Code
61 Actuators not reaching lightoff point.
65 Internal Memory fault.
66 Internal Initialization Error.
67 Fuel Actuator off curve (selected fuel type).
68 FGR Actuator off curve.
69 Air Actuator off curve.
71 Verifies that the Air actuator accepted the off-line, on-
line, move counterclockwise and move clockwise
commands. Furthermore, all potentiometer tests
must successfully passed to bring an actuator online.
72 Verifies that the Fuel 1 actuator accepted the off-line,
on-line, move counterclockwise and move clockwise
commands. Furthermore, all potentiometer tests
must successfully passed to bring an actuator online.
73 Verifies that the Fuel 2 actuator accepted the off-line,
on-line, move counterclockwise and move clockwise
commands. Furthermore, all potentiometer tests
must successfully passed to bring an actuator online.
74 Verifies that the FGR actuator accepted the off-line,
online, move counterclockwise and move clockwise
commands. Furthermore, all potentiometer tests
must successfully passed to bring an actuator online.
75 Internal memory fault.
76 Internal check sum error.
82 Actuator secondary fault.
83 Air actuator non-responsive.
84 Fuel 1 actuator non-responsive.
85 Fuel 2 actuator non-responsive.
86 FGR actuator non-responsive.
87 Internal math error.

Description Corrective Action
Check for actuator wiring problems or stuck valves/dampers.
Place controller in standby and use actuator manual keys to
verify actuator travel.

Reset control . Check the wiring and range capability for both the
CmA+- input and XmA+- input (if configured).
Check for stuck fuel actuator and/or proper shielding on actuator
interface.
Check for stuck FGR actuator and/or proper shielding on
actuator interface.
Check for stuck Air actuator and/or proper shielding on actuator
interface.
Check wiring of actuator, verify correct ID is being used. Use
Actuator LED to verify that the actuator that is being brought
"online". A fast flash in the actuator equates to "off line" state
while a 1 second flash equates to an "online" state.
