My ICON wheelchair with a SmartDrive MX2, which has been modified to the MX2+ configuration, was secured in my van when I evidently made a couple of sharp movements of my right hand. I heard the SmartDrive engage for about 3 second and then stop before I had a chance to deactivate it with a double tap. I turned the Push Tracker off.

When I arrived home, I turned off the SD, waited a minute or so and turned both the SD and PT back on and got a blue indicator light from the PT and four blue lights from the SD - no error codes but it does not engage. When I back up, I can feel resistance from the SD, but none when pushing forward. I was hoping that there was a reset, but none obvious

Any thoughts?
