There was no allegation of malfunction or defect made against the wheelchair.The items that required repair were the left side arm rest and the joystick.Both items were returned to sunrise medical and an evaluation was performed on 5/23/2019.The test performed on the joystick revealed a pm 7f00 fault code.This occurs when the control system detects a fault in the wiring in the communication cables between any of the modules.This fault code would be displayed to the user as an indication that service is required as an issue may need to be addressed.Depending on the severity of connection issue, the chair may still allow the user to use the wheelchair to drive and perform seating functions while this fault is being displayed.For more severe connection faults where a cable may be damaged preventing communication from passing through, the fault could prevent the chair from being operated until the issue has been identified and resolved.It is possible that the joystick was damaged during the fall, causing the 7f00 fault that is now occurring, however this fault would not have caused the chair to drive without joystick input.No further investigation will be performed by sunrise medical at this time.
