Without double lock:
(B176) No. 10 — Chassis ground:
With double lock:
(B325) No. 7 — Chassis ground:
Is the resistance less than 10
Ω?
Go to step 2. Go to step 3.
2 CHECK DOOR LOCK SWITCH CIRCUIT.

connector terminal and chassis ground when
the door lock switch is moved to UNLOCK.
Connector & terminal
Without double lock:
(B176) No. 8 — Chassis ground:
With double lock:
(B325) No. 4 — Chassis ground:

4 CHECK DOOR LOCK SWITCH.
Measure the resistance between the door lock
switch terminals when moving the door lock
switch to UNLOCK.
Connector & terminal
LHD model:
(D7) No. 5 — No. 8
RHD model:
(D7) No. 16 — Switch ground:

Ω?
Check the harness
for open circuits or
shorts between
