SFreeze frame data:
The freeze frame data records the engine conditions (fuel
system, calculated load, engine coolant temperature, fuel
trim, engine speed, vehicle speed, etc.) when a malfunc-
tion is detected. When troubleshooting, freeze frame data
can help determine if the vehicle was running or stopped,
if the engine was warmed up or not, if the air−fuel ratio
was lean or rich, and other data from the time the malfunc-
tion occurred.
3. CHECK DLC3.
(a) The vehicle’s ECM uses the ISO 9141−2 (Euro−OBD)/
ISO14230(M−OBD) communication protocol. The termi-
nal arrangement of the DLC3 complies with ISO
15031−03 and matches the ISO 9141−2/ ISO14230 for-
mat.

HINT:
If your display shows ”UNABLE TO CONNECT TO VEHICLE”
when you have connected the cable of hand−held tester to the
DLC3, turned the ignition switch to the ON position and oper-
ated the hand−held tester, there is a problem on the vehicle side
or tool side.
SIf communication is normal when the tool is connected to
another vehicle, inspect DLC3 on the original vehicle.
SIf communication is still not possible when the tool is con-
nected to another vehicle, the problem is probably in the
tool itself, so consult the Service Department listed in the
tool’s instruction manual.
4. INSPECT BATTERY VOLTAGE
(a) Measure the battery voltage.
Battery Voltage:11to14V
If the voltage is below11V, recharge the battery before pro-
ceeding.

PROBLEM SYMPTOMS TABLE
HINT:
If a normal code is displayed during the diagnostic trouble code check although the trouble still occurs, check
the electrical circuits for each symptom in the order given in the charts on the following pages and proceed
to the page given for troubleshooting.
The Matrix Chart is divided into 2 chapters.
1. Chapter 1: Electronic Circuit Matrix Chart
S Refer to the table below when the trouble cause is considered to be electrical.
S If the instruction ”Proceed to next circuit inspection shown on matrix chart” is given in the flow chart
of each circuit, proceed to the circuit with the next highest number in the table to continue the check.
S If the trouble still occurs even though there are no abnormalities in any of the other circuits, check and
replace the ECM.

MANUAL SHIFTING TEST
1. PERFORM MANUAL SHIFTING TEST
HINT:
S With this test, it can be determined whether the trouble oc-
curs in the electrical circuit or is a mechanical problem in
the transaxle.
S If any abnormalities are found in the following test, the
problem is in the transaxle itself.
(a) Disconnect the transmission wire connector.
(b) Drive with the transmission wire disconnected. Shifting the shift lever to the D position to check whether
the shifting condition changes the table below.
Shift PositionShifting Condition
DNo Shift (Not Change)
HINT:
When driving with the transmission wire disconnected, the gear
position will be as follows:
S When the shift lever is in the D position, the gear is held
in the 4th position.
S When the shift lever is in the R or the P position, the gear
is also in the R or the P position respectively.
(c) Connect the transmission wire connector.

NOTICE:
SPerform the test at the normal operation fluid temper-
ature the 50 to 80˚C(122 to176˚F)
SThe line pressure test should always be carried out in
pairs. One technician should observe the conditions
of wheels or wheel stoppers outside the vehicle while
the other is performing the test.
SBe careful to prevent SST hose from interfering with
the exhaust pipe.
SThis check must be conducted after checking and ad-
justing engine.
SPerform under condition that A/C is OFF.
SWhen conducting stall test, do not continue more
than10 seconds.
(1) Warm up the ATF (Automatic Transmission Fluid).
(2) Lift the vehicle up.
(3) Remove the engine under cover.

There is a difference in installation point between D posi-
tion and R position.
(6) Start the engine.
(7) Using hand−held tester, shift to D position and hold
3rd gear by active test, and measure the line pres-
sure in idling.
Specified line pressure:

tion, depress the accelerator pedal all the way down
and check the line pressure while the stall test is
performed.

(14) Remove the test plug B, install the SST and start en-
gine.

(15) Connect the transmission wire connector, depress
the brake pedal firmly, shift to the R position and
check that the line pressure while the engine is id-
ling and during the stall test.
Specified line pressure:
