Audi A4L reversing radar does not sound for the following reasons: 1. Buzzer failure. 2. Radar sensor damage. 3. Parking brake system malfunction. Extended information: 1. Reversing radar: When reversing, the reversing radar uses the principle of ultrasound. The probe installed on the rear bumper sends ultrasonic waves to hit obstacles and reflects these sound waves, calculating the actual distance between the vehicle body and the obstacle, prompting the driver to make parking or reversing easier and safer. 2. Main functions: (1) Accurately measure the distance between the rear of the car and the nearest obstacle. (2) When reversing to the limit distance, it can emit a rapid warning sound to remind the driver to pay attention to braking. (3) It can repeatedly emit a voice warning sound to remind pedestrians to pay attention.

How to Find the Positive Terminal of the Turn Signal?

To locate the positive terminal of the turn signal, follow these steps: 1. Turn on the turn signal; 2. Use a multimeter to systematically check for a 12V voltage with a regular on-off pattern—this will be the positive wire for the left and right turn signals. The turn signal is a frequently used light by drivers, clearly indicating the intended direction of travel to surrounding vehicles. In a car, the turn signal is located on the left side of the steering wheel. When needing to signal a turn, move the light lever up or down—up for the right turn signal and down for the left. Specific situations requiring the use of turn signals include: 1. Overtaking; 2. Changing lanes; 3. Making a U-turn; 4. Exiting a roundabout; 5. Pulling over to park; 6. Entering a highway.

How to Solve Rear Wheel Locking After Releasing the Handbrake?

The solutions for rear wheel locking after releasing the handbrake are: 1. Force start by stepping hard on the accelerator; once the rear wheels move, the locking can be released. 2. Remove the tire and tap the brake drum with a hammer or similar tool to loosen the contact surface between the brake drum and the brake pads. The reasons for rear wheel locking after releasing the handbrake include: 1. The car's handbrake cable not retracting; 2. The car's brake caliper not retracting; 3. The brake friction pads being frozen. Other situations of car wheel locking include: In cars without ABS, if the brake pedal is pressed hard while driving, the wheel speed will rapidly decrease. When the braking force exceeds the friction between the wheel and the ground, the wheel will lock. A completely locked wheel reduces the friction between the tire and the ground, and in severe cases, dangerous phenomena such as skidding, fishtailing, and sudden spinning may occur.

How to adjust the auto-lock function for Vios?

The Vios does not come with an auto-lock function. If needed, you can only have it installed at a professional modification shop or a 4S store. The auto-lock function is very practical, designed to prevent passengers from accidentally opening the doors while the vehicle is in motion, which could pose a danger. The Vios is positioned as a compact car, with dimensions of 4420 mm in length, 1700 mm in width, and 1490 mm in height, and a wheelbase of 2550 mm. In terms of power, the car is equipped with a 1.3L inline 4-cylinder naturally aspirated engine and a 1.5L inline 4-cylinder naturally aspirated engine. The 1.3L engine delivers a maximum power of 73 kW, 99 horsepower, and a maximum torque of 123 Nm. The 1.5L inline 4-cylinder naturally aspirated engine is paired with either a 5-speed manual or CVT transmission, producing a maximum power of 79 kW, 107 horsepower, and a maximum torque of 140 Nm.

Why is the Tachometer Not Moving?

The reasons why the tachometer is not moving: 1. The flexible shaft connection inside the tachometer is broken; 2. The tachometer needle has fallen off or is stuck; 3. There is a foreign object inside the instrument panel; 4. There is an issue with the wiring inside the tachometer, such as aging or burning out. The solutions for a non-moving tachometer are: 1. Replace the flexible shaft connection inside the tachometer; 2. Reinstall the tachometer needle; 3. Clean the foreign object inside the instrument panel; 4. Replace the wiring inside the tachometer. The tachometer is an instrument used to measure the engine's speed and is one of the essential tools in the mechanical industry, used to determine the motor's speed, linear velocity, or frequency. The tachometer receives digital pulse signals, processes them, and directly reads them into the CPU's counting port. The software then calculates the speed and the corresponding position of the needle. Through the CPU's control port, the signal is amplified to drive the stepper motor to rotate in positive or negative directions, indicating the corresponding speed value.
