OPERATION CHECK
1. CHECK ELECTRICAL DOOR LOCK OPERATION
(a) Check the basic function.
(1) Check that all doors lock when the door control
switch (for manual operation) is turned to LOCK
and all doors unlock when turned to UNLOCK.
(2) Check that all doors lock when the driver side
door lock key cylinder is turned to LOCK using
the key.
(3) Check that only the driver side door unlocks
when the driver side door lock key cylinder is
turned to UNLOCK and all doors unlock when
turned to UNLOCK once again within 3 seconds
using the key (2-step unlocking function).
(b) Check the key lock-in prevention.
NOTICE:
In order to prevent the key from being actually
locked-in, the inspection should be made with
the driver side door window open.
(1) Have the key inserted into the ignition key
cylinder.
(2) With the driver side door open, check that all
doors unlock immediately after the door lock
knob for the driver side door is turned to LOCK.
(3) With the driver side door open, check that all
doors unlock immediately after the door control
switch (for manual operation) is turned to LOCK.
(4) With the driver side door open, turn the driver
side door lock knob to LOCK and hold it for 2
seconds or more, and then close the driver side
door. Then check that all doors unlock.

DIAGNOSIS SYSTEM
1. DESCRIPTION
Power door lock control system data can be read in the
Data Link Connector 3 (DLC3) of the vehicle. When the
system seems to be malfunctioning, use the intelligent
tester to check for malfunctions and perform repairs.
2. CHECK DLC3
(a) The ECU uses ISO 15765-4 for communication.
The terminal arrangement of the DLC3 complies
with ISO 15031-3 and matches the ISO 15765-4
format.
NOTICE:
*: Before measuring the resistance, leave the
vehicle for at least 1 minute and do not operate
the ignition switch, any switches or doors.
If the result is not as specified, the DLC3 may have
a malfunction. Repair or replace the harness and
connector.
HINT:
Connect the cable of the intelligent tester to the
DLC3, turn the ignition switch ON and attempt to
use the tester. If the display indicates that a
communication error has occurred, there is a
problem either with the vehicle or with the tester.
• If communication is normal when the tester is
connected to another vehicle, inspect the DLC3
of the original vehicle.
• If communication is still not possible when the
tester is connected to another vehicle, the
problem may be in the tester itself. Consult the
Service Department listed in the tester's
instruction manual.
