Step Check Yes No
1CHECK THE BODY INTEGRATED UNIT.
Check DTC of body integrated unit.
Is DTC of CAN communication
displayed?
Pe r for m t h e d ia g -
nosis according to
DTC.
Go to step 2.
2CHECK TCM.
Check DTC of TCM.
Is DTC of CAN communication
displayed?
Pe r for m t h e d ia g -
nosis according to
DTC.
Go to step 3.
3CHECK BUZZER STOP.
Disconnect the connector (B54).
Does the buzzer stop? Replace the TCM.
Tr a n s m i s s i o n C o n -

Go to step 4.
4CHECK THE BODY INTEGRATED UNIT.
1) Turn the ignition switch to OFF.
2) Connect the Subaru Select Monitor to data
link connector.
3) Turn the ignition switch to ON. (Engine
OFF)
4) Turn the Subaru Select Monitor switch to
ON.
5) Read the data of SPORT shift buzzer using
Subaru Select Monitor.
Is the SPORT shift buzzer dis-
play “ON”?
Replace the body
integrated unit.
