U1000 CAN COMM CIRCUIT
COMPONENT DIAGNOSIS
U1000 CAN COMM CIRCUIT
Description
INFOID:0000000005260036
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-53, "CAN Communication Signal Chart"

Diagnosis Procedure
INFOID:0000000005260038
1.
PERFORM SELF DIAGNOSTIC
1. Turn ignition switch ON and wait for 2 second or more.
2. Check “Self Diagnostic Result”.
Is “CAN COMM CIRCUIT” displayed?
YES
>> Refer to
