Manual

This document describes the DG Technologies/DPA HEALTH™ tool. DPA HEALTH is a predictive analytic tool that accesses the current condition of the vehicle’s starting circuit, charging circuit, and battery pack.
DPA HEALTH collects the vehicle digital data using the ECU CAN message data, along with analog or digital signals from sensors and actuators. This provides a complete picture of the vehicle’s electrical system health for analysis or diagnosis of the user’s specific concerns.

Introduction

Electrical System Health Monitoring: Modern vehicles are becoming more electrified and integrated with multiple ECUs and sensors, which make them smarter in terms of engine decisions, performance, fuel efficiency, security, safety, and stability.
DPA HEALTH provides a portable diagnostic solution for your vehicle’s electrical applications. It is a predictive analytic tool that accesses the current condition of primary electrical system:
Battery / Battery pack health Starting System health Charging System health

DPA HEALTH is based on a TMC Position Paper (2018-3 “Automatic Monitoring of Electrical System Health Monitoring). The condition of the electrical system is assessed by combining circuit analysis with statistical analysis. When paired together, these two fundamentally sound sciences quantify the state of health (SOH) for batteries, alternators, starters, and electrical cables. The use of vehicle CAN communication network allows for downloading of data, scheduling of maintenance and integration with other fleet management systems.

**Recommended Usage of DPA Health

For best and accurate results**

Ambient Temperature should be above 50-degree Fahrenheit (50 ◦F). The battery pack should have a voltage of 12.0 volts or higher. On vehicles with capacitor starting systems the batteries can only be tested by isolating (disconnecting) the capacitor start system.

1. Cold weather starting aids such as battery warmers, heaters for block, fuel, oil pan and inlet air grid heaters can adversely affect the test results. Testing at temperatures above 50 ◦F is recommended.
2. Battery packs with the initial voltage below 12.0 volts will return the message “Charge and Retest”. Charge the batteries using the manufactures recommendations and allow resting time before The rest time is usually 4 hours before conducting a retest.
3. On vehicles with capacitor start systems (ultra-capacitors or super capacitors) the capacitor unit must be isolated (disconnected) before starting the test.

How DPA HEALTH Works

The application is guides the technician through a series of steps that exercises the electrical system in four phases of operation

A – Key OFF B – Key ON
C – Start Engine Cycle D – Charging Cycle

Date is recorded in each of the four phases. It takes approximately 3 minutes.

The DPA Health analysis is done in the cloud and reported back to the technician on the PC within seconds of completing the test sequence.
Features – This application is designed to work with a laptop and DG Technologies DPA XL. The following status data is displayed after hooking up to the vehicle from the DG Technologies DPA XL and opening the DPA Health Application;

DPA HEALTH Report

The state of health for each system test is color coded, Good , Marginal, Suspect.

• Good : SOH is No maintenance is required.
• Marginal : There was a problem running the test and/or missing data. Marginal is accompanied with an instruction such as Charge batteries/retest, Retest or
• Suspect Conditions warrant that maintenance should be
