What Causes the ABS Yellow Light to Illuminate in a Car?

ABS light illumination can occur in various states, with different causes and solutions for each state. The details are as follows: State 1: ABS warning light stays on constantly (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 wheel slip rate, thus failing to issue appropriate commands to adjust 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: Poor signal due to loose connections between system wires or poor contact of the ABS relay, leading to system failure. Solution: Check wire connections and reconnect any loose parts. State 2: ABS warning light illuminates intermittently and turns off when accelerating. Cause: When multiple vehicle electrical devices are in use, the battery voltage drops below 10.5V. As the engine speed increases, the voltage rises, causing the ABS indicator to turn off. This may also occur if the ABS system power supply voltage is too low due to poor terminal contact or grounding issues. Solution: Check the battery's specific gravity; inspect the charging system; 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 of the ABS hydraulic valve body; poor contact of the ABS hydraulic valve body wire connector; ABS computer malfunction. Solution: Loosen and retighten the grounding screw of the hydraulic valve body, cleaning the contact surface if necessary; check if the connector gap has widened; replace the ABS or ABS/ASR computer. 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; incorrect tire or wheel rim specifications. Solution: Refer to the vehicle's tire and wheel rim specifications, as indicated on the label near the fuel tank cap. State 5: ABS warning light illuminates intermittently. Cause: Improper adjustment of the brake light switch; poor internal contact of the brake light. Solution: With the engine running, press the brake pedal and use a finger to push the brake switch linkage down fully, then release the brake pedal to complete the self-setting position; replace the brake light switch if necessary. If the ABS warning light is on, it is advisable not to continue driving. An illuminated ABS light indicates a malfunction in the vehicle's anti-lock braking system. During emergency braking, if the wheels lock up, the vehicle may skid uncontrollably, preventing the driver from slowing down or adjusting the vehicle's trajectory, posing significant safety risks.

What to Do If Driving License Training Hours Are Insufficient?

If the required training hours have not been recorded, you should promptly go to the driving school to make up the missing hours for the corresponding subject. Only after review and approval can you schedule the exam. Some driving schools do not strictly enforce the recording of training hours due to the lack of linkage between training attendance and exam scheduling, as well as network failures, which has left many unable to schedule their exams.

What to do if the three-year validity period for obtaining a driver's license has expired without passing?

If you have already passed Subject 1 but haven't completed Subject 2 or Subject 3, your records will be cleared regardless, and your file will be canceled. If you haven't even taken Subject 1, then the validity period hasn't been exceeded. In this case, you should check whether the contract signed with the driving school specifies a time limit.

What to Do If Your Legs Shake During the Driving Test?

Students should engage in mental preparation, such as listening to soothing music or practicing positive self-affirmations, to alleviate nervousness. During the test, students should treat it as a regular driving practice session, avoiding excessive self-expectations and maintaining a calm mindset to perform better. If sudden nervousness arises during the test, students can try deep breathing and remind themselves internally that it's just a normal practice session.
