Description
Short circuit of the pump speed
sensor to battery positive.
Short circuit of the pump speed
sensor to battery negative or open
circuit.
Short circuit of the accumulator
pressure switch to battery positive.
Short circuit of the accumulator
pressure switch to battery negative.
Right rear drive controller, thermal
protection senses that temperature
has exceeded 185° F / 85° C.
Left rear drive controller, thermal
protection senses that temperature
has exceeded 185° F / 85° C.
Return signal from the right rear drive
motor encoder to the right rear drive
controller is 40 Hz or higher.
Return signal from the left rear drive
motor encoder to the left rear drive
controller is 40 Hz or higher.
Right rear drive motors rotor is stuck
or the return signal from the encoder
is incorrect.
Left rear drive motors rotor is stuck or
the return signal from the encoder is
incorrect.
Open circuit of the right rear drive
motor thermal sensor to right rear
drive controller (D3) or faulty thermal
sensor.
Open circuit of the left rear drive
motor thermal sensor to left rear
drive controller (D3) or faulty thermal
sensor.
Steer angle sensor out of range.
