INTRODUCTION
Q6 Edge with NE, NE+, and Q-Logic Electronics Technical Troubleshooting Guide
This Q6 Edge Technical Troubleshooting Guide covers diagnostic and repair scenarios for Q6 Edge units equipped with
NE, NE+, or 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
.

The NE or NE+ joystick (1) has an LCD screen. See figure 14 . The charging and lights indicators are lit steadily when
the corresponding function is active. When these indicators are flashing, they indicate the location of a problem. When
encountering warning or error indicators on the LCD screen, more information can be found by connecting a Curtis
Handheld Programmer and checking errors in the Diagnostics section of the programmer. If the error is happening as you
check with the programmer, then the information can be found under Actual Faults in the Diagnostics section of the
programmer.
See figure 15 . If the error occurred previously but is not currently displayed, then the information can be
found under Fault History in the Diagnostics section of the programmer.
See figure 16 . For any warning or error indicator
not noted in this technical troubleshooting guide, contact Quantum Technical Service for further troubleshooting.

Battery Charging or Drive Inhibit
Symptoms:
The power chair powers on, but will not drive.
The off-board charger is not plugged into the NE, NE+, or
Q-Logic joystick (1).
The LCD screen on the NE or NE+ joystick (1) displays
“Battery Charging or Drive Inhibit Error” when the on/off
key is released.
The battery condition meter LEDs on the Q-Logic joystick
(1) scroll when the on/off mode select lever is deflected and
“Charger Inhibit Error #107” is displayed. See figure 13.
Diagnosis:
There is an open in the inhibit circuit.
Solution:
Use the following procedure to find the source of the error:
NOTE: If the power chair is not equipped with a PTO harness
and a round 4-pin barrel connector, it will have a 14-pin run
plug (10) in connector 9e. If the power chair is equipped with
the 14-pin run plug, go to step 3.
1. Unplug the run plug (12) from connector 11b. See diagram
1 or 2.
2. Place a jumper from pin 3 to pin 4 on connector 11b. See
figure 17. Try to drive the chair.
WARNING! Jumping pins 1 and 2 could
cause sparking and/or cause the fuse in
the harness to blow.
— If the power chair drives, then replace the run plug (12) and
retest the system.
— If the power chair does not drive, then go to the next step.
3. Unplug connector 11a, or the 14-pin run plug (10) if
equipped, from connector 9e. See diagram 3 or 4.
4. If the power chair is equipped with NE electronics, place a
jumper from pin 4 to pin 6 on connector 9e. See figure 18.
If the power chair is equipped with NE+ or Q-Logic
electronics, place a jumper from pin 1 to pin 9 on connector
9e. See figure 19. Try to drive the chair.
WARNING! Jumping the incorrect pins
could cause sparking and/or damage to
the electronics.
— If the power chair drives and there is a seating system plugged
into connector 11b,
then replace the power take-off (PTO)/
inhibit harness (11) or the 14-pin run plug (10) and retest the
system.
— If the power chair does not drive, then go to the next step.

5. Verify the inhibit program. For NE electronics, inthe charger inhibit (i2) program, “chrgInb” should be set to “ON.”
See figure 20. For NE+ or Q-Logic electronics, the inhibit program should be set to “High.” See figure 21.
— If the inhibit is programmed incorrectly, then reprogram the inhibit and retest the system.
— If the power chair does not drive and the inhibit program is correct, then replace the power module (9) and retest
the system.
