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 indicator 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 analyzer.
To troubleshoot multiple DTCs, start with the DTC with the
higher first two digits. I
f 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
