5 OBD 1 was designed to monitor manu-facturer-specific systems on vehicles builtfrom 1981 to 1995. Then came the develop-ment of OBD 2, which is on all1996 cars and light trucks sold in theUnited States. These systems are part of a government mandate tolower vehicle emissions. The sophisticated programs in the vehicle son-board computer system are designed to detect failures in a rangeof vehicle systems. Diagnostic information can be accessed through aData Link Connector test port specifically designed for this all OBD systems, if a problem is found, the computer turns on the check engine light to warn the driver, and sets a DiagnosticTrouble Code (DTC) to identify where the problem occurred.

Toavoid serious injury, always be aware of moving a safe distance from these parts as well as otherpotentially moving parts become very hot when the engine is run-ning. To prevent severe burns, avoid contact with hotengine starting an engine for testing or trouble-shoot-ing, make sure the parking brake is engaged.

9 Put thetransmission in park(for automatic transmission) orneutral(for manual transmission). Block the drivewheels with suitable or disconnecting test equipment when theignition is ONcan damage test equipment and the vehi-cle's electronic components. Turn the ignition OFFbefore connecting the Tool to or disconnecting the Toolfrom the vehicle s Data Link Connector (DLC).To avoid personal injury, instrument damage and/ordamage to your vehicle ; do not use the CAN OBD2 Toolbefore reading this & 1 ESafety PrecautionsSAFETY FIRST!To prevent damage to the on-board computer when tak-ing vehicle electrical measurements, always use a digi-tal multimeter with at least 10 megOhms of and battery vapors are highly flammable.
