What to Do When the ABS Light in Haima S5 Comes On?
2 Answers
Haima S5's ABS warning light may come on due to the following reasons: Reason 1: The ABS wheel speed sensor's sensing part is covered by mud, sludge, or other contaminants, affecting the sensor's ability to detect the corresponding vehicle speed signal. This prevents the ABS computer from determining the vehicle speed and the wheel slip rate, thus failing to issue appropriate commands to adjust braking. Solution: Clean the dirt on the wheel speed sensor and adjust the gap between the sensor and the signal gear ring to restore normal operation. Reason 2: Poor signal due to loose connections between system lines or poor contact of the ABS relay can cause system failure. The most common issue is a loose connection of the wheel speed sensor wire, which will also display a poor wheel speed sensor signal in the ABS computer's fault memory. Solution: Check the line connections and reconnect any loose parts.
When driving my Haima S5, the ABS light came on a few times. I remember once when I went out on a rainy day, the light suddenly turned on, which made me panic, but I quickly pulled over to check. First, I turned off the engine and restarted the car to see if the light went off; if it was still on, it might be because the wheel speed sensor got muddy or wet—that thing is located inside the wheel and easily accumulates dust. If the ABS malfunctions, the brakes may skid, especially on slippery roads, making it even more dangerous. I checked the fault code with my phone and found it was a left front wheel sensor open circuit. Later, I went to the 4S shop to replace it with a new one, which fixed the issue. Don’t neglect cleaning the chassis while driving normally; regularly blow off the sensor area to prevent dust buildup and false alarms. Safety is no trivial matter—if the light comes on, slow down and avoid speeding, and get it repaired at a professional shop as soon as possible to prevent major trouble.
