3. 2 TRIP DETECTION LOGIC
When a malfunction is first detected, the malfunction is
temporarily stored in the ECM memory (1st trip). If the
same malfunction is detected during the next
subsequent drive cycle, the MIL is illuminated (2nd trip).
4. FREEZE FRAME DATA
Freeze frame data records the engine conditions (fuel
system, calculated engine load, engine coolant
temperature, fuel trim, engine speed, vehicle speed,
etc.) when malfunctions are detected. When
troubleshooting, freeze frame data can help determine if
the vehicle was moving or stationary, if the engine was
warmed up or not, if the air-fuel ratio was lean or rich,
and other data from the time the malfunction occurred.
5. DLC3 (Data Link Connector 3)
CAUTION:
*: Before measuring the resistance, leave the vehicle
as is for at least 1 minute and do not operate the
ignition switch, any other switches or the doors.
If the result is not as specified, the DLC3 may have a
malfunction. Repair or replace the harness and
connector.
HINT:
The DLC3 is the interface prepared for reading various
data from the vehicle's ECM. After connecting the cable
of the intelligent tester to the CAN VIM, turn the ignition
switch ON and turn the tester ON. If a communication
failure message is displayed on the tester screen (on the
tester: UNABLE TO CONNECT TO VEHICLE), a
problem exists in either the vehicle or tester. In order to
identify the location of the problem, connect the tester to
another vehicle.

FREEZE FRAME DATA
1. DESCRIPTION
Freeze frame data records the engine conditions (fuel
system, calculated load, engine coolant temperature,
fuel trim, engine speed, vehicle speed, etc.) when a
malfunction is detected. When troubleshooting, it can
help determine if the vehicle was running or stopped, the
engine was warmed up or not, the air-fuel ratio was Lean
or Rich, and other data from the time the malfunction
occurred.
HINT:
If it is impossible to duplicate the problem even though a
DTC is detected, confirm the freeze frame data.
The ECM records engine conditions in the form of freeze
frame data every 0.5 seconds. Using the intelligent
tester, 5 separate sets of freeze frame data can be
checked.
– 3 data sets before the DTC was set.
– 1 data set when the DTC was set.
– 1 data set after the DTC was set.
These data sets can be used to simulate the condition
of the vehicle around the time of the occurrence of the
malfunction. The data may assist in identifying the
cause of the malfunction, and in judging whether it
was temporary or not.

SE–4SEAT – FRONT POWER SEAT CONTROL SYSTEM
SE
NOTICE:
• The inspection should be performed with the
seat installed in the vehicle.
• Perform the 4 steps below for the full range of
motion for each power seat function.
(1) Choose a power seat function. Operate the
power seat switch and move the seat as much
as possible in one direction. Keep the seat in
that position for approximately 60 seconds.
(2) Operate the power seat switch again and
continue to try to move the seat in the same
direction as in the previous step. Measure the
amount of time elapsed before current is
automatically cut (the sound of the motor has
stopped).
Standard:
4 to 90 seconds
(3) After current has been cut, release the power
seat switch and wait for approximately 60
seconds.
(4) Operate the same power seat switch and move
the seat in the opposite direction. Check that
the motor operates.
3. CHECK LUMBAR SUPPORT ADJUSTER ASSEMBLY
(a) Check the PTC operation inside the power seat
motor.
NOTICE:
The inspection should be performed with the
seat installed in the vehicle.
(1) Operate the lumbar support switch and move
the lumbar support to either the foremost or
rearmost position. Keep the seat in that
position for approximately 60 seconds.
(2) Operate the lumbar support switch again and
continue to try to move the lumbar support in
the same direction as in the previous step.
Measure the amount of time elapsed before
current is automatically cut (the sound of the
motor has stopped).
Standard:
4 to 90 seconds
(3) After current has been cut, release the lumbar
support switch and wait for approximately 60
seconds.
(4) Operate the lumbar support switch and move
the seat in the opposite direction. Check that
the motor operates.

(7) Change the transmission to 2nd gear.
(8) Accelerate the vehicle to 64 km/h (40 mph) or
more by depressing the accelerator pedal for at
least 10 seconds.
(9) Soon after performing step (8) above, release
the accelerator pedal for at least 4 seconds without
depressing the brake pedal in order to execute fuel-
cut control.
(10) Allow the vehicle to decelerate until the vehicle
speed declines to less than 10 km/h (6 mph).
(11) Repeat steps from (8) through (10) above at
least 3 times in one driving cycle.
(c) Monitor Status
(1) Check the Readiness Monitor status displayed
on the tester.
(2) If the status does not switch to COMPL
(complete), make sure that the preconditions
have been met, and then perform steps from (5)
through (11) in the Drive Pattern above.
