Auto Light System
AUTO LIGHT SYSTEMSystem Description
Automatically turns on/off the parking lamps and the headlamps in accordance with ambient light. Timing for when the lamps turn on/off can be selected using four modes.
OUTLINE
The auto light control system has an optical sensor inside it that detects outside brightness. When the lighting switch is in "AUTO" position, it automatically turns on/off the parking lamps and the headlamps in accordance with the ambient light. Sensitivity can be adjusted in four steps. For the details of the setting, Refer to "SETTING CHANGE FUNCTIONS".
Optical sensor, power is supplied
- from BCM (body control module) terminal 17
- to optical sensor terminal 1.
Optical sensor, ground is supplied
- from BCM (body control module) terminal 18
- to optical sensor terminal 3.
When ignition switch is turn to "ON" position, and
When outside brightness is darker than prescribed level, input is supplied
- to BCM (body control module) terminal 14
- from optical sensor terminal 2.
The headlamps will then illuminate. For a description of headlamp operation, Refer to "System Description".
COMBINATION SWITCH READING FUNCTION
Refer to "COMBINATION SWITCH READING FUNCTION". Body Control Module
EXTERIOR LAMP BATTERY SAVER CONTROL
When a lighting switch changes into the state of off of an ignition switch from the state of ACC or ON by 1st position, a function in case a lighting switch is except AUTO or OFF in the state of ignition carries out the timer operation of the output of headlamp, fog lamp, and tall lamp for 5 minutes, is not based on the input conditions of a combination switch after that, but is set to OFF.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-II.
SHUT OFF DELAY
When ignition switch is in the state of ON or ACC and a lighting switch is an AUTO position, after OFF and a door switch (a driver, passenger) serve as ON from the state of ON of headlamp in an ignition switch, a headlamp is turned on for 5 minutes, and headlamp, parking lamp, and fog lamp are set OFF after that.
When a door switch (a driver, passenger) is turned on from OFF during 45 seconds or a 5 minute timer operation, the present timer stops, newly turns on a headlamp for 5 minutes, and sets headlamp, parking lamp, and fog lamp to OFF after that.
When a door switch (a driver, passenger) is turned off from ON during 45 seconds or a 5 minute timer operation, the present timer stops, newly turns on a head lamp for 45 seconds, and sets a headlamp, parking lamp, and fog lamp to OFF after that.
When an ignition switch is turned off from ON during the above mentioned timer operation, the function, which stopped the timer and followed each lighting switch, is performed.
Shut off delay control mode can be changed by the function setting of CONSULT-II.
CAN Communication System Description
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability Many electronic control units are equipped onto a vehicle, and each control unit shares information and links with other control units during operation (not independent). In CAN communication, control units are connected with 2 communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
