Description

Body control module receives various input switch signals controlling time and alarm functions for the intermittent wiper timer, washer timer, rear defogger timer, seat belts warning, central door lock, ignition key reminder, power window, door warning, tail lamp, crash door unlock, ignition key hole illumination, rear fog lamp control and keyless entry & burglar alarm.
BCM, SJB(Smart Junction Box) and CLU(Instrument Cluster) are connected by CAN line.
The nearest module with input switch or actuator receives the input data to reduce the wiring and then send input data to the others which need them via CAN lines.
In case of sending output, it is used to CAN communication, not wiring.
SJB can also control relays and IPS.
So Each module allots the current data and actuation data.

4. | Multi-function wiring description

Function Description

1. | Head Lamp Low Control In IGN terminal State (IGN ON), if turn on the Head Lamp LOW switch(Head Lamp Low switch ON), Head Lamp LOW outputs are turned on (Head Lamp Low ON). When Tail lamp Off and headlamp Off conditions are satisfied at the same time, Head Lamp LOW and Tail LAMP turned off simultaneous immediately.

2. | Head Lamp High Control In IGN terminal State(IGN ON) and Head Lamp Low switch On(Head Lamp Low switch ON), if turn on the Head Lamp High switch(Head Lamp High switch ON), Head Lamp High Outputs are turned on (Head Lamp High ON).

3. | Passing Control In IGN terminal State(IGN ON), If Head Lamp Passing switch Input(Head Lamp High switch ON & Head Lamp Low control OFF) is detected then Head Lamp High Output(Head Lamp High ON) are turned on and Head Lamp Low Output(Head Lamp Low ON) at the same time.

4. | Canada DRL

A. | If alternator level is high(ALT L=On), BCM activates Canada DRL functionality and turns on the Head lamp high (CANADA DRL=On).

B. | Deactivation if:

(1) | Head lamp low On request by Head lamp switch or auto light head lamp Low control or

(2) | Head high On request by passing switch or

(3) | Parking brake switch On

5. | Escort Function After user generates the call of head lamp low light(Head Lamp Low switch On), if switch off ignition(IGN Off and START Off), and then keep Head Lamp Low Output On (Head Lamp Low ON)state during 20min. And after open and close driver side door(Driver door switch ON -> Driver door switch Off), user will have consequently lighting of head lamp low(Head Lamp Low ON) during only 30sec.
During active “Escort Function”, if receive Lock request 2 times (2 LOCK) or cancel the lighting request of head lamp low (Head Lamp Low switch Off & Auto Light switch Off), this function is released.
Lock request counting for 2 times (2 LOCK) is each follow cases:

(1) | RKE CMD == Lock

(2) | SMK RKE CMD == Lock

(3) | Passive Access Lock== Lock If open the Driver door(Driver door switch ON) or close(Driver door switch Off), former lock counter is cleared, and start new 2 times lock counting.

6. | Head Lamp Welcome Function "Multifunction switch head lamp or auto light position and lock stated, if remote unlock, and then keep head lamp output on state during 15second.Lighting state, if remote lock and unlock, immediately light turn off."

- | While escort function is activated, Tail lamp is keeping the turn on state and does not go to Auto cut and after finish escort state and user removes key, it can go Auto cut mode.

- | While the “Escort Function” is activated by ‘Head Lamp Low Switch’, if change from ‘Head Lamp Low Switch’ to ‘Lamp Auto Switch’, “Escort Function” is deactivated, because Lamp Auto mode is ‘Lamp Off’ condition.

- | While the “Escort Function” is activated by ‘Lamp Auto Switch’, if change from ‘Lamp Auto Switch’ to ‘Head Lamp Low Switch’, “Escort Function” is keeping the activation state, because of ‘Head Lamp On’ condition.

- | After IGN terminal off 20 minute timers is started, but as soon as door is opened and closed then 30sec timer is engaged.

Auto Light Control

1. | Overview Description This function describes the following features.

A. | Input detection by Auto Light Sensor.

B. | Generate Auto Light Out Status data.

C. | Send Auto Light Out Status.

D. | Tail Lamp Control by Auto light Mode.

E. | Head Lamp Low Control by Auto light Mode.

F. | AV Tail Control by Auto Light sensor level. Auto Light Mode State Diagram is based on Auto Light Sensor's level. Power condition of Auto Light Action.

G. | When ACC, IGN, START terminal states, Auto Light Sensor operates.

Auto Light Control Function In/out

1. | Auto Light Control Function Block Diagram

2. | Function Description In ACC, IGN, START terminal states, monitoring of the auto light sensor supply’s range (Auto Light Power) is performed and a failure is raises up (Auto Light failure) when the supply’s voltage is out of range(outside of range [4V:6V]).
If Auto Light failure occurs and as long as this error is present, the tailLamp and head lamp low must be turned on regardless of the sunlight level provided by the sensor.
When physical Auto Light sensor failure occurs the Lamps are turned on, because a zero voltage level is provided by the sensor when internal failure is present.
This is designed to prevent any head lamp cut off when the failure occurs during the night.
AV Tail Output Control is started In ACC, IGN,START regardless of MF switch Auto Light switch. CAN signal AV Tail is set/reset at the same time as AVTail.
