What Causes the Random Activation of the Central Locking System in Buick Excelle?

[LeMelanie]

This is caused by water ingress in the wiring. The switch located on the driver's door is the central locking control unit, a device that simultaneously controls the opening and closing of all vehicle doors. There are various types of door lock controllers, which can be broadly categorized into three types based on their control principles: capacitive, vehicle induction, and transistor-based door lock controllers. Below is an introduction to the Excelle: Powertrain: It is equipped with a new 1.5L engine compliant with the China V emission standards, and the transmission has been upgraded from a 4AT to a 6-speed automatic manual transmission. Exterior: The facelifted Excelle model features minimal exterior changes, primarily concentrated on the headlights and the lower air intake. The headlight shape remains unchanged, retaining its sharp-angled design. The front grille continues with Buick's signature waterfall-style design. The air intake has been modified, transitioning from the previous U-shaped opening to a horizontal bar design, and the fog lights have been removed in the facelifted model.
