U1010 CONTROL UNIT (CAN)
DescriptionINFOID:0000000001396718
CAN (Controller Area Network) is a serial communication line for real time applications. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Modern
vehicle is equipped with many electronic control unit, 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.

TURN SIGNAL LAMP CONTROL
BCM detects the turn signal lamp circuit status from the terminal voltage.
BCM increases the turn signal lamp blinking speed if the bulb or harness open is detected with the turn signal
lamp operating.
NOTE:
The blinking speed is normal while activating the hazard warning lamp.
LIGHT & RAIN SENSOR MALFUNCTION DETECTION FUNCTION
BCM controls the following items when LIGHT & RAIN sensor has a malfunction.
Auto Light Control
