Diagnostic Trouble Code(s) (DTC)

Diagnostic Trouble Codes (DTCs) consist of a five-digit alphanumeric code in the for- mat shown below. When the On-Board Computer recognizes and identifies a problem in the computer-monitored systems, a DTC for that fault is stored in memory. These codes are intended to help you determine the root cause of a problem. As new DTCs are approved and added by the SAE, periodic updates to the software become available. Consult the store where the tool was purchased.

OBD II Diagnostic Link Connector (DLC)

The Data Link Connector (DLC) allows the scan tool to communicate with the vehicle computer. OBD II defines the physical and electrical specification for the DLC. Certain pins in the connector are reserved.

The DLC is also referred to as a J1962 connector, the term taken from a physical and electrical specification number assigned by SAE (Society of Automotive Engineers). The J1962 specification defines the location of

the DLC in the vehicle. The DLC should be

located under the dashboard on the driver side of the vehicle. If the DLC is not located under the dashboard as stated, a decal de-

scribing its location should be attached to the dashboard in the area the DLC should

have been located.

What the Code Scanner Does

The Code Scanner connects to the vehicle and powers-up through the DLC. Once the scanner establishes a communication link, you can then retrieve DTCs and erase data stored in the vehicle. Code Lookup provides definitions of Global (Generic) OBD II DTCs.
