Why does the Changan Eado's side slip light illuminate and the car fail to accelerate?

The reasons why the Changan Eado's side slip light illuminates and the car fails to accelerate are: 1. Accidentally pressing the ESP off button; 2. Loose or faulty sensor connectors; 3. Short circuit in the wiring or related fuse blown; 4. Software issues causing poor signal transmission; 5. ABS pump failure. Taking the Eado 2021 PLUS Blue Whale NE1.4TGDIDCT Premium model as an example, it is a compact car launched by Changan Automobile, with a length, width, and height of 4730mm, 1820mm, and 1505mm respectively, and a wheelbase of 2700mm. It is equipped with a 1.4T turbocharged engine, with a maximum power of 118kw and a maximum torque of 260nm, matched with a 7-speed dual-clutch transmission.
When I encountered the issue of the Changan Eado's side slip light illuminating and inability to accelerate, my first thought was that the system had entered protection mode. The side slip light typically indicates the activation of the Electronic Stability Program (ESP), which could be due to the wheel speed sensor detecting abnormal rotation in a particular wheel—perhaps because the sensor was covered in dirt or malfunctioned, prompting the engine to automatically limit acceleration to prevent skidding. Another common cause is a faulty ABS control unit or poor wiring contact, which signals the engine ECU to reduce power output. For troubleshooting, you can start by turning off the engine and restarting it, which might temporarily restore normal function. If that doesn’t work, a diagnostic tool should be used to read the fault codes and pinpoint the specific issue, such as whether the sensor needs cleaning or replacement. Ignoring ESP problems can lead to side-slip accidents, especially on slippery roads, so I advise against forcing the car to drive and recommend visiting a 4S shop for inspection as soon as possible to prevent accidents. Regularly cleaning around the wheels can prevent sensor blockages, and simple maintenance like this can reduce such faults.
