BRAKE RUN
OUT
The CPOT BRAKE input read
by the microcontroller is at its
maximum value without the hand-
brake request.
Check the mechanical calibration
and the functionality of the brake
potentiometer. If the alarm is still
present, replace the logic board.

Reload HM from
MDI
The hour-meter of the controller is
transferred and recorded on the
hour-meter of the standard MDI.
65
MOTOR
TEMPERAT.
This warning occurs when the
temperature sensor is open (if
digital) or if it has overtaken the
MAX MOTOR TEMP threshold (if
analog).
- Check the temperature read
by the thermal sensor inside
the motor through the MOTOR
TEMPERATURE reading in the
TESTER function.
- Check the sensor ohmic value
and the sensor wiring.
- If the sensor is OK, improve the
cooling of the motor.
- If the warning is present when
the motor is cool, replace the
controller.
178
MOTOR TEMP.
STOP
The temperature sensor has
overtaken the STOP MOTOR
TEMP. threshold
- Check the temperature read
by the thermal sensor inside
the motor through the MOTOR
TEMPERATURE reading in the
TESTER function.
- Check the sensor ohmic value
and the sensor wiring.
- If the sensor is OK, improve the
cooling of the motor.
- If the warning is present when
the motor is cool, replace the
controller.
218
SENS MOT
TEMP
KO
The output of the motor thermal
sensor is out of range.
- Check if the resistance of
the sensor is what expected
measuring its resistance.
- Check the wiring.
- If the problem is not solved,
replace the logic board.

EPS RELAY
OPEN
The controller receives from
EPS information about the safety
contacts being open.
Verify the EPS functionality.
