What is the issue when PRE-SAFE stops functioning
3 Answers
PRE-SAFE stops functioning under the following circumstances: 1. Normal situation: If PRE-SAFE stops functioning under normal circumstances, it does not affect the vehicle's operation. The driver can restore normal function by turning off the engine and restarting it. 2. Sensor malfunction: In special cases where it cannot be activated, it may be due to a sensor malfunction. It is recommended to take the vehicle to a 4S shop for inspection and check if the car radar needs cleaning; it is also possible that the camera sensor was damaged during car washing. 3. Safety protection device turned off: Additionally, PRE-SAFE stopping functioning could be due to the vehicle's safety protection device being turned off, meaning the passenger airbag switch is deactivated. The owner can go to a service station for assistance or manually turn on the passenger airbag themselves, with the switch located on the passenger side. If none of these issues are present, the owner can choose to upgrade the computer system and then clear the fault code.
The Pre-SAFE system has stopped working. I guess you might have noticed it's unresponsive while driving. This system primarily relies on sensors to monitor risks, such as automatically tightening seat belts or closing windows when the radar detects a potential frontal collision. Common issues include sensor malfunctions—if the radar cover is covered in mud or scratched, signals can't get through. Electrical problems are also frequent, like blown fuses or aged wires causing short circuits that interrupt the connection. Software glitches are another possibility; bugs may appear over time, requiring a firmware update. Additionally, low battery voltage can cause the system to falsely report a shutdown. In short, don’t take it lightly—when this system is off, your protection in emergencies is compromised. It’s best to visit a professional shop ASAP to scan for error codes with a diagnostic tool and identify the root cause before an accident happens. Repairs are usually straightforward, like replacing a sensor or a fuse, typically costing a few hundred bucks.
Pre-SAFE suddenly malfunctioned? That's quite distressing—I've experienced a similar situation before. One night while driving on the highway, the system displayed an error, and my heart immediately skipped a beat. Once it stops working, all the protective mechanisms fail, like the seatbelts not tightening in advance during emergencies. There are various possible causes: dirty or misaligned sensors triggering false alarms; the system's computer module overheating or short-circuiting, especially during high summer temperatures; loose wiring connections; or an unstable car battery voltage triggering error warnings. I think it's best to first check if the sensors are clean yourself, then use an OBD tool to read the fault codes. If you're not familiar with these, avoid driving long distances to prevent risks—it's safer to visit a professional repair shop, as driving safety comes first. During regular maintenance, have them check the system to prevent issues.
