U1010 CONTROL UNIT (CAN)
DescriptionINFOID:0000000003759098
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.
CAN Communication Signal Chart, refer to LAN-22, "
CAN Communication Signal Chart".

HIGH FLASHER OPERATION
BCM detects the turn signal lamp circuit status by the current value.
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.
DTC Inspection Priority ChartINFOID:0000000003940048

System DescriptionINFOID:0000000003882700
Multi AV system means that the following systems are integrated.
AV control unit controls by transmitting/receiving data one by one with each unit (slave unit) that configures
them completely as a master unit by connecting between units that configure MULTI AV system with two AV
communication lines (H, L).
Two AV communication lines (H, L) adopt a twisted pair line that is resistant to noise.
AV control unit is connected by CAN communication, and it receives data signal from ECM, combination
meter. It computes and displays fuel economy information value with the obtained information. Transmitting/
receiving of data signal is performed by BCM. Also, it transmits the required signal of vehicle setting and
receives the response signal.
