Parking sensor button: Turns the car's parking sensor system on or off; 3. Central locking button: Controls the central door locking system of the vehicle; 4. Rear sunshade button: Opens or closes the electric rear sunshade inside the car; 5. Headlight washer button: Controls the automatic cleaning function of the headlights.

Working Principle of a Four-Wire Brake Light Switch?

Four-wire brake light switches essentially consist of two switches in one: a normally open (NO) switch and a normally closed (NC) switch. When the brake pedal is pressed, the normally open switch closes (conducts), while the normally closed switch opens (stops conducting). Below are details regarding four-wire brake light switches: 1. Overview: A four-wire automotive brake light switch has one 12V power supply wire, two wires sending brake signals to the ABS system ECU and automatic transmission ECU respectively, and another wire leading to the rear brake indicator light. In some high-end models, the ABS and automatic transmission share a single wire, with an additional wire added for electronically controlled suspension brake signals. Thus, apart from the power wire, all other wires on the brake light switch connect to control units requiring brake signals, while the rear brake indicator is controlled by the vehicle's lighting system. 2. Testing Method: To check the functionality of a four-wire brake light switch, a multimeter is required. Set the multimeter to the diode test mode. Use the red and black probes to measure between the pins. If any two pins show continuity, they are the normally closed contacts. The remaining two pins are the normally open contacts.

What is the reason for the car not starting and making abnormal noises?

The battery is faulty and cannot store power. If you can only hear the sound of the starter when trying to start the car, it is likely that the battery is dead and unable to start the car. The starter motor may also be faulty and unable to turn the flywheel. Check if the starter motor is working when attempting to start the vehicle. The reasons for the car not starting and making a clicking sound are as follows: 1. First scenario: If the car initially starts without issues but the starting time gradually increases until it suddenly fails to start one day, this is likely due to a problem with the engine's ignition system or fuel supply system. In this case, it is necessary to seek professional repair services. 2. Second scenario: If the car has always started well but suddenly fails to start one day, it is likely a battery issue, where the battery is dead and cannot supply power normally. 3. Third scenario: If the headlights can function normally, it is mostly due to an open circuit in the protective coil of the starter motor's solenoid switch.
