SECTION 4—SAFETY INSPECTION/TROUBLESHOOTING

About Joystick Diagnostics

The joystick information gauge and the service indicator give indications of the type of
fault or error detected by the control module. When a fault is detected, the wheelchair
may stop and not drive. The LEDs on the information gauge may flash in a particular
pattern or the service indicator light will flash. The number or type of flashes indicates the
nature of the error. If multiple errors are found, only the first error encountered by the
control module will be displayed.
