Motor/Brake Error - Pride Q6 Edge Technical Troubleshooting Manual

3. Unplug connector 7a from connector 9b. See diagram
3 or 4.
4. Measure resistance across pin 1 and pin 2 of connector
7a. See figure 22.
— If the multimeter does not indicate about 0.5-1.5 ohms,
then go to the next step.
— If the multimeter indicates about 0.5-1.5 ohms, then go
to step 6.
5. Remove the motor brushes from the left motor (7) and
inspect them. See figure 23.
— If the motor brushes are worn below 0.25 in. or they
are physically damaged, then replace the motor
brushes and retest the system.
— If the motor brushes are not worn below 0.25 in. and
are not physically damaged, then replace the left motor
(7) and retest the system.
From step 4
6. Unplug connector 8a from connector 9d. See diagram
3 or 4.
7. Measure resistance across pin 1 and pin 2 of connector 8a. See figure 22.
— If the multimeter does not indicate about 0.5-1.5 ohms, then go to the next step.
— If the multimeter indicates about 0.5-1.5 ohms, then replace the power module (9) and retest the system.
8. Remove the motor brushes from the right motor (8) and inspect them. See figure 23.
— If the motor brushes are worn below 0.25 in. or they are physically damaged, then replace the motor brushes and
retest the system.
— If the motor brushes are not worn below 0.25 in. and are not physically damaged, then replace the right motor (8)
and retest the system.

Motor/Brake Error

Symptoms:
The batteries are fully charged.
All electrical components are connected correctly.
The power turns on, but the LCD screen displays "Motor/Brake Error" (NE or NE+ joysticks) or a brake error (Q-
Logic joystick). See table 1, 2, or 3.
Diagnosis:
There is a problem with one or both brakes and/or the wiring between the motor, brakes, and the power module (9).
Solution:
Use the following procedure to clear the error code:
1. Ensure both freewheel levers are in drive mode. Refer to the freewheel operation label located on the power base.
2. Remove the rear shroud. See figure 5.
3. Disconnect the power module (9) from the rear main frame. See figure 6.
4. Unplug connector 7a from connector 9b. See diagram 3 or 4.
