Check Door Switch

WARNING: This page is about a different car, the 2005 Subaru Baja. However, it is still accessible from the selected car via links, so may be relevant.
DOOR SWITCH

Step Check Yes No
1 CHECK DOOR SWITCH CIRCUIT. 
Measure the voltage between the keyless entry control module harness connector terminal and chassis ground.
Connector & terminal 
Front and rear side door: 
(B176) No. 10 (+) - Chassis ground (-): 
Rear gate or trunk lid: 
(B176) No. 9 (+) - Chassis ground (-): 
Is the measured value less than 1.5 V when each door, rear gate or trunk lid is opened? Go to step 2.  Go to step 3. 
2 CHECK DOOR SWITCH CIRCUIT. 
Measure the voltage between the keyless entry control module harness connector terminal and chassis ground.
Connector & terminal 
Front and rear side door: 
(B176) No. 10 (+) - Chassis ground (-): 
Rear gate or trunk lid: 
(B176) No. 9 (+) - Chassis ground (-): 
Does the measured value more than 10 V when all doors and rear gate or trunk lid is closed? The door switch is OK. Go to step 3. 
3 CHECK DOOR SWITCH. 
  1. Disconnect the door switch harness connector.
  2. Measure the resistance between the door switch terminals.

Terminal 
Door switch No. 1 - No. 3: 
Rear gate latch switch or trunk room 
light switch No. 1 - No. 2: 
Is the measured value more than 1 MΩ when the door switch is depressed? Go to step 4.  Replace the door switch.
4 CHECK DOOR SWITCH. 
Measure the resistance between the door switch terminals.
Terminal 
Door switch No. 1 - No. 3: 
Rear gate latch switch or trunk room 
light switch No. 1 - No. 2: 
Is the measured value less than 1 Ω when the door switch is released? Check the harness for open circuits and shorts between the integrated module and door switch. Replace the door switch.
