Toyota Vehicle Intrusion Protection System
THEFT DETERRENT: TOYOTA VEHICLE INTRUSION PROTECTION SYSTEM:
SYSTEM DESCRIPTION
1. OUTLINE OF TOYOTA VEHICLE INTRUSION PROTECTION SYSTEM
HINT:
- The vehicle intrusion protection system has 2 modes: 1) active arming mode, which is the default mode, and 2) passive mode, witch can be turned ON/OFF (See CHANGING METHOD OF PASSIVE MODE).
- Toyota Vehicle Intrusion Protection System is referred to as TVIP in the troubleshooting section.
(a) When the system detects a vehicle intrusion, the system will sound the horns and flash the lights to alert the people around the vehicle to the intrusion.
HINT: Each mode (active and passive) has 4 states: disarmed state, arming preparation state, armed state, and alarm sounding state.
(1) Disarmed state:
- The user is near the vehicle.
- The alarm function does not operate.
- The theft deterrent function does not operate.
(2) Arming preparation state:
- Time from when the user locks the doors to when the use leaves the vehicle.
- Time for transferring to the armed state.
- The theft deterrent function does not operate.
(3) Armed state:
- The user leaves the vehicle completely.
- The theft deterrent function operates.
(4) Alarm sounding state:
While in the armed state, if a vehicle intrusion is detected, the system enters the alarm sounding state and the alarm function is activated.
Refer to the table for the alarming method and time:
HINT: In the alarm sounding state, when either of the front doors is unlocked and no key is inserted in the ignition key cylinder, a forced door lock signal is output.
2. ACTIVE ARMING MODE
HINT:
- Active arming mode starts the alarm control immediately after the doors are locked.
- This system activates as described in the diagram below when one of items for each condition is met.
(a) Active arming mode
3. PASSIVE ARMING MODE
HINT:
- Passive arming mode starts the alarm control after the key is out of the actuation area and doors are closed.
- Passive arming mode can be switched ON/OFF by the specified method.
- The alarm is initially set (when shipped from factory) to active arming mode (not passive arming mode).
- During passive arming mode, the theft deterrent system goes into the armed state even if the doors are not locked.
- Detecting that the doors are unlocked does not set off the alarm during passive arming mode.
- A forced door lock signal is not output during passive arming mode (see FORCED DOOR LOCK CONTROL).
- Although the theft deterrent system detects that the doors are opened during passive arming mode, the alarm will not go off immediately because an entry delay time is set.
- This system activates as described in the diagram below when one of items for each condition is met.
(a) Passive arming mode
HINT:
- *1: Disarmed state 1 is the normal disarmed state.
- *2: Disarmed state 2 is set from either the disarmed state 1 or the arming preparation state.
(b) Comparison with state of passive mode and state of active mode:
HINT: If closing all doors and lock them with a key or wireless operation in the passive mode, the system functions in active mode. If the state is charged into the disarmed state, the system returns to the passive mode.
4. ENTRY DELAY FUNCTION
(a) In the armed state, if either closed door is opened, the entry delay time will start.
If the transferring condition (Armed state -> Disarmed state) is satisfied during this entry delay time, the system will transfer to the disarmed state. However if the condition is not satisfied, the system will judge it to be an intrusion, and then the system will transfer to the alarm sounding state.
HINT: The entry delay time can be selected among 0, 14, 30 seconds by the customizing function.
5. CHANGING METHOD OF PASSIVE MODE (ON OR OFF)
(a) Procedure for changing of passive mode (ON or OFF)
HINT:
- Initial mode is PASSIVE MODE OFF.
- If there is a different signal in the middle of changing, it is invalid.
- * Entry delay time
6. SECURITY INDICATOR OUTPUT
HINT: Blinking frequency:
0.2 seconds (ON)
1.8 seconds (OFF)
7. FORCED DOOR LOCK CONTROL
(a) The forced door lock control prevents the vehicle from being tampered with. Immediately after a door is unlocked (alarm starts), the door is forced to lock by a forced door lock signal.
(1) Conditions that force the doors to lock:
When the key is not in the ignition key cylinder and both of the following conditions are met.
- The theft deterrent system is in the alarm sounding state of active arming mode.
- Any of the front door is unlocked.
- Since the previous forced door lock, 0.38 seconds or more have elapsed.
8. GLASS BREAKAGE SENSOR
(a) If the glass breakage sensor detects the glass is broken (1st time), the sensor will issue an alarm for 20 seconds (pre-alarming). If the glass breakage sensor detects the glass is broken further more (2nd time), the sensor will issue an alarm for 60 seconds.
(b) The sensitivity of the glass breakage sensor can be adjusted by the volume switch in the glass breakage sensor ECU.
HINT: The glass breakage sensor may issue a false alarm if the sensor's sensitivity is set too high.
