What Causes the Constant Alarm in a Buick Excelle?

[SanGia]

There are many reasons why a Buick Excelle may constantly alarm, detailed analysis is as follows: 1. The anti-theft system sensitivity is set too high. 2. The sensor under the engine hood is too loose. 3. There may be a short circuit in the wiring, or the control key platinum may be aged or the spring may be too soft. 4. Issues with the two small buttons next to the front engine cover. 5. The sensor button on the driver's side door is broken. 6. The alarm system is malfunctioning. Solutions: 1. Open the engine hood; there is a black rubber door control trigger switch near the left headlight. Use double-sided tape to thicken the contact area between the switch and the hood, shorten the switch's travel distance, and bypass the hood switch without using it. 2. Use a car diagnostic device to read the fault codes and resolve the vehicle issues based on the fault codes. This requires a visit to a repair shop. 3. It is recommended to visit a service station for inspection. The TECH2 has a special function that displays the cause of the anti-theft alarm in a specific area. The service center's technicians will complete the repair based on the computer data.
