License Plate Lamp: Description and Operation

PARKING, LICENSE PLATE AND TAIL LAMPS

System Description

The parking, license side marker and tail lamps operation are controlled by the lighting switch which is built into the spiral cable and BCM. The battery saver system is controlled by the headlamp battery saver control unit and BCM.

Power is supplied at all times
- to tail lamp relay terminals 2 and 6
- through 15 A fuse [No. 54, located in the fuse, fusible link and relay block (J/B)], and
- to headlamp battery saver control unit terminal 7
- through 10 A fuse [No. 6, located in the fuse block (J/B) No. 1].

When ignition switch is in ON or START position, power is supplied
- to headlamp battery saver control unit terminal 1
- through 10 A fuse [No. 1, located in the fuse block (J/B) No. 1].

Ground is supplied
- to headlamp battery saver control unit terminals 4 and 11
- through body grounds M25 and M115.

LIGHTING OPERATION BY LIGHTING SWITCH
When lighting switch is in 1ST (or 2ND) position, ground is supplied
- to tail lamp relay terminal 1 from headlamp battery saver control unit terminals 6 and 14
- through headlamp battery saver control unit terminals 5 and 13
- through lighting switch terminals 11 and 5
- through body grounds M25 and M115.

Tail lamp relay is then energized and the parking, license, side marker and tail lamps illuminate.

BATTERY SAVER CONTROL
When the ignition switch is turned from ON (or START) to OFF (or ACC) positions while parking, license, side marker and tail lamps are illuminated, the RAP signal is supplied to terminal 10 of headlamp battery saver control unit terminal from BCM terminal 135.

After counting 45 seconds by the RAP signal from the BCM to headlamp battery saver control unit, the ground supply to terminal 1 of the tail lamp relay from headlamp battery saver control unit terminals 6 and 14 is terminated.

Then the parking, license, side marker and tail lamps are turned off.

The parking, license, side marker and tail lamps are turned off when driver or passenger side door is opened even if 45 seconds have not passed after the ignition switch is turned from ON (or START) to OFF (or ACC) positions while the parking, license, side marker and tail lamps are illuminated.

When the lighting switch is turned from OFF to 1ST (or 2ND) after the parking, license, side marker and tail lamps are turned off by the headlamp battery saver control, ground is supplied.
- to headlamp battery saver control unit terminals 5 and 13 from lighting switch terminal 11, and
- to tail lamp relay terminal 1 from headlamp battery saver control unit terminals 6 and 14.

Then the parking, license, side marker and tail lamps illuminate again.
