Check Door Switch
DOOR SWITCH CHECKING PROCEDURE CHART
| Step |
Check |
Yes |
No |
1 CHECK INPUT FROM EACH DOOR SWITCH.
- Connect the Subaru Select Monitor to the data link connector.
- Turn the ignition switch to ON.
- Select {Integ. unit} from main menu.
- Select the {Current Data Display & Save}.
- 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.
- Turn the ignition switch to OFF.
- Disconnect the harness connector of body integrated unit.
- Disconnect the harness connector of faulty door switch.
- 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.
- Disconnect the harness connector of faulty door switch.
- Measure the resistance of harness connector and chassis ground.
Connector S 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.
- Disconnect the harness connector of faulty door switch.
- Measure the resistance between door switch terminals.
Terminals
No. 1 - No. 3:
|
Is the resistance more than 1 MΩ 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
