What are the causes of BYD Song ESP system failure?
2 Answers
BYD Song ESP system failure is caused by a malfunction in the vehicle's traction control system, which requires timely inspection and repair. Below is a detailed introduction about automotive repair: 1. Overview: Automotive repair is a general term for vehicle maintenance and repair. It involves using technical means to diagnose a faulty vehicle, identify the cause of the malfunction, and take certain measures to eliminate the fault and restore the vehicle to a certain level of performance and safety standards. 2. Others: Automotive repair includes major repairs and minor repairs. Major repairs refer to restorative repairs that use methods such as repairing or replacing any vehicle components (including fundamental parts) to restore the vehicle's proper technical condition and fully (or nearly fully) recover its lifespan. Minor repairs refer to operational repairs that use methods such as replacing or repairing individual parts to ensure or restore the vehicle's operational capability.
I often repair various cars, and there are quite a few reasons for the ESP system failure in the BYD Song. Generally speaking, sensors are the main culprit. The wheel speed sensor can easily be covered by mud or oil, leading to inaccurate signals, which triggers the warning light. Wiring issues are also common, such as loose connectors or short circuits from damaged wires. The BYD Song's chassis position is prone to debris affecting the wiring. Control system failures, like bugs in the computer module or poorly updated software, can cause incorrect commands. Another point is a blown fuse or unstable battery voltage, which affects the entire system's power supply. There's also relay aging or mechanical wear, causing delayed responses. In short, once the ESP light comes on, immediately stop and go to a professional shop to check the fault codes with a diagnostic tool—never overlook driving safety.
