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 Tech 2 uses parts that can produce arcs or sparks. When used in a garage environment, the Tech 2 must be
located not less than 18 inches (460 mm) above the floor.

be required for individual applications.
The Tech 2 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 Tech 2. The RS-485 port is currently not used.
The Tech 2 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.
