CAN Communication System Description
AIS004UQ
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, 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.

Test item
Description
RETAINED PWR
This test is able to supply RAP signal (power) from BCM to power window system and
power sunroof system. Those systems can be operated when turning on “RETAINED
PWR” on CONSULT-II screen even if the ignition switch is turned OFF.
NOTE:
During this test, CONSULT-II can be operated with ignition switch in “OFF”
position.“RETAINED PWR” should be turned “ON” or “OFF” on CONLUST-II
screen when ignition switch in ON. Then turn ignition switch OFF for checking
retained power operation. CONSULT-II might be stuck if “RETAINED PWR” is
turned to “ON” or “OFF” on CONSULT-II screen when ignition switch is OFF.
