5.9 DIAGNOSTIC TROUBLE CODES (DTC)
The DTC tables following are sorted in groups by the first two digits,
these digits represent the number of flashes the system distress indica-
tor lamp will flash on the platform indicator panel when a fault occurs.
For example: a “2-1 Power-Up” on page 19 would be indicated by 2
flashes, a pause, then 1 flash, a pause, then would keep repeating until
the fault is cleared.
The more detailed three digit code numbers in the DTC column of the
following tables are only indicated on a JLG handheld diagnostic ana-
lyzer.
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 off then back on, using the
emergency stop switch.
NOTICE
SHOULD A FAULT OCCUR WHICH CANNOT BE CORRECTED BY THE OPERATOR,
THE PROBLEM MUST BE REFERRED TO A MECHANIC QUALIFIED TO REPAIR
