DTC CONFIRMATION PROCEDURE
1.PREPARATION BEFORE WORK
If another “DTC CONFIRMATION PROC EDURE” 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 >> Go to TM-295, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis ProcedureINFOID:0000000009464247
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 replac ed 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 remov ed may be incorrect. Check the part number and the
specification.

U1000 CAN COMM CIRCUIT
U1000 CAN COMM CIRCUIT
DescriptionINFOID:0000000009464248
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 vehi cle, 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 li ne) allowing a high rate of information transmission
with less wiring. Each control unit transmits/recei ves data but selectively reads required data only.
