U0300 CAN COMMUNICATION DATA
U0300 CAN COMMUNICATION DATA
Description
INFOID:0000000009019911
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 malfunction detection ability.
Many electronic control units are equipped onto a vehicle, and each control unit shares information and links
with other control units during operation (not independently). In CAN communication, control units are con-
nected 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.

DTC CONFIRMATION PROCEDURE
1.
PREPARATION BEFORE WORK
If another “DTC CONFIRMATION PROCEDURE” occurs just before, turn ignition switch OFF and wait for at
least 10 seconds, then perform the next test.
>> GO TO 2.
2.
CHECK DTC DETECTION
With CONSULT
1. Start the engine and wait for 5 seconds or more.
2. Check the DTC.
Is “U0300” detected?
YES

NO
>> INSPECTION END
Diagnosis Procedure
INFOID:0000000009019913
1.
CONTROL UNIT CHECK
Check the number of control units replaced before “U0300” is detected.
Is one control unit replaced?
YES
>> The specification of the control unit replaced may be incorrect. Check the part number and the
specification.
NO
>> GO TO 2.
2.
CONTROL UNIT CHECK
With CONSULT
1. Remove one of the control unit replaced.
2. Assemble the old control unit before replacement.
3. Turn ignition switch ON, and wait for 2 seconds or more.
4. Select “Self Diagnostic Results” in “TRANSMISSION”.
Is “U0300”detected?
YES
>> Turn OFF the ignition switch and check other control units in the same manner.
NO
>> The specification of the control unit removed may be incorrect. Check the part number and the
specification.

Description
INFOID:0000000009019920
TCM compares the calculated value stored in the flash ROM with the value stored in TCM. If the calculated
value does not agree with the stored value, TCM judges this as a malfunction.
