RS3OOO TVIP PROGRAMMING CHANGES
FOR GBS
Models:
All Models
April 23, 1999
Introduction
Starting with 1999 MY, the programming in the RS3000 ECU for the Glass Breakage Sensor (GBS) to trigger the alarm has been changed to improve the Toyota Vehicle Intrusion Protection (TVIP) system's theft warning feature when glass breakage or impact to the glass is detected.
Previous operation of GBS (for 1998 MY and prior):
^ Upon (first) detection of breakage of the vehicle's glass, the GBS will sound the security system for 5 seconds (3 horn honks).
^ If there is a second detection of glass breakage, within 5 seconds of the first detection, the security system will sound for the full duration of 59 seconds.
Improved operation of GBS (from 1999 MY):
^ Upon (first) detection of breakage of the vehicle's glass, the GBS will sound the security system for 20 seconds.
^ If there is a second detection of glass breakage, the security system will sound for the full duration of 59 seconds, regardless of time between the first and second detections.
^ After the first detection, any subsequent detection will trigger the alarm for the full duration of 59 seconds as long as the security system is armed. The GBS trigger cycle will reset once the security system is disarmed and then rearmed.
This improvement is intended to enhance the previous trigger cycle of the security system and ward off an intruder.
The color of the previous (1998 MY and prior) R53000 ECU was black. The new R53000 ECU color is gray.

Repair Procedure
When performing the RS3OOO System Test, check the Glass Breakage Sensor sensitivity as follows:
1. Press and release the Remote Control's top button to arm the system.
2. Wait two seconds.
3. With the tip of the ignition key (or striker tool), softly tap the center of the driver's door window glass.
^ If the system is triggered (horn sounds for 20 seconds), the sensitivity must be adjusted. Turn the Glass Breakage Sensor ECU's adjustment screw counterclockwise one notch, and repeat this step again.
4. If the system is not triggered, repeat the glass tapping with moderate force.
^ The system should trigger when the glass is tapped with moderate force. If it is not triggered, turn the Glass Breakage Sensor ECU's adjustment screw clockwise one notch, and repeat this step again.
CAUTION:
Use caution when performing the step above. Do not tap the window glass with too much force, or the glass may crack or break. Use extra caution when the temperature is extremely cold.
NOTE:
The Owner's Guide included in the RS3OOO Base Kit is changed to reflect the (GBS logic) improvement. There is no change to the GBS ECU itself.
