Description
Cause:
In standby condition (pump motor not driven), the
feedback coming from the current sensor in the pump
chopper gives a value out of a permitted range, because
the pump current is not zero.
Troubleshooting :
This type of fault is not related to external components;
replace the controller.
This alarm occurs when the chain looser switch, read by
the traction and sent via CAN to the pump, is opened.
Cause :
A)
The motor temperature sensor is not correctly
connected to A22.
B)
The motor temperature sensor is damaged.
Troubleshooting :
A)
Check the correct connection of the motor
temperature sensor.
B)
If the current sensor is correctly connected, replace it.
C)
If the problem persist, it is due to the controller.

The main uC sends an analog signal towards the slave
uC to reset the slave uC on demand. When the slave uC
detects this analog signal external to a window from 2.2
to 2.8 and not in the range to generate the reset on
demand, the slave uC raises this alarm. It is necessary
to replace the controller.
Cause :
This warning (presents only in trucks with "Dead Man"
switch) appears when the "Dead Man" switch is open.
Troubleshooting :
At the next travel request with dead man switch close the
warning disappears.

This alarm occurs if the frequency and the amplitude of
the voltages from the stepper motor lines are
mismatched in between (i.e. the voltage from the D and
Q line of the stepper motor have high amplitude but with
very low frequency). In normal condition when the
amplitude of the stepper motor lines increases, the
frequency of the stepper motor lines must increase too.
This alarm occurs also if a stepper motor line (D or Q) is
short circuited to minus battery. Check if a stepper motor
line is short circuited to minus battery. Otherwise it is
necessary to replace the controller.
