Issue
"Err2" (left) or "Err3" (right)
is displayed on the console.
Q45 2.3
Possible Cause
Faulty communications
chip on controller board.
Faulty controller board.
Faulty stride motor.
Faulty power supply.

Unplug the unit. Remove the Q45/Q45e/Q45ce controller
board from the frame. The controller board is located
directly under the main drive pulley (Figure 2.278) or
on the right shroud mounting tube attached to the main
upright tube (Figure 2.28).

Ground yourself before touching the circuit board. Use
a chip puller to gently remove the old IC chip (PD-21-
SD45-XX), shown in Figure 2.29.

Be sure the new chip is facing the same direction as the
old one. Note the orientation of the stamped "half moon"
marking on the black plastic portion of the chip. Align the
pins of the new IC chip (PD-21-SD45-03) with the socket
and gently press it into place, taking care not to bend the
pins.

Plug in the unit. Verify that the "Err2" or "Err3" is no
longer appearing on the console. If the issue is resolved,
reattach the controller board to its position on the frame.
Note: If "Err11" is displayed, or if all the LEDs are lit, the
new chip is seated in its socket upside down, and you will
need to remove it and reinsert it in the socket correctly.

If the stride motor (left or right) causing the error moves
up one turn upon reset instead of returning down to the
default position, the controller board must be replaced
following the directions in Section III.

Determine the version number of the controller board by
looking at the last two digits of the serial number: Version
2 ends in "SD45-X2" and Version 3 ends in "SD45-_ _".
(Figure 2.29).

If the controller board is not Version 3, and the steps
on the previous page have failed to resolve the error
condition, you will need to replace the controller board
according to the directions in Section III.

If a motor is completely unresponsive when you reverse
the plug-ins as described on the previous page, you will
need to replace the adjustable link assembly according to
the directions in Section III.

If the console flickers or is dimming just prior to the "Err2"
or "Err3", replace the power supply and test.
