I recommend heading straight to a professional repair shop for diagnosis; their scanners can pinpoint the issue accurately, while DIY attempts might make things worse.
