CHECK SYMPTOM
1.
Fill in described symptoms on the column “Symptom” in the check sheet.
2.
Connect all connectors, and then make sure that the symptom is reproduced.
OK or NG
OK
>> GO TO 14.
NG
>> Refer to
LAN-15, "Example of Filling in Check Sheet When Initial Conditions Are Not Reproduced"
.

UNIT REPRODUCIBILITY INSPECTION
Perform the following procedure for each unit, and then perform reproducibility test.
1.
Turn ignition switch OFF.
2.
Disconnect the battery cable from the negative terminal.
3.
Disconnect the unit connector.
4.
Connect the battery cable to the negative terminal.
5.
Make sure that the symptom filled in the “Symptom” of the check sheet is reproduced. (Do not confuse it
with the symptom related to removed unit.)
6.
Make sure that the same symptom is reproduced.

System Description
UKS003CT
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.
