Step
4 CHECK POWER WINDOW MAIN SWITCH
OUTPUT SIGNAL.
Measure the voltage between the harness con-
nector terminal of power window main switch
and chassis ground when moving the door lock
switch to UNLOCK.
Connector & terminal
(D7) No. 5 (+) — Chassis ground (
5 CHECK DOOR LOCK ACTUATOR.
Check the door lock actuator.
• Front Door Lock Actuator <Ref. to SL-31,
Front Door Lock Actuator.>
• Rear Door Lock Actuator <Ref. to SL-35,
Rear Door Lock Actuator.>
• Rear Gate Latch Lock Actuator <Ref. to SL-
37, Rear Gate Latch Assembly.>
6. CHECK KEY CYLINDER LOCK SWITCH AND CIRCUIT
Step
1 CHECK KEY CYLINDER LOCK SWITCH CIR-
CUIT.
1) Disconnect the body integrated unit har-
ness connector.
2) Measure the resistance between harness
connector terminal and chassis ground when
turning the key cylinder lock switch to LOCK.
Connector & terminal
(i84) No. 3 — Chassis ground:
2 CHECK KEY CYLINDER LOCK SWITCH CIR-
CUIT.
Measure the resistance between harness con-
nector terminal and chassis ground when turn-
ing the key cylinder lock switch to UNLOCK.
Connector & terminal
(i84) No. 12 — Chassis ground:
3 CHECK KEY CYLINDER LOCK SWITCH.
1) Disconnect the key cylinder lock switch
connector.
2) Measure the resistance between key cylin-
der lock switch terminals when turning the key
cylinder lock switch to LOCK.
Terminals
No. 1 — No. 2
4 CHECK KEY CYLINDER LOCK SWITCH.
Measure the resistance between key cylinder
lock switch terminals when turning the key cyl-
inder lock switch to UNLOCK.
Terminals
No. 2 — No. 3
