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.

DATA LIST / ACTIVE TEST
1. READ DATA LIST
HINT:
Using the intelligent tester's DATA LIST allows switch,
sensor, actuator and other item values to be read without
removing any parts. Reading the DATA LIST early in
troubleshooting is one way to save time.
(a) Connect the intelligent tester (with CAN VIM) to the
DLC3.
(b) Turn the ignition switch ON.
(c) Read the DATA LIST on the tester's screen.

2. PERFORM ACTIVE TEST
HINT:
Performing the intelligent tester's ACTIVE TEST allows
relay, VSV, actuator and other items to be operated
without removing any parts. Performing the ACTIVE
TEST early in troubleshooting is one way to save time.
The DATA LIST can be displayed during the ACTIVE
TEST.
(a) Connect the intelligent tester (with CAN VIM) to the
DLC3.
(b) Turn the ignition switch ON.
(c) Perform the ACTIVE TEST according to the display

CHECK MODE PROCEDURE
HINT:
Intelligent tester only:
Compared to normal mode, check mode is more sensitive to
malfunctions. Therefore, check mode can detect the
malfunctions that cannot be detected by normal mode.
NOTICE:
All the stored DTCs and freeze frame data are erased if:
1) the ECM is changed from normal mode to check mode
or vice versa; or 2) the ignition switch is turned from ON
to ACC or OFF while in check mode. Before changing
modes, always check and make a note of any DTCs and
freeze frame data.
1. CHECK MODE PROCEDURE (Using intelligent
tester)
(a) Check and ensure the following conditions:
(1) Battery positive voltage 11 V or more.
(2) Throttle valve fully closed.
(3) Transmission in the P or N position.
(4) A/C switch OFF.
(b) Turn the ignition switch OFF.
(c) Connect the intelligent tester to the DLC3.
(d) Turn the ignition switch ON.
(e) Turn the tester ON.
(f) Select the following menu items: DIAGNOSIS /
ENHANCED OBD II/ CHECK MODE.
(g) Switch the ECM from normal mode to check mode.
(h) Make sure the MIL flashes as shown in the
illustration.
(i) Start the engine.
(j) Make sure the MIL turns off.
(k) Simulate the conditions of the malfunction described
by the customer.
(l) Check DTCs and freeze frame data using the tester.

FAIL-SAFE CHART
If any of the following DTCs are set, the ECM enters fail-safe
mode to allow the vehicle to be driven temporarily.
HINT:
*: The vehicle can be driven slowly when the accelerator
pedal is depressed firmly and slowly. If the accelerator pedal
is depressed quickly, the vehicle may speed up and slow
down erratically.
