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.

HINT:
*: Drive at such a speed in the uppermost gear to engage
lock-up. The vehicle can be driven at a speed lower than the
speed shown in the above diagram under the lock-up
condition.
NOTICE:
It is necessary to drive the vehicle for approximately 30
minutes to detect DTC P0711 (Transmission fluid
temperature sensor "A" performance).

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.
CHAPTER 1: ELECTRICAL CIRCUIT MATRIX CHART
HINT:
*: When the circuit is defective, a DTC may be output.

TERMINALS OF ECM
1. CHECK ECM
(a) Measure the voltage of the ECM connector.
HINT:
Each ECM terminal's standard voltage is shown in
the table below.
In the table, first follow the information under
"Condition". Look under "Symbols (Terminal No.)"
for the terminals to be inspected. The standard
voltage between the terminals is shown under
"Specified Condition".
Use the illustration above as a reference for the
ECM terminals.
