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 security control module harness connector terminal and chassis ground.
Connector & terminal 
Front and rear door: 
(B93) No. 5 (+) - Chassis ground (-): 
Rear gate or trunk lid: 
(B93) No. 4 (+) - 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 security control module harness connector terminal and chassis ground.
Connector & terminal 
Front and rear door: 
(B93) No. 5 (+) - Chassis ground (-): 
Rear gate or trunk lid: 
(B93) No. 4 (+) - Chassis ground (-): 
Does the measured value exceed the 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: 
No. 1 - No. 2: 
Is the measured value more than 1 MΩ when door switch is pushed? 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 1Ω when door switch is released? Check the harness for open circuits and shorts between the security control module and door switch. Replace the door switch.
