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 “Clea
r
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
the trouble 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 important sensors and
signals in the system are display through F1 mode.
When “Data Display" is selected an “Application 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 Tech 2 is powered
down. Snapshots are not lost.

about PCS Current, Pressure and Duty Cycle.
Preconditions: P –N position, no engine speed, no
vehicle speed
NOTE: Freeze Frame
Freeze Frame is an element of the Diagnostic
Management System which stores various vehicle
information at the moment an emission-related fault
is stored in memory and when the Check Transe
Lamp is commanded on. These data can help to
identity the cause of a fault. Refer to Storing An
d

this procedure.
8.
During obtaining information, Tech-2 is receiving
information from the control unit chosen. In
replacing the control unit, please be sure to
undertake "Obtaining Information" from the new
unit. With VIN not being programmed into the new
control unit at the time of shipment, "obtaining
information" is not complete (because the vehicle
model, engine model and model year are specified
from VIN). For the procedure get additional
information on vehicles, instruction will be
provided in dialog form, when TIS2000 is in
operation.
9.
Following instructions by Tech-2, push the "Exit"
switch of Tech-2, turn off the ignition of the vehicle
and turn off the power of Tech-2, thereby
removing from the vehicle.

3.Data Exchange
