INTRODUCTION
J6 with NE, NE+, and Q-Logic Electronics Technical Troubleshooting Guide
This J6 Technical Troubleshooting Guide covers diagnostic and repair scenarios for J6 units equipped with NE, NE+,
and Q-Logic electronics.
This guide is divided into three sections:
Section 1—No Power
Section 2—Power Chair Will Not Drive Due to System Lock
Section 3—Error Code Diagnostics
How to Use Pride Model Specific Technical Troubleshooting Guides
All new Pride ModelSpecificTechnicalTroubleshooting 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.
NOTE: Printed versions of Pride Technical Troubleshooting Guides include diagram inserts that can be used for refer-
ence while troubleshooting the mobility device. See figure 1
