MANUAL SHIFTING TEST
1. MANUAL SHIFTING TEST
HINT:
• Through this test, it can be determined whether the
trouble occurs in the electrical circuit or if it is a
mechanical problem in the transaxle.
• If any abnormalities are found in the following test, the
problem is in the transaxle itself.
(a) Disconnect the connector of the transmission wire.
HINT:
It is possible to deactivate the electrical shift control
by disconnecting the transmission wire. The gear
positions can then be changed mechanically with
the shift lever.
(b) Drive with the transmission wire disconnected.
Move the shift lever to each position to check
whether the gear position changes as shown in the
table below.
HINT:
While driving with the transmission wire
disconnected:
• When the shift lever position is in L or 2, the gear
position is held in 3rd.
• When the shift lever position is in 3, 4 or D, the
gear position is held in 4th.
• When the shift lever position is in R or P, the
operation is the same as usual.
(c) Connect the connector of the transmission wire.
(d) Clear the DTC (see page AX-33).

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.

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.
Terminal of DLC3
NOTICE:
*: 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.
