4 “Battery Voltage too Low - System Shut
Down”
All UGM Valve Outputs are turned off. • UGM detects the Machine's System Voltage is less than 9V.
442
4
4 “Battery Voltage too High - System Shut
Down”
All Machine Functions are Pre-
vented.
• UGM detects the Machine's System Voltage is greater than
16V.
443
4
4 "LSS Battery Voltage High"
No Response.
• The LSS Supply Voltage is Greater than 34V.
• Check battery supply and wiring to the LSS Control Module.
444
4
4 “LSS Battery Voltage Low”
No Response.
• The LSS Supply Voltage is Less than 9V.
• Check battery supply and wiring to the LSS Control Module.
46163 4
6 "Hyd Fluid Temp Sensor - Out Of Range
High"
No Response.
• UGM is detecting the Hydraulic Fluid Temp Sensor is Higher
than 4.75V.
• Check sensor for damage or faulty wiring.
46164 4
6 "Hyd Fluid Temp Sensor - Out Of Range
Low"
No Response.
• UGM is detecting the Hydraulic Fluid Temp Sensor is Higher
than 0.25V.
• Check sensor for damage or faulty wiring.
4646

6 "Parking Brake Valve - Short To Battery"
All Machine Functions are Pre-
vented.
• UGM Detects that the Parking Brake Valve (J2-1) is reading a
Short to Battery Circuit.
4647
4
6 "Parking Brake Valve - Short To Ground"
No Response.
• UGM Detects that the Parking Brake Valve (J2-1) is reading a
Short to Ground Circuit.
4648
4
6 "Parking Brake Valve - Open Circuit"
No Response.
• UGM Detects that the Rear Right OSC Axle Extend Valve (J2-
1) is reading as an Open Circuit.

6 “CANBUS Failure - Platform Module”
Machine Functions from Platform
are Prevented.
• UGM is detecting that CAN Communication has been lost
with the Platform Module.
• Check platform connector and connections under the deck
for damage and faulty wiring. Check for 12V on PWR and
GND wires with machine powered on. Measure between the
CAN wires for 60 ohms, if not then CAN wires/circuit have
damage. If above checks out okay, then Display may need
replaced.
663
6
6 “LSS Not Sending CAN Messages”
Machine Behaving as if it is Over-
loaded.
• UGM is detecting that CAN Communication has been lost
with the LSS Module.
• Check LSS module connector and connections under the
deck for damage and faulty wiring. Check for 12V on PWR
and GND wires with machine powered on. Measure between
the CAN wires for 60 ohms, if not then CAN wires/circuit have
damage. If above checks out okay, then Module may need
replaced.
6635
6
6 “CANBUS Failure - Chassis Tilt Sensor”
Lift Up is Prevented and Drive is
allowed in Torque Speed when the
Platform is Stowed. Chassis Tilt Cali-
bration Prevented.
• UGM is detecting that CAN Communication has been lost
with the Chassis Tilt Sensor.
• Check Tilt sensor connector for damage and faulty wiring.
Check for 12V on PWR and GND wires with machine powered
on. Measure between the CAN wires for 60 ohms, if not then
CAN wires/circuit have damage. If above checks out okay,
then Tilt Sensor may need replaced.
6650
6
6 “CANBUS Failure - Oscillating Axle Tilt
Sensor”
Lift Up is Prevented and Drive is
allowed when the Platform is
Stowed. Front Axle Tilt Sensor Cali-
bration Prevented.
• UGM is detecting that CAN Communication has been lost
with the Front Axle Tilt Sensor.
• Check Tilt sensor connector for damage and faulty wiring.
Check for 12V on PWR and GND wires with machine powered
on. Measure between the CAN wires for 60 ohms, if not then
CAN wires/circuit have damage. If above checks out okay,
then Tilt Sensor may need replaced.
