INTRODUCTION

Jazzy Select Elite with GC2 or GC3 Electronics Technical Troubleshooting Guide

This Jazzy Select Elite Technical Troubleshooting Guide covers diagnostic and repair scenarios for Jazzy Select Elite

units equipped with GC2 or GC3 electronics.

This guide is divided into three sections:

Section 1—No Power

Section 2—Battery Condition Meter Scrolls - Inhibit Active

Section 3—Flash Codes

How to Use Pride Model Specific Technical Troubleshooting Guides

All new Pride ModelSpecific Technical Troubleshooting Guides follow the sameformat. They are divided into sections

addressing symptoms such as No Power. If the mobility product is capable of giving error codes, one section will deal

with each code for that model.

The troubleshooting guide utilizes diagrams that are located in the front and back of the guide. These diagrams identify

main components by number (1, 2, 3, etc.) and all connectors by number with a lower case extension (1a, 2a, 3a, etc.).

The diagrams also show how all of the components are connected.

Using the Table of Contents, locate the section that best describes your troubleshooting issue. Each section will include

a list of symptoms, followed by a diagnosis of the problem, and finally a solution or procedure to solve the problem. The

procedure is set up as a numbered list of instructions, which may include one or more tests. Results of these tests will:

Direct you to change a component and retest the system.

Go to the next numbered step.

Advance to a numbered step farther along in the section.

Figure 1. Diagram Insert

Use For Reference

System Retest

When a procedure specifies to replace a component, you

must retest the system after replacing that component.

To retest the system:

1. Replace the component.

2. Reconnect any harnesses that were disconnected.

3. Reconnect the batteries (if disconnected).

4. Power on the controller.

5. Operate the power base.

—If the power base operates normally, then reassemble

the power chair.

—If another problem has surfaced, then go to that pro-

cedure in this guide.
