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.

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.
