What causes the central locking system of Excelle to jump?
2 Answers
The reasons for the central locking system of Excelle jumping are: 1. Water ingress in the wiring; 2. Damage to the central locking control unit; 3. Damage to the central locking system. To address the jumping issue in the Excelle's central locking system, it is necessary to visit a 4S dealership to replace the door lock control assembly and the central control module. The central locking system, fully known as the central control door lock, is an automotive component composed of the door lock switch, actuator, and controller. Taking the Excelle 2020 model as an example, its body dimensions are: length 4468mm, width 1765mm, height 1469mm, with a wheelbase of 2611mm. The Excelle 2020 is equipped with a 1.3L naturally aspirated engine, delivering a maximum power of 79kW and a maximum torque of 133Nm, paired with a 5-speed manual transmission.
The intermittent operation of the Buick Excelle's central locking system is usually caused by internal mechanical component jamming or circuit failure. My car experienced a similar issue where the latch would continuously cycle back and forth. It was later found that accumulated dust or rust inside the lock mechanism caused the spring to stick, preventing proper locking. This could also result from poor circuit contact in the central control module, such as short circuits due to aged wiring or unstable relay operation. During daily driving, bumpy roads or temperature fluctuations may exacerbate this problem. When encountering this situation, first check the remote control battery - insufficient power can affect signal transmission, or test by holding down the manual button on the door. If unsuccessful, professional repair is recommended to prevent further component damage. During routine maintenance, remember to lubricate the lock mechanism to extend its service life.
