Check Door Switch

DIAGNOSIS PROCEDURE

Step Check Yes No
1 CHECK INPUT FROM EACH DOOR SWITCH. 
  1. Prepare the Subaru Select Monitor kit.
  2. Turn the ignition switch to ON (engine OFF), and run the "Application for Subaru Select Monitor III".
  3. On the System Selection Menu, select the {Integ. unit mode}.
  4. Select the {Current Data Display & Save}.
  5. 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 detected when opening the 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. 
  1. Turn the ignition switch to OFF.
  2. Disconnect the harness connector of body integrated unit (i84).
  3. Disconnect the defective door switch harness connector (any of R9, R12, R16, R22).
  4. 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. 
  1. Disconnect the defective door switch harness connector (any of R9, R12, R16, R22).
  2. 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. 
  1. Disconnect the defective door switch harness connector (any of R9, R12, R16, R22).
  2. Measure the resistance between door switch terminals.

    Terminals 

    No. 1 - No. 3: 

 Is the resistance 1 MΩ or more when door switch is pushed? Go to step 5.  Replace the door switch.
5 CHECK DOOR SWITCH. 
Measure the resistance between 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.
