OBD1 Diagnostic Cables & Adapters

Before the universal SAE J1962 OBD2 standard, manufacturers used OBD1 connectors, each with unique pin layouts and communication protocols. Servicing these vehicles requires the correct OBD1 diagnostic cable or adapter, allowing modern scanners to interface with older systems.

At AZscanners Australia, we supply professional OBD1 adapters designed for workshops, fleets, and auto electricians who maintain pre-1996 vehicles. These adapters enable stable ECU communication for:

  • Engine diagnostics – read and clear manufacturer-specific fault codes.
  • ABS & transmission access – depending on the make and model.
  • Brand-specific protocols – Toyota, Holden, Ford, BMW, Nissan, and more.
  • Workshop-ready durability – built to withstand daily professional use.

Our range ensures you can connect OBD2 scanners to vehicles using ALDL, proprietary 12-pin, 14-pin, and other OBD1 connectors, with accurate communication and long-lasting performance.
