Purpose
The lights-on reminder warning alarm notifies the driver that the TNS and headlights are not turned off.
Function
The instrument cluster receives the following vehicle condition signals via the CAN signal from the start stop unit and rear body control module (RBCM).
TNS switch ON signal from start stop unit (TNS and headlights illuminate)
Driver's front door latch switch ON signal from rear body control module (RBCM)
If the ignition is switched to OFF or ACC when all the above vehicle condition signals are received, the instrument cluster operates the lights-on reminder alarm.
The lights-on reminder warning alarm sound pattern is as shown in the figure.

Construction
The lights-on reminder warning alarm sounds using the buzzer built into the instrument cluster.
Operation
1. The instrument cluster receives (1) the TNS switch ON signal from the start stop unit and driver's front door latch switch ON signal from the rear body control module (RBCM).
2. When the ignition is switched to OFF or ACC while each signal is received, the instrument cluster turns on (2) the transistor.
3. When the transistor turns on, the ground circuit of the alarm is established and the alarm sounds (3).
