Using This Manual

To increase their effectiveness with the Tech2, users should familiarize themselves with the format and information contained in this guide.

Vehicle System Familiarity

While the Tech2 is a powerful tool, it cannot replace knowledge and skill. To obtain maximum benefit from the Tech2, service technicians must have a complete understanding of vehicle systems.

When using the Tech2 to diagnose a vehicle, it is recommended that service technicians also refer to the service manual and the latest service bulletins.

Disclaimer

The Tech2 is designed for use by trained service personnel only. It has been developed for the sole purpose of diagnosing and repairing automotive systems with electronic controls and interfaces.

Every attempt has been made to provide complete and accurate technical information based on factory service information available at the time of publication. However, the right is reserved to make changes at any time without notice.

Things You Should Know

CAUTION: EXHAUST GAS

When performing any checks with the engine running in an enclosed space such as a garage, ensure proper ventilation. Never inhale exhaust gases; they contain carbon monoxide—a colorless, odorless, extremely dangerous gas that can cause unconsciousness or death.

CAUTION: PARKING BRAKE

To help avoid personal injury, always set the parking brake securely and block the drive wheels before performing any checks or repairs on the vehicle.

CAUTION: SPARKS

The Tech2 uses parts that can produce arcs or sparks. When used in a garage environment, the Tech2 must be located not less than 18 inches (460 mm) above the floor.

NOTICE:

• DO NOT clasp battery clamps together when connected simultaneously to the

vehicle’s 12 volt cigarette lighter or power supply. Reverse polarity in the vehicle’s

cigarette lighter may be present. Damage could occur to the Tech2 or to the vehicle.

• If power is applied to the Tech2 and the display remains blank, reverse polarity in the

cigarette lighter may be present. Damage to the Tech2 could occur. DO NOT connect the DLC cable to the vehicle. Verify that the center contact of the vehicle’s cigarette lighter has +12 volts and that the outer contact is grounded.

• Turn off the power before inserting or removing the PCMCIA card. Continual removal

and reinsertion of this card is not recommended.

• Align all cards and components carefully before inserting them into the Tech2

• Do not place the Tech2 so that the tilt stand can make contact with the vehicle

battery terminal as this could short out the battery.

Care & Cleaning

After using the Tech2, a few simple steps will insure that you get the most life out of this diagnostic tool.

NOTICE: Do not spray or pour cleaner anywhere on the Tech2. If the Tech2 should become dirty, clean it with a mild detergent or hand soap. Avoid using harsh solvents such as petroleum-based cleaning agents: acetone, benzene, trichlorethylene, etc. Harsh solvents can etch Tech2 plastic surfaces.

Although the Tech2 is water resistant it is not waterproof, so be sure to thoroughly dry off the Tech2 prior to usage and/or storage.

Maintenance of the Tech2 requires periodic inspection and cleaning of:

• The display window

• The keypad

• The cable assemblies and connectors

Make sure the Tech2 is not connected to a vehicle or other power source and follow the cleaning procedures detailed below.

Cleaning the Display

The display collects dust and grime during normal use. Occasionally wipe the screen with a clean, soft, static-free cloth. Remove stubborn stains by applying a non-abrasive glass cleaner to a soft cloth and wipe cloth across display area.

Cleaning the Keypad

Clean the keypad with a non-abrasive cleaner. Apply a small amount of cleaner on a soft cloth and wipe cloth across keypad area.

Maintaining the Cable Assemblies and Connectors

Inspect cable assemblies during connection and disconnection to components. Watch for any cuts or abrasions along the cables. Check the connectors and connector pins for grease, dirt and corrosion. If contaminants are present, remove them with a mild soap solution.

Storing the Tech2

• Store the Tech2 away from solvents and other liquids. It is NOT moisture proof.

• Store the Tech2 away from direct sunlight. Ultraviolet and infrared light will darken

the display.

• Store the Tech2 in its plastic case. Otherwise, the high-impact plastic cover could become scratched.

