ACC calibration requires diagnostic instruments for matching. Before installation, the ACC needs to be installed horizontally, followed by vehicle matching. The operation is relatively professional, so it is recommended to go to a 4S shop for the procedure. If the car owner can handle it themselves, they may also perform the operation. Below is relevant information about ACC calibration: Precautions during calibration: ACC calibration requires a set of specialized calibration tools. Following the prompts from the dedicated computer, there generally shouldn't be major issues. However, attention should be paid to whether the probe is dirty or if the probe mount is loose, etc. It is recommended to go to a 4S shop for calibration. Overview of ACC: Adaptive Cruise Control (ACC) does not appear to be much more advanced than regular cruise control, but its implementation is far more complex. It requires the installation of a distance-measuring radar at the front of the vehicle to determine the distance from the car ahead and transmit the data to the vehicle's computer for calculation. It can control the throttle and braking system of the vehicle when the car ahead accelerates or decelerates, maintaining an appropriate and safe distance from the car ahead.

Whether for the entire vehicle or individual components, they are guaranteed to be original factory products, ensuring consumers have no concerns about after-sales service, repairs, or maintenance.

What Causes the Wiper to Wipe Automatically?

Analysis of Automatic Wiping Causes: Accidentally touching the window washer switch may cause the wiper motor to operate for about 3 cycles as set to clean the glass; the car is equipped with an automatic rain-sensing sensor, and if the sensor malfunctions, it may mistakenly detect heavy rain and activate automatically; a short circuit in the wiper switch circuit may directly connect to the wiper motor, causing it to operate continuously and requiring inspection of the related wiper circuit. Solutions: When turning off the wiper, be cautious. If it does not stop at the initial position, stopping it immediately may block the view and affect driving safety; if the car is equipped with an automatic rain-sensing sensor and the sensor malfunctions, the rain sensor or its wiring needs to be replaced or repaired; the wiper control is managed by the body control module, and if the body control module program malfunctions and sends incorrect commands, the body control module needs to be inspected and repaired.
