MK6i Electronics
SPJ™+ w/PSS or SPJ+ w/ACC Joysticks
The joystick information gauge and the service indicator display 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.
