Check Door Switch

STEP CHECK SHEET

Step	Check	Yes	No
1. CHECK INPUT FROM EACH DOOR SWITCH. Connect the Subaru Select Monitor to data link connector. Turn the ignition switch to ON. Select {body integrated module} from main menu. Select {Current Data Display & Save}. Check the door switch input to the body integrated unit when opening the each door (front RH and LH, rear RH and LH).	Is the input signal present when opening each door (front RH and LH, rear RH and LH)?	The door switch circuit is OK.	When the input signal cannot be detected in some door switch, Go to step 2.
2. CHECK DOOR SWITCH CIRCUIT. Turn the ignition switch to OFF. Disconnect the harness connector of body integrated unit. Disconnect the harness connector of faulty door switch. Measure the resistance between harness connector terminals. Connector & terminal (i84) No. 19 - (R12) No. 1: (front door LH) (i84) No. 32 - (R9) No. 1: (front door RH) (i84) No. 31 - (R22) No. 1: (rear door LH) (i84) No. 18 - (R16) No. 1: (rear door RH)	Is the resistance less than 10 Ω?	Go to step 3.	Repair the harness.
3. CHECK GROUND CIRCUIT OF DOOR SWITCH. Disconnect the harness connector of faulty door switch. Measure the resistance of harness connector and chassis ground. Connector & terminal (R9) No. 3 - Chassis ground: (front door LH) (R12) No. 3 - Chassis ground: (front door RH) (R22) No. 3 - Chassis ground: (rear door LH) (R16) No. 3 - Chassis ground: (rear door RH)	Is the resistance less than 10 Ω?	Go to step 4.	Repair the harness.
4. CHECK DOOR SWITCH. Disconnect the harness connector of faulty door switch. Measure the resistance between the door switch terminals. Terminals No. 1 - No. 3:	Is the resistance more than 1 MΩ when door switch is pushed?	Go to step 5.	Replace the door switch.
5. CHECK DOOR SWITCH. Measure the resistance between the door switch terminals. Terminals No. 1 - No. 3:	Is the resistance less than 1 Ω when door switch is released?	Check the body integrated unit. < Ref. to , BASIC DIAGNOSTIC PROCEDURE . >	Replace the door switch.