General Motors Tech2 User Guide

Getting Started

This section covers all Tech2 vehicle applications. Therefore, some of the information provided may not be required for individual applications.

The Tech2 contains two serial communication ports: the RS-232 and the RS-485. Use the RS-232 port for downloading data from another computer to the Tech2. The RS-485 port is currently not used.

The Tech2 also contains two PCMCIA ports, a power jack connector, and a Vehicle Communications Interface (VCI) connector. One of the PCMCIA slots contains a memory card with diagnostic information. The power jack accepts power from the AC/DC power supply, battery, or cigarette lighter power cable. The VCI connector accepts the DLC cable or DLC loopback adapter.

Notice: When using the Tech2 for vehicle communications, the power jack must be connected to the Tech2 DLC loopback adapter

Identification of the Tech2’s external ports

Initial Hardware Installation

The Tech2 hardware initial installation requires the following seven tasks:

1. Remove the RS-232 loopback adapter (P/N 3000112) from the storage case (P/N

3000116). Plug it into the RS-232 port

General Motors Tech2 User Guide

2. Attach the Tech2 DLC cable (P/N 3000095) to the VCI connector

General Motors Tech2 User Guide

3. Locate the DLC loopback adapter (P/N 3000109) in the storage case. Attach it to the DLC cable

General Motors Tech2 User Guide

4. Locate the NAO (P/N 3000113) or Universal (P/N 3000115) power supply and appropriate power cord in the storage case. Insert the power jack into the Tech2 DLC cable or into the bottom of the Tech2 next to DLC cable connector.

Tech2 Keypad

The Tech2 keypad consists of six major keypad operation areas:

1. Control keys (SHIFT, PWR)

2. Soft keys

3. Selection (arrow) keys

4. Action keys (YES, NO, ENTER, EXIT)

5. Function keys (F0 to F9)

6. Help (?) key

Control Keys

The [PWR] key is used to turn the Tech2 on or off. The status indicator light above this key will be illuminated green when the Tech2 is operational.

The [SHIFT] key is used with the up and down arrow keys to change screen brightness and contrast. To adjust screen brightness and contrast, perform the following:

• Press the [SHIFT] key once (amber status indicator light above [SHIFT] should light

up).

General Motors Tech2 User Guide

• Use up and down arrows to adjust screen brightness and contrast: Press up arrow

key to increase screen brightness and contrast.

Press down arrow key to decrease screen brightness and contrast.

• Press [SHIFT] key again when desired brightness is reached (status indicator light

above [SHIFT] should now be off).

The Tech2 should return to normal operation after following the above steps.

Tech2 keypad Location of control keys

Soft Keys

Four soft keys are located directly below the Tech2 screen. The soft keys correspond directly to the four possible selection boxes found at the bottom region of the Tech2 screen. These selections may change from screen to screen and are under the control of the application software. To make a screen selection, press the corresponding soft key. In the example shown, the first soft key was pressed to select [Display Time].

Selection Keys

The Tech2 selection keys are four directional arrow keys. Press the arrow keys to move the highlighted area to a selection on the screen or to scroll the screens if more than one. Once the desired selection is highlighted, press [ENTER] to activate the selection.

General Motors Tech2 User Guide

Action Keys

Action keys are used to respond to a specific question, initiate an action, or to exit from the Tech2 program. Specific “yes or no” questions will often appear on the Tech2 screen. The [YES] and [NO] keys are used to respond to these questions. Either of the two [ENTER] keys may be pressed to activate a menu selection. Either of the two [EXIT] keys may be pressed to leave the current Tech2 screen and return to a previous screen.

Function Keys

Ten function keys (F0 to F9) are located on the Tech2 keypad. A function key may be pressed to initiate a specific Tech2 function. In some cases the function keys are used for numeric data entry. The arrow keys and [ENTER] may also be used to initiate a function selection, but this will require multiple keystrokes as opposed to only one.

Help Key

The help key [?] may be pressed at any time to obtain a help screen. The help screen will provide specific information relating to the operation of the Tech2.
