KEY CONFINEMENT PREVENTION FUNCTION DOES NOT WORK
PROPERLY (UNLOCK WARNING SWITCH CIRCUIT)
CIRCUIT DESCRIPTION
The unlock warning switch turns on when the key is inserted in the ignition key cylinder and the door courtesy
switch turns on when the driver’s door is opened, and the integration relay monitors both switches conditions.
According to these switches conditions, the integration relay controls the door locking operation not to lock
the doors while both switches are on, in order to prevent the key from being confined.

CHECK FOR INTERMITTENT PROBLEMS
Hand-held tester only:
By putting the vehicle’s ECM in the check mode, the 1 trip detection logic is possible instead of the
2 trip detection logic, and the sensitivity to detect faults is increased. This makes it easier to detect
intermittent problems.
(a) Clear the DTCs (See page 05-11).
(b) Set the check mode (See page 05-11).
(c)
Perform a simulation test (See page 01-20).
(d) Check the connector and terminal (See page 01-30).
(e) Wiggle the harness and connector (See page 01-30).

CHECK MODE PROCEDURE
HINT:
Hand-held tester only:
Compared to the normal mode, the check mode has more sens-
ing ability to detect malfunctions. Furthermore, the same diag-
nostic items which are detected in the normal mode can also be
detected in the check mode.
1.
CHECK MODE PROCEDURE(Using the hand-held
Hand-held Tester
tester)
(a) Check the initial 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 switched OFF
DLC3
(b) Turn the ignition switch OFF.
A79121
(c)
Connect the hand-held tester to the DLC3.
(d) Turn the ignition switch ON.
(e) Switch the hand-held tester from the normal mode to the
check mode (check that the MIL flashes).
0.13 sec.
NOTICE:
ON
If the hand-held tester switches the ECM from the normal
mode to the check mode or vice-versa, or if the ignition
switch is turned from ON to ACC or OFF during the check
OFF
mode, the DTC and freeze frame data will be erased.
(f)
Start the engine (MIL goes off after the engine starts).
0.13 sec.
A76900
(g) Simulate the conditions of the malfunction described by
the customer.
NOTICE:
Leave the ignition switch ON until you have checked the
DTC, etc.
(h) After simulating the malfunction conditions, check the
DTC and freeze frame data, etc using the hand-held tes-
ter diagnosis selector.
HINT:
Do not turn the ignition switch OFF, as turning it OFF switches
the diagnosis system from the check mode to the normal mode,
which erases all the DTCs, etc.
(i)
After checking the DTC, inspect the applicable circuit.
2.
CLEAR DTC (Using the OBD II scan tool or hand-held
tester)
(a) Connect the OBD II scan tool or hand-held tester to the
DLC3.
(b) Turn the ignition switch ON.
(c)
Operate the OBD II scan tool or hand-held tester to erase
the codes. All the DTCs and freeze frame data will be
erased. (See the OBD II scan tool’s manual book for
operating manuals.)

held tester)
(a) Disconnect the battery terminal or remove the EFI fuse
from the engine room R/B for more than 60 seconds.

By comparing the Parameter VALUE to the TEST LIMIT,
it is possible to determine the degree of failure.

DIAGNOSTICS

F
In rare cases, the monitor may have passed even with a
DTC set and MIL illuminated. The monitor may have
failed on a previous trip, and then passed on the most re-
cent trip. This would indicated an intermittent problem
may be the cause of the DTC.
