7 "Rear Left Motor - Open Circuit"
Drive, Lift Up and Leveling Jack Func-
tions are Prevented.
• UGM is detecting that the Left Power Module is communi-
cating that the Left Drive Motor Phase Voltage value is read-
ing as an open circuit.
• Check the Drive Motor Phase Voltage cable connections W, U
and V are properly connected at the drive motor. Check the
cable connections at the module terminals. Check the cables
for continuity or damage.

7 "Rear Right Motor - Open Circuit"
Drive, Lift Up and Leveling Jack Func-
tions are Prevented.
• UGM is detecting that the Right Power Module is communi-
cating that the Right Drive Motor Phase Voltage value is
reading as an open circuit.
• Check the Drive Motor Phase Voltage cable connections W, U
and V are properly connected at the drive motor. Check the
cable connections at the module terminals. Check the cables
for continuity or damage.
