Description
Body control module (A) receives various input
switch signals controlling time and alarm functions
for wiper control, tail lamp auto cut, auto light
control, front fog lamp, rear fog lamp, IGN key hole
illumination, buzzer control, seat belt warning, key
operated warning, ESCL warning, defogger timer,
front deicer timer, power window timer, door
lock/unlock control, trunk release control.
Function
Wiper Control
1.Wiper Data Flow
2. Washer Interlocking Wiper
(1) Turn Wiper Enable Relay ON after T1 when turning
Washer switch ON at the status of IGN2 ON and if
the input of Washer switch is between 0.06 and
0.2sec, turn the output of Wiper Enable Relay OFF
after T3.But, ignore the input of Washer switch
occurred while Wiper Enable Relay is being
operated and accept it from the input of Washer
switch after operating Wiper Enable Relay.
