Downloaded from www.Manualslib.com manuals search engine 10B-3 Body Electrical Control System:
When “B” mode is selected and the door is locked using keyless entry transmitter or door request switch, the theft
deterrent light (1) flashes at 0.1 second interval for 20 seconds and the security alarm system is set to the stand-by
mode (2). Once it is set to the stand-by mode, the theft deterrent light blinks at 2 second intervals.
When the system is set to stand-by mode and the door is unlocked by some way other than using keyless entry
transmitter or door request switch and opened or cut off BCM power supply voltage temporarily, the alarm devices
operate according to the selected mode as described above.
The alarm stops under either of the following conditions.
• Ignition switch is turned ON
• A certain time has elapsed since the alarm started
For selection of the mode of the security alarm system, refer to “Security Alarm Mode Selection Procedure (If
Equipped)”.
