Check Door Lock Switch

Step	Check	Yes	No
1 CHECK DOOR LOCK SWITCH. Check the input signal from door lock switch to body integrated unit using Subaru Select Monitor. Prepare the Subaru Select Monitor kit. Turn the ignition switch to ON (engine OFF), and run the "Application for Subaru Select Monitor III". On the System Selection Menu, select the {Integ. unit mode}. Select the {Current Data Display & Save}. Check the input signal to body integrated unit by operating the door lock switch.	Is the normal input signal displayed when the door lock switch is moved to LOCK/UNLOCK?	The door lock switch is OK.	Go to step 2 .
2 CHECK DOOR LOCK SWITCH CIRCUIT. Disconnect the harness connector of body integrated unit (i84). Measure the resistance between the harness connector terminal and chassis ground when moving the door lock switch to LOCK. Connector & terminal (i84) No. 15 - Chassis ground:	Is the resistance less than 10 Ω?	Go to step 3 .	Go to step 4 .
3 CHECK DOOR LOCK SWITCH CIRCUIT. Measure the resistance between the harness connector terminal and chassis ground when the door lock switch is moved to UNLOCK. Connector & terminal (i84) No. 29 - Chassis ground:	Is the resistance less than 10 Ω?	The door lock switch is OK.	Go to step 4 .
4 CHECK DOOR LOCK SWITCH. Disconnect the door lock switch harness connector (D7 or D125). Measure the resistance between the door lock switch terminals when moving the door lock switch to LOCK. Connector & terminal Driver's side: (D7) No. 5 - No. 9: Passenger's side: (D125) No. 2 - No. 5:	Is the resistance less than 1 Ω?	Go to step 5 .	Replace the door lock switch.
5 CHECK DOOR LOCK SWITCH. Measure the resistance between the door lock switch terminals when moving the door lock switch to UNLOCK. Connector & terminal Driver's side: (D7) No. 5 - No. 8: Passenger's side: (D125) No. 4 - No. 5:	Is the resistance less than 1 Ω?	Check the harness for open circuits or shorts between the body integrated unit and the door lock switch.	Replace the door lock switch.
