is displayed on the console.
Figure 2.26
Possible Cause
Stride motor plug issues.

Locate the controller board, either directly under the main
drive pulley (Figure 2.23) or on the right shroud mounting
tube attached to the main upright tube (Figure 2.24).

Unplug the Left (black) and Right (white) stride motor
plugs from the controller board and reverse their
positions, plugging the black plug into the white socket
and the white plug into the black socket (Figure 2.25).

Plug in the unit. After the motors stop moving (8 to 15
seconds), unplug the unit again.

Ground yourself before touching the circuit board. Unplug
the stride motor plugs from the controller board and plug
each one back into its default socket: Left (black) plug
into the black socket and Right (white) plug into the white
socket (Figure 2.26).

If the stride motor (left or right) causing the error is
unresponsive, it should be replaced following the
directions in Section III.
