How is the electronic handbrake off and on?
The switch mode of the electronic handbrake is similar to the operation mode of the electric lift window, most cars are pulling up the electronic handbrake button to pull the handbrake, and pressing down is to put down the handbrake.
The electronic handbrake is a common automotive equipment, and its structure is different from the traditional robotic brake.
The traditional manipulator brake is composed of a handbrake pull bar and a handbrake pull wire, while the electronic hand brake does not have these parts.
The rear wheel of a car equipped with electronic handbrakes has two handbrake motors that push the brake pads, thereby clamping the brake discs.
The use of the electronic handbrake is very convenient, and the driver does not need to pull the handbrake lever.
Many cars with electronic handbrakes also come with the autohold function, which is very practical.
The autohold function can be used while waiting at a red light or while stuck in traffic.
When the red light is on, after the autohold function is activated, the driver does not need to pull the handbrake, hang n gear or always step on the brake, the car can stay in place.
When the red light turns green, the driver simply presses the accelerator pedal and the car moves forward.
In traffic jams, autohold is especially suitable for use on urban roads with lots of traffic lights and congestion.
If you are interested, you can go to experience this feature.
The performance of the electronic handbrake switch bad mainly includes the handbrake switch fault, handbrake light line poor contact, handbrake instrument display light poor contact and insufficient battery power supply.
Handbrake switch failure: When it is suspected that the handbrake switch is faulty, can be confirmed by removing the handbrake housing, use a multimeter to test the voltage of the switch. If an abnormal voltage is found this indicates that the handbrake switch may be faulty. The solution to this problem is to replace the handbrake switch with a new one.
Poor contact of handbrake light line: by using a multimeter to detect whether the voltage of the red line is normal, can initially determine whether there is poor contact. If an anomaly is found, requires further examination of the specific areas where poor contact may have occurred.
Poor contact of handbrake instrument display light: if the problem is caused by poor contact of handbrake instrument display light, can first turn off the handbrake switch, observe whether the fault is still displayed. if the fault is still, may be the instrument has a problem, at this time to replace the instrument is one of the solutions, although the price is higher, will not affect the normal use of the electronic handbrake.
Insufficient battery power: electronic handbrake display system failure may also be due to insufficient battery power. In this case, needs to go to the repair shop to read the fault code with the decoder, and then repair according to the fault code.
In summary, the failure of the electronic handbrake switch can be diagnosed and resolved by detecting the voltage of the handbrake switch, checking the contact of the handbrake light line, observing the handbrake instrument display light and checking the battery power supply.
Electronic handbrake switch is broken how to manually release?
When the electronic handbrake switch is broken, you can try the following methods to manually release the electronic handbrake:
Step on the accelerator: Restart the vehicle, shift the gear to D gear, step on the accelerator pedal, the electronic handbrake may automatically release.
Press the button: After starting the vehicle, step on the brake pedal and press the electronic handbrake button down to force the electronic handbrake to be unlocked.
Replace the switch: If the switch of the parking brake fails to open the electronic handbrake, the switch of the parking brake needs to be replaced at this time.
Maintenance line: If the line between the switch of the parking brake and the control unit is in poor contact or there is a short circuit, the damaged circuit needs to be repaired in time.
Pull out the release line: In the bottom left corner of the suitcase, behind the taillight, there is a handbrake emergency manual release line, hard pull out this line can be successfully unlocked.
4S shop maintenance: Send the vehicle to the 4S shop, read the fault code, and then repair, you can unlock the electronic handbrake.
If the above methods cannot solve the problem, it is recommended to contact professional technicians for inspection and maintenance to ensure the safety and normal use of the vehicle.
