Part 2:
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 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. Please select either "Engine" or "Transmission Data Display".
See "Transmission 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 Tech 2 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: none
Solenoid
Solenoid 1-2/3-4, Solenoid 2-3, TCC Solenoid
You can operate the solenoids by pressing the "ON" and "OFF" buttons.
Preconditions: P-N position, no vehicle speed, no engine speed
Pressure Control Solenoid (PCS)
You can set desired PCS Current using the "Increment" (+20) and "Decrement" (-20) button. The PC Solenoid Data informs about PCS Current, Pressure and Duty Cycle.
Preconditions: P-N position, no engine speed, no vehicle speed
NOTE: 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 MIL is commanded on. These data can help to identity the cause of a fault. Refer to Storing And Erasing Freeze Frame Data for more detailed information.

2. Transfer the snapshot data to PC.
After recording the snapshot in Tech 2, transfer the data from Tech 2 to PC by the below procedures.
1. Start TIS2000.
2. Select "Snapshot Upload" on the TIS2000 start screen.
3. Select "Upload from trouble diagnosis tool (transfer from diagnosis tester)" or click the corresponding icon of the tool bar.
4. Select Tech 2, and transfer the recorded snapshot information.
5. Select the transferred snapshot.
6. After ending transfer of the snapshot, data parameter list is displayed on the screen.
3. Snapshot data is displayed with TIS2000 "Snapshot Upload" function.
Snapshot is stored in the PC hard disk or floppy disk, and can be displayed any time.
Stored snapshot can be displayed by the below procedures.
1. Start TIS2000.
2. Select "Snapshot Upload" on the TIS2000 start screen.
3. Select "Open the existing files" or click the corresponding icon of the tool bar.
