DIAGNOSTIC PROCEDURE

Step	Check	Yes	No
1 CHECK INPUT SIGNAL FOR TCM. Turn the ignition switch to ON. Move the select lever to each range, and read the data of «P range», «R Range Signal», «N range» and «D Range Signal» using the Subaru Select Monitor.	Is display "OFF" for the range other than corresponding range?	Go to step 5 .	Go to step 2 .
2 CHECK HARNESS. Turn the ignition switch to OFF. Disconnect the TCM and transmission connectors. Measure the resistance between TCM connector and chassis ground. Connector & terminal (B54) No. 5 - Chassis ground: (B54) No. 18 - Chassis ground: (B54) No. 9 - Chassis ground: (B54) No. 22 - Chassis ground:	Is each resistance 1 MΩ or more?	Go to step 3 .	Repair the short circuit of body harness.
3 CHECK HARNESS. Disconnect the inhibitor switch connector. Measure the resistance between transmission connector and chassis ground. Connector & terminal (T3) No. 1 - Chassis ground: (T3) No. 2 - Chassis ground: (T3) No. 3 - Chassis ground: (T3) No. 4 - Chassis ground:	Is each resistance 1 MΩ or more?	Go to step 4 .	Repair the short circuit of transmission harness.
4 CHECK INHIBITOR SWITCH. Move the select lever to each range, and measure the resistance between inhibitor switch connector terminals. Connector & terminal (T7) No. 2 - (T7) No. 1: (T7) No. 5 - (T7) No. 1: (T7) No. 3 - (T7) No. 1: (T7) No. 4 - (T7) No. 1:	Is the resistance other than corresponding range 1 MΩ or more?	Go to step 5 .	Replace the inhibitor switch. Refer to INHIBITOR SWITCH .
5 CHECK FOR POOR CONTACT.	Is there poor contact between TCM, inhibitor switch, transmission ground?	Repair the poor contact.	Check the TCM.
