662 6 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.
6651 6 6 “CANBUS Failure - Ground Display” No response. • UGM is detecting that CAN Communication has been lost
with the Ground Display.
• Check ground display connector for damage and faulty wir-
ing. 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.
6654 6 6 "Canbus Failure - Rear Left Module" Drive, Lift Up and Leveling Jack Func-
tions are Prevented. • UGM is detecting that CAN Communication has been lost
with the Left Power Module.
• Check CAN2 buss connections on machine. Check MS434 and
module connector CO371-J1 pins 27 and 28.
6655 6 6 "Canbus Failure - Rear Right Module" Drive, Lift Up and Leveling Jack Func-
tions are Prevented. • UGM is detecting that CAN Communication has been lost
with the Left Power Module.
• Check CAN2 bus connections on machine. Check MS434 and
module connector CO342-J1 pins 27 and 28.
6661 6 6 “CANBUS Failure - Arm Stack Tilt Sensor” Lift Up Prevented. • UGM is detecting that CAN Communication has been lost
with the Arm Stack 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.
