Understanding the 1987 300zx Diagnostic System

The 1987 300zx predates the standardized OBD-II system, which became mandatory in 1996. This means it doesn’t have a standard 16-pin OBD2 port.

These codes are represented by a combination of letters and numbers and correspond to specific issues within the vehicle’s systems. Consult a 1987 Nissan 300zx service manual or an online database for accurate code definitions.
