ADJUSTING GLASS BREAKAGE SENSOR ON TOYOTA SECURITY SYSTEMS (TVSS & TDSE)

Vehicles equipped with port and dealer installed Toyota security systems may experience an inoperative alarm or "false alarms" due to misadjustment of the glass breakage sensor.





The sensitivity of the glass breakage sensor may be adjusted lower or higher than recommended, causing the alarm to be inoperative or over-sensitive.

To correct this condition, readjust the glass breakage sensor to the recommended settings for each Toyota vehicle as indicated in this bulletin.

The sensitivity adjustment screw should be calibrated as follows:

1. Turn the click type adjusting screw counterclockwise until screw stops (do not force screw).

2. Use the sensitivity setting table for model and year that apply.
3. Turn adjustment screw clockwise counting the number of "CLICKS" as indicated in table.
