CHECKSUM Memory fault in flash memory and the fault signal is produced in case of
negative value.
Fault analysis: The problem is on flash memory of
microcontroller. The flash memory may be damaged or
the program stored destroyed. Try to reset the program of
logic card. The fault exists in the microcontroller if the
fault still exists, Change the controller.
242
ENCODER
LOCKED
Feedback
signal fault of
encoder
Under normal condition
，
if the target speed is greater
than10 Hz and the rotation speed of motor higher than 1.5
Hz, the feedback signal of encoder checked by controller
should exceed a threshold value. If not, the controller will
give alarm. Test the motor encoder and see if motor or
wiring is normal and if installation correct. Change the
controller if periphery is normal.
243
SENS MOT
TEMP KO
Fault of
temperature
sensor
Phenomenon
：
The output signal of temperature sensor of
motor exceeds the scope.
Solution: Check the value of sensor and connection of
wires and the fault is inside the controller in case of no
problem found.
244
SOFTWARE
ERROR
Software error
During software testing, there are many reasons for such
fault such as: CAN communication fault and EEPROM
READ/WRITE ERROR etc. Check the parameter of
“DEBUG MODE”, the value must be “OFF”.
245
WRONG RAM
MEMORY
Dynamic
memory fault
Wrong contents are found when testing the main memory:
The registration address is “DIRTY” and the fault will
restrict the operability of vehicle.
Fault analysis: Switch on the key after switching it off and
change the controller if the trouble still exists.
247
DATA
ACQUISITION
Data
acquisition
The fault will be hinted when calibrating the current gain.
No treatment is needed and it will automatically disappear
when calibration is finished.
248
NO CAN
MESSAGE
NO CAN
signal
CAN communication fault between pump and traction.
Check CAN wiring, software setting and edition
information.
249
CHECK UP
NEED
Service time
It is the time for service and maintenance is needed.
250
THERMIC
SENS KO
Temperature
sensor fault
The output signal of temperature sensor of controller
exceeds the range.
The fault has nothing to do with external parts and change
the controller.
251
WRONG SET
BATTERY
Wrong set of
battery
During startup, the controller tests if the voltage of battery
is within the nominal scope. Check if the value of
BATTERY VOLTAGE parameter in the menu conforms to
that on the voltmeter. If not, make them conform to each
other with the function of ADJUST BATTERY.
Change the battery.
253 SLIP PROFILE Slip fault
Wrong selection of SLIP PROFILE PARAMETERS.
Check the setting of these values in the hardware setting
parameters.
