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.
