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.
Lamps
You can operate the lamps by pressing the ON and OFF
buttons.
Preconditions: P or N position
Solenoid
Solenoid S1(1-2/3-4), S2(2-3) and TCC Solenoid
(Torque Converter Clutch)
You can operate the solenoids by pressing the ON and
OFF buttons.
Preconditions: P or N position, no vehicle speed, no
engine speed
Pressure Control Solenoid (PCS)
You can operate the PC Solenoid by pressing the ON
and OFF buttons. ON will command a maximum current
of 1000 mA and OFF a minimum of 200 mA.
Preconditions: P or N position, no vehicle speed, engine

ROAD TEST
NOTE:
Perform the test at normal operation fluid temperature (50
– 80
C or 122 – 176F).
"D" RANGE TEST IN "NORMAL", AND "POWER"
PATTERN RANGES
Shift into the "D" range and hold the accelerator pedal constant
at the 50% and 100% throttle valve opening positions.
Push in one of the pattern selector buttons and check the
fol lowing:
1) 1-2, 2-3, 3-OD and lock-up, up-shifts should take place,
and shift points should conform to those shown in the
automatic shift diagram.
NOTE:
Drive the vehicle on level ground so as not to change to up
and down hill control.
EVALUATION
(1) If there is no 1
2 up-shift:
• No. 2 solenoid is stuck
• 1-2 shift valve is stuck
(2) If there is no 2
3 up-shift:
• No. 1 solenoid is stuck
• 2-3 shift valve is stuck
(3) If there is no 3
OD up-shift (throttle valve opening 1/2):
• No. 2 solenoid is stuck
• 3-4 shift valve is stuck
(4) If the shift point is defective:
Refer to
"TROUBLESHOOTING CHART" in this section.
(5) If the lock-up is defective:
Refer to
"TROUBLESHOOTING CHART" in this section.
2) In the same manner, check the shock and slip at the 1 2,
2
3 and 3 OD up-shifts.
EVALUATION
If the shock is excessive:
Refer to
"TROUBLESHOOTING CHART" in this section.
