Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Alarm does not sound when in reverse. | No power to the alarm; faulty wiring; blown fuse in vehicle's reverse circuit; alarm malfunction. | Check electrical connections for tightness and corrosion. Verify power supply to the alarm using a multimeter. Inspect vehicle's fuse box for a blown fuse related to reverse lights. If all checks fail, the alarm unit may be faulty and require replacement. |
| Alarm sounds intermittently. | Loose or corroded electrical connections; intermittent power supply. | Inspect all wiring and connections for looseness or signs of corrosion. Ensure the mounting is secure to prevent vibration-induced disconnections. |
| Sound is muffled or too quiet. | Obstruction in front of the speaker; improper mounting location. | Clear any debris from the speaker grille. Ensure the alarm is mounted in an open area, not obstructed by vehicle components or cargo, to allow sound to propagate effectively. |
