Part 1
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.
Function
Wiper Control
Washer Control Coupled With Wiper
1. Under IGN2 = ON, wiper LOW relay is turned ON after T2 from Washer switch ON if washer switch is ON for T1 and wiper LOW relay is turned OFF after T3.
T1:0.06s~0.2s, T2:0.3s ±0.1s, T3:0.7s ±0.1s
2. Under IGN2 switch ON, wiper LOW relay is turned ON after T2 from Washer switch ON if washer switch is ON for at least T1, and wiper LOW relay is turned OFF after T3 from the moment that Washer switch is turned OFF.
T1:0.2s(MIN), T2:0.3s ±0.1s
T3:2.5s~3.8s(2 - 3 Turn)
3. Operation in Item (2) is performed if Washer switch is ON for at least T1 during WIPER operation with Wiper int switch. Operation in Item (1) is performed if Washer switch is ON for T6.
T1:0.2s(MIN) , T2:0.3s ±0.1s
T3:2.5s~3.8s(2 - 3 Turn), T4:T5 - 0.7s

Front Wiper Mist Function Wiper
1. Function Description
In case of IGN2 On (IGN2 ON), if turning on the Wiper Mist switch(Wiper Mist switch On), then Wiper is controlled, by switch on time. Mist operation does not work at Wiper Washer.
T1 : One Wiping, T2 : Mist One Time
2. Under IGN2 switch ON, Wiper LOW relay is turned ON immediately from Mist switch ON if Mist switch ON for more than T1, Wiper LOW relay is turned OFF after T2 from Mist switch OFF.
T1 : 0.7s(Min), T2 : 0.7s±0.1s
Variable Int Wiper
1. Under IGN2 switch ON & Wiper Int switch ON states, and wiper int volume value are acquired and intermittent time is calculated. then, wiper intermittent time is automatically converted.
T1 : 0.7 ± 0.1s, T2 : INT Time( 2.2 ± 0.2s ~ 10 ± 1s)
*1 ON : IGN2 = ON OFF: IGN2 = OFF
2. Wiper Control Precaution
(1) Variable int wiper
A. Wiper low relay time is 0.7s ±0.1s.
B. Intermittent time is from output ON to the next output ON.
C. Wiper low relay output is continued for remaining ON time if INT switch is turned OFF during output.
D. Intermittent time is restarted when IGN2 switch is ON and wiper Int switch is changed from OFF to ON.
E. Intermittent time is restarted when wiper int switch is ON and IGN2 switch is changed from OFF to ON
F. 2.5V is used when volume value is 2.5V or more.
