1. Scope and Use of This Manual
…provide the reader with enough background information to understand the overall operation of the maxAI 430iv…
The intent of this manual is to provide the reader with all of the information required to install and
troubleshoot the maxAI 430iv display, as well as to provide background information regarding the overall
operation of a data-bus. Additional data-bus information not covered in this manual is available from the
SAE.
The user is expected to have a basic knowledge of the vehicle’s electrical wiring, circuits, and schematics
as well as operating parameters normally displayed on an instrument cluster, such as engine RPM, vehicle
speed, engine temperature, transmission temperature, engine oil pressure, transmission oil pressure, etc.
