SECTION 10 - DIAGNOSTIC TROUBLE CODES
• Check for Ground and Platform Emergency Stop
connections
• If the fault appears at start up or during standby :
check that no external device is connected to the
batteries, creating down-going pulses. Refer to a
qualified JLG mechanic to know the approved
options on the machine.
• If no voltage transient is detected on the supply line
and the fault appears every time the key is switched
ON : Replace the Master controller.
• Check if the fault appears during traction accelera-
tion or driving hydraulic functions (undervoltage
condition detected) : check battery charge; check
for damaged batteries, battery cables and connec-
tions
• Check if the fault appears during traction braking
(overvoltage condition detected) : check line con-
tactor contact, battery power cable connection.
• Check for Ground and Platform Emergency Stop
connections
• If the fault appears at start up or during standby :
check that no external device is connected to the
batteries, creating down-going pulses. Refer to a
qualified JLG mechanic to know the approved
options on the machine.
• If no voltage transient is detected on the supply line
and the fault appears every time the key is switched
ON : Replace the Slave controller.
• Check if the fault appears during traction accelera-
tion or driving hydraulic functions (undervoltage
condition detected) : check battery charge; check
for damaged batteries, battery cables and connec-
tions
• Check if the fault appears during traction braking
(overvoltage condition detected) : check line con-
tactor contact, battery power cable connection.
• Recharge batteries.
• Check for damaged batteries, battery cables or
connections.
• Check battery charger function. Be sure to observe
indicators for at least 30 seconds.
• Check the right motor encoder wiring and connec-
tions.
• Check the harness for proper installation (refer to
Section 11).
• Check the left motor encoder wiring and connec-
tions.
• Check the harness for proper installation (refer to
Section 11).
