Lighting and Horns: Description and Operation

LIGHTING: LIGHTING SYSTEM: SYSTEM DIAGRAM






1. MANUAL LIGHT CONTROL SYSTEM

This system functions if the lights such as the headlights and taillights come on by manual operation of the light control switch.

(a) The main body ECU controls this system based on the signals listed below.





2. AUTOMATIC LIGHT CONTROL SYSTEM

When the light control switch is in the AUTO position, the automatic light control sensor detects ambient light, converts it into an electrical signal, and outputs it to the main body ECU. The main body ECU automatically turns the headlights and taillights on or off according to the signal.

(a) The main body ECU controls this system based on the signals listed below.





3. LIGHT AUTO TURN OFF SYSTEM

When the headlights and taillights are on through the operation of the automatic light control system or through the light control switch, if the ignition switch is turned off and all doors are closed, this system continues to illuminate the headlights and taillights for approximately 30 seconds, and then turns off the headlights and taillights.

However, if the ignition switch is turned off and all doors are locked, this system turns off the headlights and taillights immediately.

(a) The main body ECU controls this system based on the signals listed below.





4. DAYTIME RUNNING LIGHT SYSTEM

The daytime running light system is designed to automatically illuminate the headlights (dimmed HI beams), during the daytime to make the car more visible to other vehicle.

(a) The main body ECU controls this system.

The daytime running light system starts operating when all of the following conditions are met:





HINT
*: only for Canadian package models.

5. ILLUMINATED ENTRY SYSTEM

When a door is unlocked through a key or transmitter operation, or if a door is opened, the illuminated entry system turns on the interior light and the ignition key cylinder light.

(a) The main body ECU controls this system. The operation and condition of the illuminated entry system are described below.





6. POWER DISTRIBUTOR

(a) The power distributor (engine room J/B assembly) is installed in the engine room R/B.





(b) The HEAD relay and DRL relay are installed in the power distributor (engine room J/B assembly).

(c) When a short circuit occurs between the power distributor (engine room J/B assembly) and high beam headlight bulbs, a fail-safe function operates.

(d) When the fail-safe function operates, the power distributor stops the operation of the DRL relay.
