You can pull on each door when the alarm is on as well. The other common trigger would be the hood switch. Check its adjustment. Here is more information:
If the car alarm on your 2002 Ford Explorer keeps going off unexpectedly, there could be several potential causes for this issue:
Faulty or low battery in the key fob: A weak or malfunctioning battery in the key fob can trigger false alarms. Try replacing the battery in your key fob and see if the problem persists.
Door, hood, or trunk sensors: The alarm system includes sensors that detect if any of the doors, hood, or trunk are opened or tampered with. A faulty sensor can trigger the alarm. Inspect these sensors to ensure they are clean, properly aligned, and functioning correctly. Also, check if the door, hood, or trunk are fully closed and latched securely.
Faulty or misaligned door, hood, or trunk switches: The alarm system relies on switches located on the doors, hood, and trunk to detect their status. If any of these switches are misaligned or faulty, they may send incorrect signals to the alarm system, triggering false alarms. Inspect and adjust or replace these switches if necessary.
Malfunctioning alarm module: The alarm module itself could be malfunctioning, leading to false alarms. A diagnostic scan tool can help identify any error codes or issues with the alarm module. If necessary, a professional mechanic can further diagnose and replace the module if needed.
Wiring or electrical issues: Faulty wiring or electrical connections can cause false alarms. Inspect the wiring connections related to the alarm system for any damage, loose connections, or corrosion. If any issues are found, they should be repaired or replaced as necessary.
Environmental factors: Environmental factors such as strong vibrations, electromagnetic interference, or sudden changes in temperature can also trigger false alarms. However, these factors are typically less common causes compared to the issues mentioned above.
