They mean
forward pedal potentiometer is out of range
valve output is out of range due to open or short
Rear pedal potentiometer is out of range.
To have all of these I would guess the wires got pulled out of the connectors. Look under the pedals on the right floorboard and see if there is any debris that pulled loose the wires from the connectors. It may not be easily noticable, unplug the connectors and press the wires back into the connector. Check the fuses to see if any are blown. Look for any chaffed wires. Basically do a real close look at the wiring on the right side under the floor from the firewall to the rear end.

thank you for reply
I want to calibrate it and I don't understand what did they mean by range in A and footdeck must be fully installed???
Problem or Situation:
Follow the procedure below.
Solution:
Do Not Calibrate the complete system if it is not needed. The only time the complete system needs to be calibrated is when the: Proportional Valve, Proportional Valve Coil, Drive Controller or complete Hydrostatic transmission has been changed Note: The system will not calibrate if the system has a problem.
Tractor Set-up
- Key in "off" position
- Tractor on jack stands.
- Range in A
- MFWD "off"
- Check that rear wheels can spin freely (no brake drag etc.)
- The Footdeck must be fully installed
- Verify engine idle is set at 950 (+or? 25RPM
- Verify engine full throttle is 2810 (+or ? 25RPM
Procedure: Enter calibration mode
1. Move fuse from F9 to F10 54179_1.jpg position. (If the original position of the calibration fuse is in the F9 position) Move fuse from F11 to F12 54179_3.jpg position (If the original position of the calibration fuse is in the F11 position)
2. Start tractor and firmly adjust the throttle lever to the idle position with the operator on seat.
3. Fault light should be on solid.
If on: Go to step 4
If not on:
Verify that the correct fuse has been moved per the steps above.
Test the wiring circuit from the drive controller to the indicator light.
Test the power and ground circuit to the drive controller.
4. Move fuse from F10 to F9 or F12 to F11 position (See links @ step 1).
Calibrate forward pedal potentiometer
5. Fault light will display (.-..) only, wait 5 seconds. If the light remains solid post moving the fuse test the following: Test the frequency of the engine speed sensor per the technical manual. Refer to DTAC solution 61940 if the unit does not have an engine speed sensor and reference DTAC solution 57661.
Isolate and test the wiring (ohms & continuity) from the engine speed sensor or alternator to the drive controller connector.
6. Fully depress forward pedal; hold for 5 seconds then release pedal.
7. Fault light should display (--..) only
If so: Go to step 8
If not test the following:
A. The forward pedal potentiometers voltage range is not within specifications (See DTAC solution 55289).
B. Isolate and test the wiring (ohms & continuity) from the forward pedal potentiometer to the drive controller connector.
Calibrate reverse pedal potentiometer
8. Fully depress reverse pedal; hold for 5 seconds then release pedal.
9. Fault light should display (?) only
If so: Go to step 10
If not test the following:
A. The reverse pedal potentiometers voltage range is not within specifications (See DTAC solution 55289).
B. Isolate and test the wiring (ohms & continuity) from the reverse pedal potentiometer to the drive controller connector.
Calibrate throttle potentiometer
10. Move throttle lever to full throttle and wait 5 seconds. Leave lever at full throttle for the remainder of the procedure.
11. Fault light should display (. - - -) only
If so: Go to step 12
If not test the following:
A. The throttle lever potentiometers voltage range is not within specifications (See DTAC solution 55289).
B. Isolate and test the wiring (ohms & continuity) from the throttle lever potentiometer to the drive controller connector.
C. Review DTAC solution 59600.
Calibrate forward proportional valve threshold
12. Fully depress forward pedal until rear wheel moves slightly and stops.
A. If after 25 seconds there has been no wheel movement, check the following:
Isolate and test the wiring (ohms & continuity) from the forward proportional valve to the drive controller connector.
Verify 12 VDC at the X25 connecter wire number 539 white with the operator on the seat.
Hydraulic charge pressure to hydro per the technical manual.
B. If after 25 seconds the wheels continue to rotate, check the following:
Isolate and test the wiring (ohms & continuity) from the MFWD speed sensor to the drive controller connector.
Replace the (LVU11184) MFWD speed sensor as required. See DTAC solution 57661.
13. Release pedal.
14. Fault light should display (. - - -) only.
Calibrate reverse proportional valve threshold
15. Fully depress reverse pedal until rear wheel moves slightly. If after 25 seconds there has been no wheel movement, check the following:
Isolate and test the wiring (ohms & continuity) from the reverse proportional valve to the drive controller connector.
Test the resistance of the reverse proportional valve coil per the technical manual.
16. Release pedal.
17. No fault light should be displayed.
If so end of procedure.
If not: verify Tractor Set-up and repeat the procedure once more

You have a range lever on the left side of the machine A-B-C. It must be in A-Range for the procedure. I assume footdeck is the platform where your feet go, I guess it has to be there to properly support the pedals.

I would not do re-calibration unless you know all of the potentiometers are in range. Forward, reverse, throttle, etc. If any of them are out of range it will not work and tractor will not move. The only time you need to do a re-calibrate is if you have replaced something in the hydraulic part, like a pump. The re-calibrate is to let the computer know how much the tires move vs potentiometer position.
Hi
I returned the 4310 E-HYDRO don't move and it shows these codes:
--**(long-long-short-short)
*-** (short-long-short-short)
***- (short-short-short-long)
*---(short-long-long-long)
I verified wires are ok fuses also ok !!!
any suggestion!!!

Hi all
I adjusted the three potentiometer (forward, reverse and throttle) and the flash codes go off
but this code is still flashing ( *---) the fault is about propotional valve.
for information I tried calibration when I arrived at step to calibrate valve I have an other flash code (**-*) flywheel sensor when I quit the calibration mode I have only propotional valve fault
Any thoughts or help would be a great it is urgent

The code means you need to check the coil on the forward proportional valve with a ohm meter. If the coil checks good it is in the wires between the valve and controller.

For some reason the controller is not getting a valid response from the forward or reverse proportional valve. Did you check both? Have you followed every direction on the calibration sequence?
I remember when I calibrated mine I tried for days. When I finally did get it it was because I did the first step. Start with range selector in neutral and park brake set. I had been skipping it.
Next I would start rechecking everything again. The answer is there we just need to see it.
