Why is the ABS yellow light on in Venucia?

[JocelynRose]

When the ABS light is displayed on the car, it indicates a malfunction in the vehicle's anti-lock braking system. During emergency braking, if the wheels lock up, the vehicle may lose control and skid, making it difficult for the driver to slow down or adjust the vehicle's trajectory, posing a significant safety hazard. There are several states in which the ABS light may illuminate, with different causes and solutions for each state, as detailed below: State 1: ABS warning light stays on (most common). Cause 1: The ABS wheel speed sensor's sensing area is covered by dirt, mud, or other contaminants, affecting the sensor's ability to detect the corresponding speed signal. This prevents the ABS computer from determining the vehicle speed and the wheel slip rate, thus failing to issue appropriate commands to regulate braking. Solution: Clean the dirt from the wheel speed sensor and adjust the gap between the sensor and the signal ring to restore normal function. Cause 2: Loose connections in the system wiring or poor contact in the ABS relay can lead to signal issues and system failure. Solution: Check the wiring connections and reconnect any loose parts. State 2: ABS warning light intermittently illuminates but turns off during acceleration. Cause: When multiple vehicle electrical devices are in use, the battery voltage may drop below 10.5V. As the engine speed increases and the voltage rises, the ABS light turns off. This can also occur if the ABS system's power supply voltage is too low due to poor contact or grounding issues. Solution: Check the battery's specific gravity, inspect the charging system, and examine the power supply (e.g., voltage relay or poor power contact). State 3: ABS warning light stays on after engine start and only turns off when the engine is turned off (IGFF). Cause: Poor grounding contact in the ABS hydraulic valve body, loose wiring connections in the ABS hydraulic valve body, or a faulty ABS computer. Solution: Loosen and then retighten the grounding screw on the hydraulic valve body, cleaning the contact surface if necessary. Check if the connector gaps have widened. Replace the ABS or ABS/ASR computer if needed. State 4: ABS warning light illuminates during high-speed driving. Cause: At high speeds, the ABS computer detects a significant discrepancy between the rear and front wheel speed signals. This may also occur due to incorrect tire or wheel rim specifications. Solution: Refer to the vehicle's tire and wheel rim specifications, as indicated on the sticker near the fuel tank cap. State 5: ABS warning light intermittently illuminates. Cause: Improper adjustment of the brake light switch or poor internal contact in the brake light. Solution: Start the engine, press the brake pedal, and use a finger to push the brake switch linkage all the way down. Release the brake pedal to complete the self-setting position. Replace the brake light switch if necessary.

I've encountered the Venucia ABS yellow warning light several times, which usually indicates an issue with the anti-lock braking system. The most common causes are a dirty or damaged wheel speed sensor where dust accumulation interferes with the signal, or problems with the ABS module such as water ingress or aged wiring causing short circuits. Sometimes it's simply a blown fuse or low brake fluid triggering the warning. ABS failure compromises braking safety, especially on slippery surfaces where tires may lose traction, increasing accident risks. When this light appears, promptly pull over to check basic items like fuses and sensor cleanliness, but ultimately you must visit a professional repair shop for diagnostic code reading and proper resolution without delay.

The ABS yellow light on the Venucia is definitely a problem. As someone who drives frequently, I believe this is urgent and shouldn't be delayed. The ABS is a life-saving system that prevents wheel lock-up during braking. The light being on means the system has failed, potentially leading to longer braking distances or even loss of control. There could be multiple reasons: a faulty wheel speed sensor, a loose or mud-covered sensor, a malfunctioning controller or poor wiring connection, or even unstable battery voltage triggering the warning. If you want to check it yourself, first inspect the ABS fuse in the fuse box to see if it's intact, or try restarting the vehicle for a self-check. But safety comes first—don't risk continuing to drive. It's best to go to a 4S shop or a reliable repair shop immediately for a comprehensive diagnosis.

I found that when the Venucia ABS yellow light is on, it usually indicates a system alarm issue. Common problems include false alarms caused by sensor dust accumulation, ABS module circuit failure, or related wire insulation damage leading to a short circuit. You can perform simple troubleshooting yourself, such as cleaning the sensor probes near the wheels with a soft cloth and checking if the fuses are intact. However, if the light remains on, it's necessary to visit a professional repair shop for code reading and diagnosis. Don't take it lightly, as ABS failure can lead to reduced braking efficiency and compromise driving safety.

To prevent the ABS yellow light issue on the Qichen, I usually pay attention to maintenance to reduce risks. The ABS light typically comes on due to dirty sensors, a burnt-out module, or wiring problems; this can make the braking system unstable, especially in rainy or snowy weather, which is dangerous. Daily maintenance should include regularly cleaning dust buildup in the wheel area and ensuring the brake fluid is sufficient without leaks. If the light flashes, immediately check the fuses and for loose plugs; if the issue persists, go for repairs. Developing good habits can prevent many faults, saving money and ensuring safety.
