Displaying Fault Codes (DFC) From
SECM Memory
To enter code display mode you must turn OFF the
ignition key. Now turn ON the key but Do not start
the engine. As soon as you turn the key to the ON
position you must cycle the foot pedal by depressing
it to the floor and then fully releasing the pedal
(pedal maneuver). You must fully cycle the foot
pedal three (3) times within five (5) seconds to
enable the display codes feature of the SECM.
Simply turn the key OFF to exit display mode. The
code list will continue to repeat until the key is
turned OFF. An automatic code display feature is
activated if a foot pedal fault condition exists. This
feature enables the service technician to view the
fault codes by turning the key to the ON position, if a
foot pedal malfunction is preventing the retrieval of
the stored fault codes from the SECM.
