Hello,

Look at the joystick when the chair stops. The battery level lights should be blinking a certain number of them repeatedly. The lights are a diagnostic code. The number of the battery level lights blinking will tell you if you have a motor, joystick, module or battery problem.

Hello, If the joystick won't turn off it is a joystick problem. You can unplug the joystick cable from the joystick to save battery if you need to. This kind of problem means your joystick will need to be repaired at Invacare or replaced by a dealer of Invacare chairs.

Hello,

Seven blinks is most often the joystick. A Invacare Remote Programmer can be plugged in to the joystick to verify this.

Since time was important this may be too late.

1. You can download manuals for pretty much anything by asking Google for something like 'Pronto M41 manual'. Manuals help a lot.

2. Googling 'wheechair repair [your town]' will point you to people who can service the chair. You can also contact a local agency for people with disabilities for ideas.

The yellow wrench is a diagnostic tool. How many times does it blink between pauses. Example might be 3 blinks then pause then 3 blinks then pause, over and over. Hoe many does your chair blink?

Left parking brake has an issue. Check wiring first then measure brake resistance. Should be under 100 ohms. May also be brake release switch is faulty or brake not engaged.

Lester - so many issues. Take it to a dealer.
9-Flashes means comm fault - check joystick wiring harness.

You can download the M41 manual at the Invacare website:

First thing you must know is that the error codes are reversed on Pronto chairs with SPJ+ joysticks.
Only one year the M41 was made that the codes were correct. From approximately April 2008 to May 2009 was the only time a left error code ment left motor and a right code ment a right motor. Same for brake codes.
Brakes codes happen when the brake is out of gear, unplugged from the control brain or wire cut. Also from internal coil damage. Unless it's a wire you can reconnect you cannot fix the brake.
