1 Component Parts and Harness Connector Location Component Parts and Harness Connector Location NBEL0159 System Description SEL044W The headlamp operation is controlled by the lighting switch which is built into the combination switch and headlamp battery saver control unit. And the headlamp battery saver system is controlled by the headlamp battery saver control unit and smart entrance control unit. OUTLINE Power is supplied at all times NBEL0012S04 to headlamp LH relay terminals 2 and 3 through 15A fuse (No. 60, located in the fuse and fusible link box), and to headlamp RH relay terminals 2 and 3 through 15A fuse (No. 59, located in the fuse and fusible link box), and to headlamp battery saver control unit terminal 7 through 7.5A fuse [No. 24, located in the fuse block (J/B)]. When the ignition switch is in the ON or ART position, power is supplied to headlamp battery saver control unit terminal 1 through 10A fuse [No. 16, located in the fuse block (J/B)], and to headlamp battery saver control unit terminal 10, and to smart entrance control unit terminal 33 through 7.5A fuse [No. 11, located in the fuse block (J/B)] Ground is supplied to headlamp battery saver control unit terminals 4 and 11.

2 System Description (Cont d) When Ignition Switch is in ON or ART Position NBEL0012S0401 Ground is supplied to headlamp LH relay terminal 1 from headlamp battery saver control unit terminal 2 through headlamp battery saver control unit terminal 3, and through body grounds M4 and M66, and to headlamp RH relay terminal 1 from headlamp battery saver control unit terminal 8 through headlamp battery saver control unit terminal 9, and through body grounds M77 and M111. Headlamp relays (LH and RH) are then energized. When Ignition Switch is in OFF or ACC Position NBEL0012S0402 When lighting switch is in 2ND (or 1) position, ground is supplied to headlamp battery saver control unit terminals 5 and 13 from lighting switch terminal 11. And then, ground is also supplied to headlamp LH and RH relays terminal 1 from headlamp battery saver control unit. Headlamp relays (LH and RH) are then energized. LOW BEAM OPERION NBEL0012S01 When the lighting switch is turned to the 2ND position and placed in LOW ( B ) position, power is supplied from lighting switch terminal 10 to terminal 2 of the LH headlamp, and from lighting switch terminal 7 to terminal 2 of the RH headlamp. Terminal 3 of each headlamp supplies ground through body grounds E13 and E41. With power and ground supplied, the headlamp(s) will illuminate. HIGH BEAM OPERION/FLASH-TO-PASS OPERION NBEL0012S02 When the lighting switch is turned to the 2ND position and placed in HIGH ( A ) position or PASS ( C ) position, power is supplied from lighting switch terminal 6 to terminal 1 of the RH headlamp, and from lighting switch terminal 9 to terminal 1 of the LH headlamp, and to combination meter terminal 33 for the high beam indicator. Ground is supplied to terminal 19 of the combination meter through body grounds M77 and M111. Terminal 3 of each headlamp supplies ground through body grounds E13 and E41. With power and ground supplied, the high beams and the high beam indicator illuminate. ERY SAVER CONTROL NBEL0012S05 When the ignition switch is turned from ON (or ART) to OFF (or ACC) positions while headlamps illuminate, the RAP signal is supplied to terminal 10 of the headlamp battery saver control unit from smart entrance control unit terminal 5. After counting 45 seconds by the RAP signal from the smart entrance control unit to headlamp battery saver control unit, the ground supply to terminal 1 of the headlamp LH and RH relay from headlamp battery saver control unit terminals 2 and 8 is terminated. Then the headlamps are turned off. The headlamps are turned off when driver or passenger side door is opened even if 45 seconds have not passed after ignition switch is turned from ON (or ART) to OFF (or ACC) positions while headlamps are illuminated. When the lighting switch is turned from OFF to 2ND after headlamps are turned to off by the battery saver control, ground is supplied to headlamp battery saver control unit terminals 5 and 13 from lighting switch terminal 11, and to headlamp LH and RH relays terminal 1 from headlamp battery saver control unit terminals 2 and 8. Then headlamps illuminate again. EL-26
