Tahoe 4WD V8-393 6.5L DSL Turbo VIN S (1995)
Audible Warning Device: Description and Operation
Key-In Warning Alarm
The Key-In Warning Alarm will sound if the following conditions are met simultaneously: The ignition key must be in the Ignition Switch with the
Ignition Switch in the ACC, LOCK or OFF position and the LH Front door must be open. The Audio Alarm Module incorporates a logic circuit which
senses whether or not the conditions are present for activating the alarm (ignition key in the Ignition Switch and the LH front door open). When the
ignition key is in the Ignition Switch and the LH front door is open, the Key-In Warning Buzzer Switch is closed as is the LH Door Jamb Switch. When
both of these switches are closed, the voltage being monitored at the Audio Alarm Module is low, thus indicating that the conditions are present for
activating the Key-In Warning Alarm. The Key-In Warning Alarm will stop sounding if the ignition key is removed from the Ignition Switch, the LH
front door is closed or the Ignition Switch is turned to the RUN position.
