DIAGNOSTIC PROCEDURE

Step	Check	Yes	No
1 CHECK DTC. Turn the ignition switch to ON. Keep the Parking range for approx. 5 seconds. Read the DTC of body integrated unit using Subaru Select Monitor.	Is B1106 current malfunction?	Go to step 6 .	Go to step 2 .
2 CHECK DTC. Turn the ignition switch to OFF. Disconnect the shift lock solenoid connector. Connect the disconnected connectors. Turn the ignition switch to ON, then keep the Parking range for approx. 5 seconds. Read the DTC of body integrated unit using Subaru Select Monitor.	Is B1106 current malfunction?	Go to step 3 .	Go to step 7 .
3 CHECK HARNESS. Turn the ignition switch to OFF. Disconnect the shift lock solenoid connector. Using the tester, measure the resistance between terminals. Connector & terminal (B116) No. 4 - Chassis ground:	Is the resistance less than 10 Ω?	Go to step 4 .	Repair or replace the open circuit of harness.
4 CHECK SHIFT LOCK SOLENOID. Using a tester, measure the resistance between shift lock solenoid terminals. Connector & terminal (B116) No. 4 - No. 3:	Is the resistance less than 27 - 31 Ω?	Go to step 5 .	Replace the shift lock solenoid. Refer to DISASSEMBLY , Select Lever.
5 CHECK SHIFT LOCK SOLENOID. Connect the battery terminal to shift lock solenoid. Connector & terminal (B116) No. 3 - positive terminal: (B116) No. 4 - ground terminal:	Does the shift lock solenoid operate and then release the lock?	Go to step 6 .	Replace the shift lock solenoid. Refer to DISASSEMBLY , Select Lever.
6 CHECK HARNESS. Use a tester to measure the resistance between harness terminals. Connector & terminal (B116) No. 3 - (B281) No. 5: NOTE: If body integrated unit and shift lock connector are not disconnected, disconnect them first and then perform measurement.	Is the resistance less than 10 Ω?	Replace the body integrated unit. Refer to BODY INTEGRATED UNIT .	Repair or replace the open circuit of harness.
7 CHECK DTC. Depress the brake pedal at the parking range. Read the DTC of body integrated unit using Subaru Select Monitor.	Is B1106 current malfunction?	Go to step 8 .	Go to step 9 .
8 CHECK DTC. Turn the ignition switch to OFF. Disconnect the body integrated unit connector and shift lock connector. Connect the disconnected connectors. Turn the ignition switch to ON. Depress the brake pedal at the parking range. Read the DTC of body integrated unit using Subaru Select Monitor.	Is B1106 current malfunction?	Go to step 4 .	Go to step 9 .
9 CHECK CONNECTOR. Turn the ignition switch to OFF. Disconnect the body integrated unit connector and shift lock connector.	Is there poor contact of connector terminal?	Repair or replace the poor contact of terminal.	It is possible that temporary poor contact occurs.
