What is the SRS malfunction in BYD?

SRS refers to the airbag system. If the warning light is on, it indicates a malfunction in the airbag or seatbelt pretensioner system. Although this issue does not affect driving, in the event of an accident, the airbag may fail to deploy, providing no protection. Therefore, when the airbag warning light on the dashboard illuminates, it is recommended to promptly visit a 4S dealership for professional inspection and repair. Below are relevant details: SRS Airbag: The electronic airbag system is a passive safety protection system (refer to vehicle safety performance) that works in conjunction with seatbelts to provide effective collision protection for occupants. In a collision, car airbags can reduce head injuries by 25% and facial injuries by approximately 80%. Function: The airbag system is an auxiliary protective device made of special fabric nylon with a rubber lining, filled with harmless helium gas during operation. In a collision, the airbag inflates in about 0.03 seconds. This rapid inflation ensures that the airbag is in place in time when the passenger's body is restrained by the seatbelt while the head continues to move forward.
When the SRS light comes on while driving a BYD, I suspect it's a problem with the airbag system. The most common issue is a faulty sensor, such as a misaligned or dust-clogged crash sensor causing false alarms. It could also be due to aging or short-circuited wiring, loose or corroded connectors leading to signal interruptions. Another possibility is a problem with the airbag module itself, like an overheated or malfunctioning computer control unit or a software error triggering the warning. Sometimes, low or unstable battery voltage can also cause the system to falsely report a fault. Airbags are life-saving devices and should not be ignored! If the light comes on, it's best to visit a 4S shop or authorized repair center as soon as possible for a professional inspection to prevent protection failure in case of an accident. I've seen a friend's car turn a small oversight into a big problem, so don't procrastinate—safety comes first.
As a BYD owner, I was quite anxious when the SRS warning light came on. This is mostly a safety-related issue, simply put, the system self-check failed. Possible causes include a faulty weight sensor under the seat mistakenly thinking no one is seated, or worn wiring in the steering wheel airbag causing poor contact. Additionally, the light shouldn't stay on too long after starting the car; if it remains lit, it indicates a serious problem. I suggest everyone avoid tampering with airbag components and refrain from DIY repairs that might worsen the situation. Instead, drive directly to a professional shop to check diagnostic codes. Technicians can use computers to pinpoint the exact fault, such as whether a relay has blown or the control board is burnt. When washing the car, be careful not to get water into the connectors to reduce the risk of water damage affecting longevity. Early diagnosis brings peace of mind!
