Bonneville V6-3800 3.8L VIN L SFI (1995)
Lamp Out Indicator: Description and Operation
The lamp monitor system is made up of two main components: the Driver Information Center (DIC) (Oldsmobile and Pontiac) or the Lamp Monitor
Display (Buick) and the Adaptive Lamp Monitor Module. The Adaptive Lamp Monitor Module monitors each lighting circuit by looking at voltage
across internal resistors in each monitored lighting circuit. If the voltage drop across one of these resistors decreases by a certain percentage, the
Adaptive Lamp Monitor Module recognizes this as a lamp outage and communicates this information over the serial data line to the DIC (Oldsmobile
and Pontiac) or the Lamp Monitor Display (Buick). The DIC (Oldsmobile and Pontiac) then displays an outage and sounds a slow chime for 5 seconds.
The Lamp Monitor Display (Buick) flashes the corresponding Light Emitting Diode (LED) for approximately 10 seconds, then lights the LED indicating
a bulb outage.
The Adaptive Lamp Monitor Module is adaptive because it may be used in vehicles with various lighting configurations. This module recognizes and
adapts to a particular lighting configuration when the ignition switch is in "RUN" and the park lamps are turned on. This module must relearn the vehicle
lighting configuration if the battery is disconnected.
