Step	Check	Yes	No
1 CHECK CURRENT DATA. Display the following items using Subaru Select Monitor. «Driver's door SW input» «P-door SW input» «Rear right door SW input» «Rear left door SW input» «R Gate SW input» NOTE: For detailed operation procedures, refer to "Application help".	Does the display switch between OFF ↔ ON when each door or trunk lid is opened/closed?	The door switch or the trunk lid latch switch is normal.	Go to step 2.
2 CHECK HARNESS. Disconnect the connector of body integrated unit. Disconnect the connector of the door switch or the trunk lid latch switch that the display does not change. Check the harness between body integrated unit and defective switch. Connector & terminal Front door LH (i84) No. 14 - (R9) No. 1: Front door RH (i84) No. 13 - (R12) No. 1: Rear door LH (i84) No. 24 - (R22) No. 1: Rear door RH (i84) No. 25 - (R16) No. 1: Trunk lid (i84) No. 33 - (R186) No. 3:	Is harness normal?	Go to step 3.	Repair or replace the harness.
3 CHECK HARNESS. Measure the resistance between the faulty switch connector and chassis ground. Connector & terminal Front door LH (R9) No. 3 - Chassis ground: Front door RH (R12) No. 3 - Chassis ground: Rear door LH (R22) No. 3 - Chassis ground: Rear door RH (R16) No. 3 - Chassis ground: Trunk lid (R186) No. 2 - Chassis ground:	Is the resistance less than 10 Ω?	Go to step 4.	Repair or replace the harness.
4 CHECK DOOR SWITCH. Measure the resistance between faulty switch terminals. Terminals Front LH door switch No. 1 - No. 3: Front RH door switch No. 1 - No. 3: Rear LH door switch No. 1 - No. 3: Rear RH door switch No. 1 - No. 3: Trunk lid latch switch No. 3 - No. 2:	Is the resistance 1 MΩ or more when the door switch is pushed and the trunk lid is closed?
