6.4 SYSTEM FAULT MESSAGES
The Help Message display on the JLG Analyzer provides diag-
nostic feedback to explain vehicle operation and interlocks.
After the Analyzer is connected to the Ground Module or Plat-
form Module, the Control System shall receives an “Initialize
Analyzer” command from the Analyzer and the Control Sys-
tem commands the Analyzer to display the top menu item:
If the operator presses ENTER when in Platform Mode and no
active faults are present, the Control System commands the
Analyzer to display:
EVERYTHING OK
If the operator presses ENTER when in Ground Mode, display
will read GROUND MODE OK.
Pressing ENTER again will cause the Analyzer to display the
current Help description followed by its’ Diagnostic Trouble
Code (DTC). Help Messages larger than the Analyzer’s display
are scrolled across the screen and repeated. Using the up
arrow will increase the scroll speed. If the Fault is active, an
asterisk will appear beside the DTC. If the operator enters
Logged Help, the Control System will show the previous 25
logged DTCs along with the Fault description on the analyzer
screen.
Table 6-4, Fault Code List lists the fault codes applicable for
this machine and the analyzer message that accompanies the
fault code. Table 6-5, Fault Code Troubleshooting Information
contains evaluation, response, display, and operational
requirements for each Fault condition.
