Purpose
The auto light-Off system turns off the TNS or headlights automatically.
The front body control module (FBCM) performs auto light-Off system fail-safe..
Function
The auto light-Off system controls the front body control module (FBCM).
The front body control module (FBCM) controls the auto light-Off system based on the following signals and conditions:
IG power supply condition
TNS or headlight illumination condition
Light switch signal sent from start stop unit via CAN signal
If the front body control module (FBCM) detects that the ignition is switched off when the TNS and headlights are turned on, the TNS and headlights are turned on for a certain period of time and turned off after a certain period of time has elapsed.
A personalization feature has been adopted which can change the illumination time of the TNS or headlights. For details on the personalization features, refer to LIGHTING SYSTEM PERSONALIZATION.

Operation
If the front body control module (FBCM) detects that the ignition is switched off when the light switch is in the TNS/HEAD/AUTO position and the headlights are turned on, the TNS or headlights are turned on for 30 s*1 and turned off after 30 s.
If the front body control module (FBCM) receives the light switch signal from the start stop unit during the auto light-Off system operation, the headlight is controlled as follows:
Light switch switches to TNS/HEAD signal: Illuminates the light for 30 s after receiving the signal.
Light switch switches to OFF/AUTO signal: Turns off the light when receiving the signal.
