Auto light control operation
WARNING: This page is about a different car, the 2003 Nissan Pathfinder. However, it is still accessible from the selected car via links, so may be relevant.
While the headlamps are turned ON by "AUTO" operation, the exterior lamp battery saver is activated for 5 minutes when the ignition switch is turned from ON (or ACC) to OFF, and either LH or RH front door switch is opened.
The smart entrance control unit controls exterior lamp battery saver activation as follows:
- When the door switch signal changes from ON to OFF while the exterior lamp battery saver is activated, the operation is discontinued, and restarts and lasts for 45 seconds, then the headlamps will be turned off.
- When the door switch signal changes from OFF to ON while the exterior lamp battery saver is activated, the operation discontinued, restarts and lasts for 45 seconds, then the headlamps will be turned off.
- When the one of four door switch signals changes from OFF to ON while the exterior lamp battery saver is activated, the operation is discontinued, restarts and lasts for 5 minutes, then the headlamps will be turned off.
- When all the door switch ON signals are input while the exterior lamp battery saver is activated, the saver is discontinued and restarts and lasts for 45 seconds, then the headlamps will be turned off.
Exterior lamp battery saver control time can be changed using "WORK SUPPORT" mode in "HEADLAMP".
When the lighting switch is turned from OFF to 2ND after headlamps are turned to off by the exterior lamp battery saver control, ground is supplied
- to smart entrance control unit terminals 20 and 58 from lighting switch terminal 11, and then,
- to headlamp LH and RH relays terminal 2 from smart entrance control unit terminals 21 and 59,
- through smart entrance control unit terminals 22 and 60 and
- through lighting switch terminal 12.
Then headlamps illuminate again.
