4.13 DIAGNOSTIC TROUBLE CODES (DTC)
Introduction
This sub-section provides a reference for Diagnostic Trouble Codes (DTC) read from the Multifunction Digital Indicator (MDI). For
more information on the MDI, refer to Section 3. For information on the locations of any limit switches/sensors, refer to Section 2.
DTCs are sorted in groups by the first two digits, which is also the system distress lamp flash code. To troubleshoot multiple DTCs,
start with the DTC with the higher first two digits. If a correction is made during a check, conclude the check by cycling the
machine power, using the emergency stop switch.
