Section 10 - Diagnostic Trouble Codes; Introduction; Dtc Index - JLG TOUCAN 10E Service And Maintenance Manual

10.1 INTRODUCTION

This section provides a reference for Diagnostic Trouble
Codes (DTC) read from the analyzer. DTCs are also dis-
played on the Multi Display Indicator (MDI, Ground Con-
sole) and on the face of the platform console. For more
information on any sensors or indicators, refer to the
appropriate section for the machine area. Many of the
checks below require configuring and using a multimeter.
Refer to Section 11, GENERAL ELECTRICAL INFORMA-
TION & SCHEMATICS for multimeter basics. DTCs are
sorted in groups by the first two digits, which are also the
system distress lamp flash code. To troubleshoot multiple
DTCs, start with the DTC with the higher first two digits. To
view all active DTCs on the analyzer, view logged help
before the first power cycle. The machine is powered by a
nominal 24 Volts battery pack.
Some procedures below refer to this nominal voltage as
24V. Actual voltage measurements may differ based on
the charge of the batteries. If a correction is made dur-
ing a check, conclude the check by cycling the
machine power, using the emergency stop switch. It
may also be helpful to run a system test, ANALYZER ->
SYSTEM TEST for intermittent or difficult problems.
