DIAGNOSTICS CODES
The joystick battery discharge indicator and the Remote Programmer give indications of
the type of fault or error detected by the control module. When a fault is detected, the
chair will stop and not drive. For the SPJ-80 joysticks, the last two red bars of the BDI
will begin to flash followed by a pause. An error code and a quick description of the
fault will begin to scroll across the Remote Programmer display. If multiple faults are
found, only the first fault encountered by the control module program will be displayed.
Refer to the Power Chair Service Manual for detailed trouble shooting and repair
instructions. Below is a list of the diagnostics codes and their causes:
