Step	Check	Yes	No
1 CHECK SPORT SHIFT SWITCH. Move the select lever to SPORT mode. Shift and hold the select lever to up side. Read the "Up Switch" data of TCM using Subaru Select Monitor. < Ref. to READ CURRENT DATA , OPERATION, Subaru Select Monitor. >	Is ON displayed?	Go to step 2.	Go to step 3.
2 CHECK SPORT SHIFT SWITCH. Shift and hold the select lever to down side. Read the "Down Switch" data of TCM using Subaru Select Monitor.	Is ON displayed?	Go to the procedure "INSPECTION FOR SPORT SHIFT INDICATOR LIGHT". < Ref. to CHECK SPORT SHIFT INDICATOR , Diagnostic Procedure without Diagnostic Trouble Code (DTC). >	Go to step 12.
3 CHECK THE BODY INTEGRATED UNIT. Turn the ignition switch to ON. Shift and hold the select lever to up side. Read the "TIP UP SW" data of body integrated unit using Subaru Select Monitor. < Ref. to OPERATION , Subaru Select Monitor. >	Is ON displayed?	Go to step 4.	Go to step 5.
4 CHECK THE BODY INTEGRATED UNIT. Check DTC of body integrated unit. < Ref. to OPERATION , Subaru Select Monitor. >	Is DTC of CAN communication displayed?	Perform the diagnosis according to DTC.	Check the TCM.
5 CHECK SPORT SHIFT SWITCH GROUND CIRCUIT. Turn the ignition switch to OFF. Disconnect the connector from SPORT shift switch. Measure the resistance of harness between SPORT shift switch connector and chassis ground. Connector & terminal (B116) No. 6 - Chassis ground:	Is the resistance less than 1 Ω?	Go to step 6.	Repair the open circuit of harness between SPORT shift switch and chassis ground.
6 CHECK SPORT SHIFT SWITCH. Measure the resistance between SPORT shift switch terminals. Connector & terminal (B116) No. 6 - No. 7:	Is the resistance more than 1 MΩ?	Go to step 7.	Replace the guide plate assembly.
7 CHECK SPORT SHIFT SWITCH. Shift and hold the select lever to up side. Measure the resistance between SPORT shift switch terminals. Connector & terminal (B116) No. 6 - No. 7:	Is the resistance less than 1 Ω?	Go to step 8.	Replace the guide plate assembly.
8 CHECK HARNESS CONNECTOR BETWEEN BODY INTEGRATED UNIT AND SPORT SHIFT SWITCH. Disconnect the connector from body integrated unit. Measure the resistance of harness between body integrated unit connector and SPORT shift switch connector. Connector & terminal (B116) No. 7 - (B281) No. 15:	Is the resistance less than 1 Ω?	Go to step 9.	Repair the open circuit of harness between SPORT shift switch connector and TCM connector, or poor contact in connector.
9 CHECK HARNESS CONNECTOR BETWEEN TCM AND SPORT SHIFT SWITCH. Measure the resistance of harness between SPORT shift switch connector and chassis ground. Connector & terminal (B116) No. 7 - Chassis ground:	Is the resistance more than 1 MΩ?	Go to step 10.	Repair the short circuit of harness between SPORT shift switch connector and TCM connector.
10 CHECK INPUT SIGNAL TO BODY INTEGRATED UNIT. Connect ail connectors. Turn the ignition switch to ON (engine OFF). Check the signal voltage for body integrated unit. Connector & terminal (B281) No. 15 (+) - Chassis ground (-):	Is the voltage 1.5 - 8 V?	Go to step 11.	Replace the body integrated unit.
11 CHECK INPUT SIGNAL TO BODY INTEGRATED UNIT. Shift and hold the select lever to up side. Check the signal voltage for body integrated unit. Connector & terminal (B281) No. 15 (+) - Chassis ground (-):	Is the voltage less than 1 V?	Go to step 21.	Replace the body integrated unit.
12 CHECK THE BODY INTEGRATED UNIT. Turn the ignition switch to ON. Shift and hold the select lever to down side. Read the 'TIP DOWN SW" data of body integrated unit using Subaru Select Monitor. < Ref. to OPERATION , Subaru Select Monitor. >	Is ON displayed?	Go to step 13.	Go to step 14.
13 CHECK THE BODY INTEGRATED UNIT. Check DTC of body integrated unit.	Is DTC of CAN communication displayed?	Perform the diagnosis according to DTC.	Check the TCM.
14 CHECK SPORT SHIFT SWITCH GROUND CIRCUIT. Turn the ignition switch to OFF. Disconnect the connector from SPORT shift switch. Measure the resistance of harness between SPORT shift switch connector and chassis ground. Connector & terminal (B116) No. 10 (+) - Chassis ground:	Is the resistance less than 1 Ω?	Go to step 15.	Repair the open circuit of harness between SPORT shift switch and chassis ground.
15 CHECK SPORT SHIFT SWITCH. Measure the resistance between SPORT shift switch terminals. Connector & terminal (B116) No. 10 - No. 11:	Is the resistance more than 1 MΩ?	Go to step 16.	Replace the guide plate assembly.
16 CHECK SPORT SHIFT SWITCH. Shift and hold the select lever to down side. Measure the resistance between SPORT shift switch terminals. Connector & terminal (B116) No. 10 - No. 11:	Is the resistance less than 1 Ω?	Go to step 17.	Replace the guide plate assembly.
17 CHECK HARNESS CONNECTOR BETWEEN BODY INTEGRATED UNIT AND SPORT SHIFT SWITCH. Disconnect the connector from body integrated unit. Measure the resistance of harness between body integrated unit connector and SPORT shift switch connector. Connector & terminal (B116) No. 11 - (B281) No. 25:	Is the resistance less than 1 Ω?	Go to step 18.	Repair the open circuit of harness between SPORT shift switch connector and TCM connector, or poor contact in connector.
18 CHECK HARNESS CONNECTOR BETWEEN BODY INTEGRATED UNIT AND SPORT SHIFT SWITCH. Measure the resistance of harness between SPORT shift switch connector and chassis ground.
