How to resolve the 'Vehicle Previously Intruded' alert on Buick vehicles?
1 Answers
Buick vehicles displaying a 'previously intruded' alert may have the following scenarios and corresponding solutions: Scenario 1: Occupant pulled door handle after locking. If an occupant inside the vehicle pulls the interior door handle after the vehicle is locked, the anti-theft system may misinterpret this as an intrusion attempt. Upon starting the vehicle, the dashboard will display a 'vehicle previously intruded' alert. Solution: This type of anti-theft system alert is normal behavior and requires no special attention. Scenario 2: Anti-theft alarm system triggered. When the vehicle is locked, pulling the exterior door handle will activate the alarm system, and the event will be automatically recorded in the vehicle's computer. Upon entering and starting the vehicle, the dashboard will display a 'vehicle previously intruded' alert. Solution: After confirming no actual intrusion occurred, the driver can manually dismiss the alert on the dashboard. Scenario 3: Faulty anti-theft module. A malfunctioning anti-theft module can cause system errors, leading to false intrusion alerts. Technicians can use specialized automotive diagnostic equipment to read the module's data and determine if it's faulty. Solution: Replace the anti-theft module. For vehicles under warranty, replacement is free at authorized 4S shops. Out-of-warranty vehicles cost approximately 200-300 RMB at 4S shops or about 200 RMB at independent repair shops. Even if the dashboard alert disappears after driving, it's important to promptly diagnose the cause and clear any stored faults in the control unit to prevent future issues.
