What to Do When the ABS Light Comes On and the Car Won't Lock in a Baojun?

Baojun ABS faults can be checked based on the following aspects: 1. Conduct a visual inspection of the system to check for damaged wires, loose plugs, and low brake fluid levels. 2. Use a decoder to read and interpret fault codes to identify the fault conditions represented by the codes. 3. Based on the interpreted fault conditions, use necessary tools and instruments to conduct an in-depth inspection of the faulty parts to diagnose the fault location and cause. 4. If the warning light remains on, there may still be a fault in the system, or the fault may have been resolved but the fault code has not been cleared. Below is an introduction to the reasons why the ABS light comes on: 1. Issues with the ABS wheel speed sensor. The wheel speed sensor is located on the wheel and is easily contaminated by dirt or mud. If the sensor is covered with a large amount of dirt, it can affect the transmission of the speed signal. The ABS computer cannot determine the speed signal and will trigger an alarm. In this case, cleaning the dirt on the sensor and adjusting the gap between the sensor and the signal ring can resolve the issue. If the wheel speed sensor is damaged, it must be replaced. 2. Line connection faults, which are relatively common. Although all cars have ABS systems, the assembly quality and materials may vary due to different manufacturing processes. Loose connections in the wheel speed sensor wiring are quite common and should be checked thoroughly. Line troubleshooting can be tedious, so patience is required. It's best to inspect each plug, including the contact condition of related fuses and the grounding of the ground wire. 3. Issues with ABS control unit programming, likely due to mismatched or incorrect data within the control unit. The data needs to be readjusted, which requires a specialized diagnostic computer. 4. Problems with the ABS master cylinder. 5. Faults in the ABS control unit circuit board, requiring replacement of the computer. However, this type of fault is very rare.
Last time I drove a Baojun, I also encountered the ABS light turning on and the car not locking, which was quite scary. The ABS light coming on might indicate a potential issue with the braking system, such as sensor dust buildup or wheel problems, and not fixing it in time could affect braking. The locking issue could be due to the central locking getting stuck or a weak battery. I suggest not driving it immediately—try manually locking the doors with the key first, then check if the battery is low on charge, as low voltage can trigger various issues. If you can handle it yourself, cleaning the sensor contacts or checking the fuses in the fuse box could save some money. But safety comes first—it's best to drive to a nearby Baojun service center for a full inspection to prevent the problem from worsening. I've been through something similar, and fixing it promptly avoided major trouble.
