What does it mean when the ABS warning light comes on in a vehicle?

When a car displays ABS, it indicates a malfunction in the vehicle's anti-lock braking system. If the wheels lock up during emergency braking, the vehicle may lose control and skid, preventing the driver from slowing down or adjusting the vehicle's trajectory, which poses significant safety risks. There are several states in which the ABS light may illuminate, each with different causes and solutions, as detailed below: State 1: ABS warning light stays on continuously (most common). Cause 1: The ABS 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's speed and the wheel slip rate, thus failing to issue appropriate commands to regulate braking. Solution: Clean the dirt from the speed sensor and adjust the gap between the speed sensor and the signal ring to restore normal function. Cause 2: Poor signal transmission due to loose connections between system wires or poor contact in the ABS relay, leading to system failure. Solution: Inspect wire connections and reconnect any loose parts. State 2: ABS warning light intermittently illuminates but turns off when accelerating. Cause: When multiple vehicle electrical devices are in use, the battery voltage may drop below 10.5V. As the engine speed increases and voltage rises, the ABS warning light turns off. This may also occur if the ABS system's 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 in the ABS hydraulic valve body; poor contact in the ABS hydraulic valve body's wire connector; ABS computer malfunction. Solution: Loosen and then retighten the grounding screw on 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: During high-speed driving, 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 intermittently illuminates. Cause: Improper adjustment of the brake light switch; poor internal contact in the brake light. Solution: With the engine running, press the brake pedal, push the brake switch linkage down fully with your finger, then release the brake pedal to complete the self-setting position; replace the brake light switch if necessary.

What documents are required for Volkswagen's first maintenance?

Documents required for the first maintenance include: driver's license; vehicle registration certificate; maintenance manual; warranty manual; owner's ID card; vehicle's driving license; vehicle purchase invoice, to be taken to the designated first maintenance institution for the vehicle's initial service. Important note: make an appointment with the 4S store in advance. The first maintenance refers to the initial service after the new car has been driven, with the specific time varying by vehicle, generally after driving 1,000 to 3,000 kilometers. The car must attend the first maintenance on time, neither earlier nor later. The completion of the first maintenance marks the end of the car's break-in period, allowing it to be driven according to the standard load and normal speed required by the vehicle. The timing of the first maintenance is calculated based on the date of vehicle pickup. There are two indicator values for the first maintenance: mileage and time. Whichever comes first will be the standard. First maintenance items include: changing the engine oil and oil filter, cleaning the air filter, checking various oil levels for normality, inspecting the generator belt and wiper blades for damage, checking tire pressure for normality, and examining tires for damage or bulges. Estimated time required: approximately 2 hours to complete all tasks. The most crucial aspect of the first maintenance for a new car is changing the engine oil and oil filter. When changing the engine oil, the oil filter must also be replaced simultaneously. The selection of engine oil must refer to the "Vehicle Usage and Maintenance Manual," as different vehicle models specify different engine oil grades. Maintenance precautions: Do not rinse the interior of the car body with water: Many people clean their cars themselves during holidays, washing the body with water and wiping it with a cloth. Here, it is important to remind that the interior of the car body should not be directly washed with water. If the floor mats are dirty, you can use a vacuum cleaner or take them out, clean them with a brush and detergent, dry them, and then put them back. There are many through-holes under the rubber mats on the floor of the driver's compartment. If water enters, it will not dry by air but will flow through the holes to areas like the gearbox, causing erosion and corrosion. The better practice is to clean with a vacuum cleaner and then wipe with a cloth to prevent water accumulation. Do not mix different brands of antifreeze: When the antifreeze in the car is insufficient, it is recommended to drain the antifreeze first and then add the same brand of antifreeze from the beginning. Since antifreeze brands differ, their chemical functions vary significantly. Various functional corrosion inhibitors can corrode others. Different brands of antifreeze use different corrosion inhibitors, so they should not be mixed to avoid unnecessary trouble. Do not lubricate tire bolts and nuts: When bolts on a moving car rust, they are often oiled to function properly again. To prevent the bolts and nuts on the wheels from rusting, some people apply lubricating oil to them, which poses a necessary risk to safe driving. When the car is driven at high speed, the bolts and nuts can be easily loosened or even fall off, leading to driving failures. Do not press the accelerator when starting an EFI car: The starter of an EFI car is different from that of a regular car. Its fuel injection control device can automatically adjust the fuel supply based on the starter's temperature and working conditions, ensuring a smooth start.
