ROAD TEST
1. PROBLEM SYMPTOM CONFIRMATION
(a) Based on the result of the customer problem
analysis, try to reproduce the symptoms. If the
problem is that the transaxle does not shift up, shift
down, or the shift point is too high or too low,
conduct the following road test referring to the
automatic shift schedule and simulate the problem
symptoms.
2. ROAD TEST
NOTICE:
Perform the test at the normal operating ATF
temperature of 50 to 80
C (122 to 176F).
(a) D position test
Move the shift lever to D and fully depress the
accelerator pedal. Check the following:
(1) Check up-shift operation.
Check that the 1
2, 2 3 and 3 O/D up-
shifts take place at the shift point shown in the
automatic shift schedule (see page SS-55).
HINT:
O/D Gear Up-shift Prohibition Control
• Engine coolant temperature is 55
C (131F)
or less and vehicle speed is at 70 km/h (43
mph) or less.
• ATF temperature is 5
C (41F) or less.
O/D Gear Lock-up Prohibition Control
• Brake pedal is depressed.
• Accelerator pedal is released.
• Engine coolant temperature is 60
C (140F)
or less.
(2) Check for shift shock and slip.
Check for shock and slip at the 1
2, 2 3 and
3
O/D up-shifts.
(3) Check for abnormal noise and vibration.
Check for abnormal noise and vibration when
up-shifting from 1
2, 2 3 and 3 O/D while
driving with the shift lever on D, and check while
driving in the lock-up condition.
HINT:
The check for the cause of abnormal noise and
vibration must be done thoroughly as it could
also be due to loss of balance in the differential,
torque converter clutch, etc.
(4) Check kick-down operation.
While driving the vehicle in the 2nd, 3rd and O/D
gears with the shift lever on D, check that the
possible kick-down vehicle speed limits for 2

1, 3
2 and O/D 3 kick-downs conform to
those indicated in the automatic shift schedule
(see page SS-55).
(5) Check for abnormal shock and slip at kick-down.

MONITOR DRIVE PATTERN
1. TEST MONITOR DRIVE PATTERN FOR ECT
CAUTION:
Perform this drive pattern on a level surface and
strictly observe the posted speed limits and traffic
laws while driving.
HINT:
Performing this drive pattern is one method to simulate
the ECT's malfunction detection conditions.
The DTCs may not be detected through ordinary,
everyday driving. Also, DTCs may not be detected
through this drive pattern.
(a) Preparation for driving
(1) Warm up the engine sufficiently (engine coolant
temperature is 60
C (140F) or higher).
(2) Drive the vehicle when the atmospheric
temperature is -10
C (14F) or higher.
Malfunction is not detected when the
atmospheric temperature is less than -10
C
(14
F).
(b) Drive pattern
(1) Drive the vehicle through all the gears.
St o p
1st 2nd 3rd O/D O/D (lock-up
ON).
(2) Repeat the above drive pattern 3 times or more.
NOTICE:
• When using the intelligent tester, the
monitor status can be found in
"ENHANCED OBD II / DATA LIST" or under
"CARB OBD II".
• In the event that the drive pattern must be
interrupted (due to traffic conditions or
other factors), the drive pattern can be
resumed and, in most cases, the monitor
can be completed.
CAUTION:
Perform this drive pattern on a level road as
much as possible and strictly observe the
posted speed limits and traffic laws while
driving.

PROBLEM SYMPTOMS TABLE
HINT:
• Use the table below to help determine the cause of the
problem symptom. The potential causes of the symptoms
are listed in order of probability in the "Suspected area"
column of the table. Check each symptom by checking the
suspected areas in the order they are listed. Replace parts
as necessary.
• The Matrix Chart is divided into 2 chapters. When
troubleshooting, check Chapter 1 first. If instructions are
given in Chapter 1 to proceed to 2, proceed as instructed.
• If the instruction "Proceed to next circuit inspection shown
in problem symptoms table" is given in the flowchart for
each circuit, proceed to the next suspected area in the
table.
• If the problem still occurs even though there are no
malfunctions in any of the circuits, check the ECM and
replace it if necessary.

4. FREEZE FRAME DATA
(a) 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, 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
malfunction occurred.
(b) The intelligent tester records freeze frame data in 5
different instances: 1) 3 times before the DTC is set,
2) once when the DTC is set, and 3) once after the
DTC is set. These data can be used to simulate the
vehicle's condition around the time when the
malfunction occurred. The data may help find the
cause of the malfunction, or judge if the DTC is
being caused by a temporary malfunction or not.
5. DATA LINK CONNECTOR 3 (DLC3)
(a) The vehicle's ECM uses the ISO 15765-4 for
communication protocol. The terminal arrangement
of the DLC3 complies with SAE J1962 and matches
the ISO 15765-4 format.
HINT:
*: Before measuring the resistance, leave the vehicle as is for
at least 1 minute and do not operate the ignition switch, other
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
screen displays UNABLE TO CONNECT TO VEHICLE, a
problem exists in the vehicle side or the tester side.
