Diagnostic Trouble Codes
The purpose of the "Diagnostic Trouble Codes" mode is to display stored PCM 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 PCM trouble codes.
When "Clear DTC Information" is selected, a "Clear DTC Information" screen appears. This screen informs you that by clearing DTCs, "all stored DTC information in controller will be erased".
Do you want to clear DTC (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 displayed through F1 mode.
When "Data Display" is selected an "Application Menu" appears. Please select either "Engine" or "Transmission Data Display".
See "Transmission Data" following "Reset Oil Life Monitor.
Snapshot

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. Their 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 PCMCIA memory card. When the Tech 2 is powered down, Snapshots are not lost.
