This article explains how to use Innova scan tools to read and clear diagnostic trouble codes (DTCs) in Toyota/Lexus vehicles which use the OBD1 system.

The OBD1 Extension Cable & Honda Adapter are sold separately. Only the 5512 and 3170RS models come with the Adapter kit that has an OBD1 extension cable & OBD1 adapters included in a soft pouch.

Live data and all the advanced features these specific models offer only apply for OBD2 vehicles, and not OBD1 vehicles.

Procedure

To begin, it's important to understand that OBD1 is a first-generation automotive diagnostic system that was introduced in the early 1980s to help mechanics and vehicle owners identify and troubleshoot engine-related issues by providing DTCs that correspond to specific faults in the engine or emission control system. The design and capabilities of OBD1 systems vary depending on the manufacturer and model of the vehicle. Make and model also affects the shape and pin layout of the Data Link Connector (DLC).

Step 1 - Connect the Innova Scan Tool to the vehicle

• To use the Innova 5610 for reading or clearing DTCs, it's necessary to establish a connection between the tool and vehicle through the Toyota/Lexus OBD1 Adapter.

  Note: Image of the OBD1 Toyota/Lexus adapter. The left end connects to the OBD1 port of the Toyota/Lexus vehicle while the right end connects to the OBD1 extension cable which connects to the Innova 5610.

• The Innova 5610 attached with the OBD1 extension cable and Toyota/Lexus OBD1 adapter.

  Note: The OBD1 extension cable is properly connected to the 5610 and OBD1 Toyota/Lexus adapter. The other end of the Toyota/Lexus adapter isn't connected to an OBD1Toyota/Lexus vehicle due to not having one available to demonstrate.

• Select the option Read DTCs, then press the Enter ↵ button to continue.

  Wait while the Innova 5610 establishes communication with the vehicle to display the check engine codes.
