AUTOMATIC TRANSMISSION (AW30-40LE) 7A–7
CONTROL AND FUNCTIONS
Item Description
Shift and lock-up control • In D range, speed change point and Lock-up point can be changed by
setting pattern selection switch to "POWER", "NORMAL" or "WINTER"
mode.
• Gear shift position in the conditions made up of transmission shift positions
(D.2.L) combined with pattern selection switch (POWER, NORMAL, and
WINTER) can be controlled in accordance with vehicle speed and the
opening of throttle valve.
Overdrive cut control • If O/D OFF switch is set on in D range (O/D OFF lamp ON), gear shift to O/
D is not effected.
• Overdrive is released at O/D OFF switch on and high transmission oil
temperature (More than 130
C).
However, to prevent engine over revolution
•4
3 shifting at vehicle speed is less than 118 km/h.
•3
4 shifting at vehicle speed is more than 131 km/h.
Lock-up cut control • In D range, 3rd or O/D lock-up is conducted in "POWER" or "NORMAL"
mode.
• In 2, L range, lock-up is off in the whole area.
• Lock-up timing is controlled to reduce gear shift shock using kind of gear
shift (shift up, etc.) lock-up status at the time of gear shift judgement, gear
step and throttle opening after gear shift.
• Lock-up is released at brake on or high transmission oil temperature (More
than 130
C).
• Lock-up is prohibited when idling is defected by throttle position sensor.
Driving mode select control • The TCM selects a suitable driving mode from the nine kinds for the variety
driving condition.
i) Economy mode ii) Power mode iii) Winter mode iv) HOT1 mode v) HOT2
mode vi) L4 mode vii) Slope mode (Up slope 1, Up slope 2 and Down
slope mode)
• The priority of driving mode:
Economy < Power < Slope < L4 < Winter < HOT1 < HOT2
Squat control • When the TCM detects D signal on, the TCM controls 1–3–1 shift by
setting a timer, in order to improve the shift feel at N
D.
Line pressure control • The TCM output current which corresponds to throttle oil pressure to
pressure control solenoid based on throttle opening.
Indicate oil temperature warning
function• If the transmission oil temperature sensor senses that transmission oil
temperature is greater than 146
C, the TCM turn on A/T OIL TEMP
warning lamp. (The warning lamp is turned off, if oil temperature is less
than 126
C.)
L4 mode control • The TCM judges whether the transfer is engaged in high or low based on
the ratio rpm data from output speed sensor in the transmission and the
rpm data from speed meter sensor to select the shift map.
Up and down hill control • The TCM judges up and down hill, and change shift pattern based on
throttle opening and acceleration.
Correct oil temperature control • If the temperature exceeds a predetermined value, the TCM selects the
high oil temperature shift point for downshifting, thus preventing the oil
temperature from rising. (More than 130
C, D range)

AUTOMATIC TRANSMISSION (AW30-40LE) 7A–9
MAJOR INPUT/OUTPUT COMPONENTS
Component Function
Input
Vehicle speed sensor (Speedometer) Detects the vehicle speed (Back-up sensor of output
revolution sensor).
Output revolution sensor (Transmission) Detects the vehicle speed.
Input revolution sensor (Transmission) Detects the input revolution (O/D direct clutch drum
revolution).
Engine revolution sensor Detects the engine revolution.
Throttle position sensor Detects the throttle opening rate.
Neutral start switch Detects the select lever position.
Pattern select switch Detects whether the driver has selected "NORMAL",
"POWER", or "WINTER" mode.
Overdrive off switch Detects whether the driver has selected O/D.
Brake lamp switch Detects whether the driver has pressed the brake pedal or
not.
Oil temperature sensor Detects the oil temperature.
Diagnostic star t switch Star ts self-diagnosis and displays a code for faulty part if
any.
Input/Output
Data link connector When connected with Tech2 or tester, can communicate
the data for function check, etc.
Output
Shift solenoid S1, S2 Selects shift point and gear position suited to the vehicle
running condition on the basis of TCM output.
Lock-up control solenoid SL Control the lock-up clutch suited to the vehicle running
condition on the basis of TCM output.
Pressure control solenoid STH Adjusts throttle pressure by energizing current of linear
pressure control solenoid to prevent the shift shock and to
obtain shift smoothly.
"CHECK TRANS" lamp When trouble has occurred to throttle position sensor,
vehicle speed sensor, or solenoid, "CHECK TRANS" lamp
is blinked to warn the driver. If also displays the trouble
code.
A/T OIL TEMP warning lamp Lights when ATF oil temperature rises. (Turned on at
greater than 146
C . Turned off at less than 126C.
Power mode lamp Informs the driver whether the vehicle is in power mode or
not.
Winter mode lamp Informs the driver whether the vehicle is in winter mode or
not.
Computer
Transmission Control Module (TCM) Based on the signal from each switch and sensors, judges
necessary shift point and lock-up operation, and send
signal to each solenoid.

7A–20 AUTOMATIC TRANSMISSION (AW30-40LE)
Once the test vehicle has been identified an “Application
(Power train) Menu" screen appears. Please select the
appropriate application.
The following table shows, which functions are used for
the available equipment versions.
Diagnostic Trouble Codes
The purpose of the “Diagnostic Trouble Codes" mode is
to display stored TCM trouble codes.
When “Diagnostic Trouble Codes" is selected an
“Application Menu" screen appears.
Clear DTC Information
The purpose of the “Clear DTC Information" mode is to
command the clearing of stored TCM trouble codes.
When “Clear DTC Information" is selected, a “Clear
DTC Information", warning screen appears. This screen
informs you that by cleaning DTC's, “all stored DTC
information in controller will be erased".
Do you want to clear DTC's (Yes/No).
Press either the Yes or No key when answering.
After clearing codes, confirm system operation by test
driving the vehicle.
Allow the vehicle to shift through all four forward gears in
a manner which attempts to repeat the failure condition.
NOTE: When the trouble has not been repaired and thetrouble code cannot be erased, check the vehicle again.
DTC Information
When “DTC Information" is selected, an “Application
Menu" appears with a list of DTC information function
keys addressing DTC specifics and their origins.
Function key selections may vary for particular vehicle
and/or system.
Data Display
The purpose of the “Data Display" mode is to
continuously monitor data parameters.
The current actual values of all impor tant sensors and
signals in the system are display through F1 mode.
When “Data Display" is selected an “Application Menu"
appears.
See “TRANSMISSION DATA" and “TCC DATA” on next
page.
Snapshot
When “Snapshot" is selected an “Application Menu"
appears.
When “Transmission Snapshot" application is selected
from the “Application Menu", a “Snapshot Menu"
appears, displaying several options. “Snapshot" options
may vary from one system to another.
“Snapshot" allows a recording of all vehicle parameters.
There parameters may then be replayed at a future
point in time.
This action allows you to focus on making the condition
occur, rather than trying to view all of the data in
anticipation of the fault. The snapshot will collect
parameter information around a trigger point that you
select.
When a snapshot is taken. It is recorded onto the
PCMCIA memory card. When the Tech2 is powered
down. Snapshots are not lost.
Actuator Tests
The purpose of “Actuator Tests" mode is to check for
correct operation of electronic system actuators.
