So-called eABS does not actually have the real ABS anti-lock function, but is actually the so-called "e-brake", which is an electric brake. The ABS system mainly consists of 4 parts: wheel speed sensor, electronic control unit ECU, hydraulic unit, and ABS fault light. The wheel speed sensor detects the motion state of the wheels and sends out a sine wave electronic pulse AC signal, which is then processed by the modulator, converting the pulse into a digital signal and transmitting it to the electronic control unit. The electronic central control unit ECU receives the input signal from the wheel speed sensor, calculates the wheel speed, vehicle speed, and slip rate based on this parameter, judges the wheel state according to the slip rate, and issues control commands to the hydraulic unit. The hydraulic unit adjusts the pressure of the brake pipeline according to the control commands, and the adjustment process includes pressure holding, pressure increasing, and pressure reducing. The ABS fault light is used to alert the driver whether the system has a fault.

Where is the coolant temperature sensor located in the Tiguan?

Tiguan's coolant temperature sensor is located inside the front bumper of the engine, in direct contact with the coolant. The lower the internal temperature of the coolant temperature sensor, the greater its resistance. It is used to measure the temperature of the engine's coolant, with the thermostat generally maintaining a temperature of 90 degrees. Additional information: 1. Principle of the coolant temperature sensor: The electronic control unit (ECU) detects the engine coolant temperature based on this change - the lower the temperature, the higher the resistance, and vice versa. The ECU uses this change to measure the engine coolant temperature as a correction signal for fuel injection and ignition timing. The engine coolant temperature can indicate the vehicle's operating status, whether it is stationary or moving, or how long it has been running. 2. Structure of the coolant temperature sensor: The automotive coolant temperature sensor is installed in the water jacket of the engine block or cylinder head, in direct contact with the coolant, to measure the engine's coolant temperature. The temperature sensor used in the coolant temperature gauge is a negative temperature coefficient thermistor (NTC), whose resistance decreases as the temperature increases, with one wire connected to the ECU.

Additionally, after missing the exam, you must wait for several working days before you can reschedule. Below is relevant information about Subject 1: 1. Rescheduling after missing Subject 1: After missing the Subject 1 test, the vehicle management office's system needs to record the results, including the absence, which takes approximately ten working days. After this period, you can log into the 12123 traffic management app to reschedule. If the system hasn't updated after ten working days, you can contact your driving school or the local vehicle management office for assistance. 2. Subject 1: Also known as the theoretical test or driver's theory test, it is part of the motor vehicle driver's license examination.

What are the reasons for the Baojun 730's automatic locking?

The reasons for the Baojun 730's automatic locking are remote control failure, controller malfunction, or poor line contact. Here are the relevant details: 1. Remote control failure: The remote control is damaged, causing it to malfunction, which in turn leads to automatic locking. The remote control is prone to damage if dropped from a height or if it gets wet, as the internal circuits may burn out, rendering the remote control unusable. Additionally, magnetic interference can also affect the remote control's functionality, so it's best to avoid placing it near items like computers. Solution: Repair or replace the car key. 2. Controller malfunction: Improper long-term use can cause issues with the central locking module, leading to automatic locking. The central locking module specifically controls automatic locking, and if it malfunctions, symptoms like automatic locking may occur. Solution: Replace the central locking module promptly or have it inspected at a 4S shop. 3. Poor line contact: The wiring is very complex, and even with diligent maintenance, problems can arise over time. Wiring can age due to prolonged use, leading to poor contact and resulting in automatic locking. Solution: Replace the wiring.
