Appendix B: Fault Codes
The microprocessor checks various features within the controller and will display
any fault indication. The controller may prevent the chair from driving should a critical
fault condition exist. Refer to the appropriate fault code section for the system
used on your MPV 4.
MPV 4s using these style control systems use lighted bars to display fault
codes.
