I have invacare pronto m51 with surestep the spjis flashing 9 times what is the problem

The 9 flash error code indicates a communications fault. The communication fault relates to the communication between the joystick and the control module. The joystick on the arm mount is connected to the control module in the base. When there is a break in the wiring of this wiring harness, also called a bus cable, a fault occurs. This trips the computer and the computer sends out a flash code to the joystick. Simply stated there is a broken or pinched wire between the joystick and controller. Look physically at the wire and check for cuts, breaks or pinches. The best short term repair is to repair the broken wire with solder and heat shrink or tape. You can also use **** splice connectors and tape. The best long term repair is to replace the harness with a part available from Invacare. The most definitive way to diagnose this problem is to read the fault log of the controller using a hand held programmer available to dealers and certified technicians. The number and type of fault codes logged in the controller is another indicator of which
component(s) has failed. Hope this helps.
