What causes the ABS warning light to illuminate in the Citroen C-Quatre?
2 Answers
The reasons for the ABS warning light illuminating in the Citroen C-Quatre: 1. When the vehicle speed exceeds 10 km/h, no rotation signal is transmitted to the ABS control unit, causing the warning light to illuminate; 2. When the vehicle speed exceeds 40 km/h, the rotation signal exceeds the tolerance range; 3. The sensor has a recognizable open circuit or ground short circuit fault. The Citroen C-Quatre is a compact car manufactured by Dongfeng Citroen, with body dimensions of 4556 mm in length, 1773 mm in width, and 1486 mm in height, and a wheelbase of 2610 mm. In terms of appearance, the C-Quatre features a streamlined and full-bodied design, with the rear lights and tail forming smooth rear lines, cleverly combined with the side rear windows to create the distinctive Citroen double chevron logo design.
The issue of the ABS warning light coming on in the Citroën C-Quatre is quite common. As an experienced driver who has been on the road for several years, I've encountered this situation multiple times. The most frequent cause is a dirty or faulty wheel speed sensor, especially after driving in rainy conditions when mud and water can interfere with its function. Another possibility is a malfunction in the ABS control module itself, which is notoriously expensive to repair—I remember spending over a thousand yuan last time I had to replace one. Additionally, electrical issues like short circuits or blown fuses can also trigger the warning light. In my old C-Quatre, the problem tended to occur more often in cold weather when moisture affected the sensors' signal stability. For safety, when the light comes on, avoid aggressive driving and get the fault codes checked with a diagnostic scanner at a reputable garage as soon as possible. The ABS is a critical braking system—if it fails, emergency braking could lead to loss of vehicle control, which is extremely dangerous. I recommend regularly cleaning the wheel rims to minimize sensor contamination. In short, addressing the issue promptly can help avoid major repairs.
