4. CHECK DOOR SWITCH
Step Check Yes No
1 CHECK INPUT FROM EACH DOOR SWITCH
1) Connect the Subaru Select Monitor to data
link connector.
2) Turn the ignition switch to ON.
3) Select {Integ. unit} from main menu.
4) Select the {Current Data Display & Save}.
5) Check the door switch input to the body inte-
grated 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 sig-
nal cannot be
detected in some
door switch, Go to
step
2 .
2 CHECK THE 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 har-
ness 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 har-
ness.
3 CHECK THE GROUND CIRCUIT OF DOOR
SWITCH
1) Disconnect the defective door switch har-
ness connector (any of R9, R12, R16, R22).
2) Measure the resistance of harness connec-
tor 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 har-
ness.
4 CHECK DOOR SWITCH.
1) Disconnect the defective door switch har-
ness connector (any of R9, R12, R16, R22).
2) Measure the resistance between door
switch terminals.
Terminals
No. 1 — No. 3:
Is the resistance more than 1
M
Ω
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.
