Solution: Check the value of sensor and connection of
wires and the fault is inside the controller in case of no
problem found.
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”.
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.
Auxiliary
output drive
fault
Auxiliary coil drive circuit can not drive load. The
equipment or drive coil is damaged. Change the
controller.
The fault will be hinted when calibrating the current gain.
No treatment is needed and it will automatically disappear
when calibration is finished.
CAN communication fault between pump and traction.
Check CAN wiring, software setting and edition
information.
It is the time for service and maintenance is needed.
The output signal of temperature sensor of controller
exceeds the range.
The fault has nothing to do with external parts and change
the controller.
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.
Wrong selection of SLIP PROFILE PARAMETERS.
Check the setting of these values in the hardware setting
parameters.
Short circuit of the driving electric circuit of the
electromagnetic brake or auxiliary electric brake. Check if
there is short circuit between the A16 and BATT.
Circuit ault of the drive unit of the logic card; change the
controller.
