Check Door Switch

DIAGNOSIS PROCEDURE CHART

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 "PC application for Subaru Select Monitor".
  3. On the "System Selection Menu", select {Integ. unit mode}.
  4. Select the {Current Data Display & Save}.
  5. Check the input of the doors and rear gate latch switches to the body integrated unit when opening each door (front RH and LH, rear RH and LH, and rear gate).
 Is the input signal detected when opening the each door (front RH and LH, rear RH and LH, and rear gate)? The door and rear gate latch switch circuits are normal. If there is a door switch or rear gate latch switch where the input signal cannot be detected, 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.
  3. Disconnect the harness connector of the faulty door or rear gate latch switch.
  4. Measure the resistance between harness connector terminals.

Connector & terminal 
(i84) No. 19 - (R12) No. 1: (front door RH) 
(i84) No. 32 - (R9) No. 1: (front door LH) 
(i84) No. 6 - (R16) No. 1: (rear door RH) 
(i84) No. 20 - (R22) No. 1: (rear door LH) 
(i84) No. 33 - (D46) No. 3: (rear gate) 		 Is the resistance less than 10 Ω? Go to step 3  . Repair or replace the harness.
3 CHECK GROUND CIRCUIT OF DOOR SWITCH  .
  1. Disconnect the harness connector of the faulty door or rear gate latch switch.
  2. Measure the resistance of harness connector and chassis ground.

Connector & terminal 
(R12) No. 3 - Chassis ground: (front door RH) 
(R9) No. 3 - Chassis ground: (front door LH) 
(R16) No. 3 - Chassis ground: (rear door RH) 
(R22) No. 3 - Chassis ground: (rear door LH) 
(D46) No. 4 - Chassis ground: (rear gate) 		 Is the resistance less than 10 Ω? Go to step 4  . Repair or replace the harness.
4 CHECK DOOR SWITCH  .
  1. Disconnect the harness connector of the faulty door or rear gate latch switch.
  2. Measure the resistance between door switch and rear gate latch switch terminals.

Terminals 
No. 1 - No. 3: (except rear gate) 
No. 3 - No. 4: (rear gate) 		 Is the resistance 1 MΩ or more when the door switch is pushed and the rear gate is closed? Go to step 5  . Replace the door switch, or rear gate latch and actuator assembly.
5 CHECK DOOR SWITCH  .
Measure the resistance between door switch and rear gate latch switch terminals.
Terminals 
No. 1 - No. 3: (except rear gate) 
No. 3 - No. 4; (rear gate) 		 Is the resistance less than 1 Ω when door switch is released and the rear gate is opened? Check the body integrated unit. Refer to BASIC DIAGNOSTIC PROCEDURE . Replace the door switch, or rear gate latch and actuator assembly.
