Innova SD35 SD-Advisor: Battery Test

Purpose

To guide you on how to check the battery status using the Innova SD35 SD-Advisor Tablet Scan Tool.

Introduction

The battery is a crucial component in a vehicle's electrical system, as it provides power for starting the vehicle and supporting systems like the headlights and air conditioner fan while the engine is not running. The Battery Test feature allows us to assess the battery status, which can give us an idea of its performance in the future.
