DIAGNOSIS PROCEDURE

Step	Check	Yes	No
1 CHECK INPUT SIGNAL OF BODY INTEGRATED UNIT USING SUBARU SELECT MONITOR. Turn the ignition switch to OFF. Connect the Subaru Select Monitor to data link connector. Turn the ignition switch and Subaru Select Monitor to ON. Depress the brake pedal. Read the input signal of stop light switch from Subaru Select Monitor. < Refer to OPERATION , Subaru Select Monitor. >	Is "ON" displayed?	Go to step 2.	Go to step 3.
2 CHECK DTC OF BODY INTEGRATED UNIT. Check DTC of the body integrated unit. < Refer to OPERATION , Read Diagnostic Trouble Code (DTC)\. >	Is DTC (B0106) displayed?	Repair or replace it according to the DTC.	Go to step 6.
3 CHECK STOP LIGHT SWITCH. Depress the brake pedal.	Does the stop light illuminate?	Go to step 4.	Check the stop light system.
4 CHECK HARNESS BETWEEN STOP LIGHT SWITCH AND BODY INTEGRATED UNIT. Turn the ignition switch to OFF. Disconnect the connectors of body integrated unit and stop light switch. Measure the resistance of harness between stop light switch and body integrated unit. Connector & terminal (B65) No. 3 - (B281) No. 23:	Is the resistance more than 1 MΩ?	Repair the open circuit of harness between the body integrated unit and stop light switch.	Go to step 5.
5 CHECK HARNESS BETWEEN STOP LIGHT SWITCH AND BODY INTEGRATED UNIT. Measure the resistance of harness between stop light switch and chassis ground. Connector & terminal (B65) No. 3 - Chassis ground:	Is the resistance less than 1 Ω?	Repair the short circuit of harness between the body integrated unit and stop light switch.	Go to step 7.
6 CHECK SHIFT LOCK SOLENOID. Disconnect the connector of shift lock solenoid. Connect the battery to connector terminal of shift lock solenoid, and operate the solenoid. Terminals No. 3 (+) - No. 4 (-):	Is the shift lock solenoid operating properly?	Go to step 7.	Replace the shift lock solenoid.
7 CHECK SHIFT LOCK OPERATION. Connect all the connectors. Shift the select lever to "P" range. Shift the select lever from "P" range to "R" range.	Can the select lever shift from "P" range to "R" range?	Check the body integrated unit.	A temporary poor contact of connector or harness may be the cause.
