Troubleshooting guidance
Restart equipment or replace ECU
Check the connection between communication lines and
other cables. If the fault still cannot be eliminated, please
replace the PCU or ECU.
Enter the parameter adjustment menu and modify the
machine parameters.
Check whether the CAN bus is in poor contact or replace
the lithium battery
Release the foot switch. If it is invalid, check the connection
status of the pedal harness (for short circuit, etc.)
The alarm can be cancelled by lowering
Recalibrate the upper limit or the outdoor limit
Check whether the chassis lift or lower button is pressed at
power-up, or replace the ECU
Check CAN bus for poor contact or modify electric drive
type
Check CAN bus for poor contact or modify electric drive
type
Check whether the CAN bus is in poor contact or replace
the lithium battery
Pothole protection error: check whether the pothole
protection is enabled and check the pothole protection limit
switch. Check the lower limit switch and wiring.
This reminder can be canceled in case of drop
Check or replace the lowering proportional valve
Check the sensor wiring and the sensor itself, and check
whether the sensor is not installed but the weighing function
is turned on.
Check the sensor wiring and the sensor itself, and check
whether the sensor is not installed but the weighing function
is turned on.
Calibrate the light load, or turn off the double load function.
This fault is only saved and not displayed. It is used to
remind the operator.
Re-calibrate no load and full load
If battery power is low, charge it in time; If the battery
power is normal, check the wiring or replace the ECU.
Conduct re-calibration
Check CAN bus for poor contact or replace GPS equipment
Unlock or connect GPS equipment
Make sure nothing presses the key on the handle. If so,
consider replacing the handle or PCU.
