Diagnostic codes are standardized alphanumeric codes used to classify and describe medical diagnoses and procedures. The most widely used systems are the International Classification of Diseases (ICD) codes, which are updated periodically, and Current Procedural Terminology (CPT) codes for procedures. ICD codes typically consist of a letter followed by numeric digits (e.g., A00.0), while CPT codes are usually five-digit numeric codes (e.g., 99213). These codes facilitate communication among healthcare providers, insurers, and researchers regarding patient care and billing.

Diagnostic Trouble Codes.
To pull diagnostic trouble codes (DTCs) from a 1995 Infiniti J30, first locate the diagnostic connector under the driver's side dashboard. Use a jumper wire to connect terminals "E" and "T" on the connector. Turn the ignition key to the "ON" position (without starting the engine), and the check engine light will begin to flash, indicating the codes. Count the flashes to identify the codes, which will be in a two-digit format.

Diagnostic codes are generated by your on-board computer. They tell you what problems the computer has identified with your engine. The codes are numbers. The code numbers are read by an instrument that plugs into a special jack under the dash. Auto parts stores often will check your diagnostic codes for free, or you can have your dealer do it.
