SECTION 9—DIAGNOSTIC CODES
What Are Diagnostics Codes?
The joystick information gauge and the Remote Programmer give indications of the type
of fault or error detected by the control module. When a fault is detected, the wheelchair
will stop and not drive. All of the lights on the information gauge will begin to flash (SPJ
and CSPJ joysticks) or the service indicator light will flash (SPJ+ and SPJ+ w/ACC
joystick). The number of flashes indicates the nature of an abnormal condition. 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 Wheelchair Service
Manual for detailed troubleshooting and repair instructions. A table of the diagnostics
codes and their causes follows.
*NOTE: The fault log displays a four digit number. The first two digits are the diagnostic code and
the remaining two digits are the sub code.
