SECTION 5 - CONTROL COMPONENTS
3121222
– JLG Lift –
5-11
10. CANBUS FAILURE: POWER MODULE (6-6)
a.
The control system failed to receive mes-
sages from the Power Module. Check wiring
at the Ground Control Box and Power Mod-
ule. Recycle power to clear difficulty.
b.
May indicate harness difficulty or a faulty
Power Module.
c.
Resistance between CANH (Power Module
Pin 10) and CANL (Power Module Pin 11)
should be 60 ohms (+/- 5%) with the Power
Module connected.
d.
Resistance between Power Module Pins 10
and 11 (harness disconnected) should be
120 ohms (+/- 5%).
e.
10 Flashes on Power Module.
f.
Drive, Steer, & Lift Up Prevented.
11. OPEN-CIRCUIT DRIVE MOTOR WIRING (7-7)
a.
The Power Module detected an error in the
Power Wiring (M1, M2, F1 & F2 Terminals) for
the Drive Motors. Check power wiring and
re-cycle power to clear difficulty. Alter-
nately, there may be an issue (open field,
armature, or brush) with one of the Drive
Motors.
b.
May indicate field wiring or winding issues.
c.
5 Flashes on Power Module.
d.
Drive & Steer Prevented.
12. POWER MODULE FAILURE: PERSONALITY
RANGE ERROR (9-9)
a.
The Power Module detected an out-of-
range or corrupt personality setting.
b.
Enter Access Level 1 on the JLG Analyzer, re-
select Model, and cycle EMS after 5 seconds.
May indicate a Power Module issue if it can-
not be reset.
c.
1 Flash on Power Module.
13. POWER MODULE FAILURE: INTERNAL ERROR
(9-9)
a.
The Power Module detected an internal
error via self-test.
b.
May indicate that the Line Contactor Coil is
Open-Circuit in Power Module's prior to
V1.10, a Power Wiring Issue, or a faulty
Power Module.
c.
11 Flashes on Power Module.
14. POWER MODULE FAILURE: CHECK POWER
CIRCUITS OR MOSFET SHORT CIRCUIT (9-9)
a.
The Power Module detected an error in the
Power Wiring for the Drive or Pump. Alter-
nately, the Power Module has failed a self-
test.
b.
3 Flashes on Power Module may indicate a
Short-Circuit in the Armature Wiring or a
faulty Power Module.
c.
No Flashes on Power Module may indicate a
faulty Power Module.
