Hydraulic Bleed/Check Troubleshooting

Before running SureForce for the season you’ll want to verify functionality by running a hydraulic bleed and hydraulic check. If the hydraulic check/bleed are not functioning you’ll need to verify the following:

1. To run the Hydraulic Check or Bleed you will need to be on the Main Down Force Setup screen, and not have a current event on the run screen. If you do not have the option for Hydraulic Check or Bleed you’ll need to create a configuration using SureForce and not Row Modules for downforce.

2. Verify your max downforce setting is set correctly.

3. Verify hydraulics are connected properly and turned on. Make sure the pressure connections on the main valve (P1, P2, P3) are going to the bottom side of the row valves. There should be a P stamped on them where pressure is. The return lines (R1, R2, R3) should be going to the top of the row valves stamped with an R.

4. The implement will need to be lifted. To verify the lifted state there should be no blue light on any implement switch modules.

Pressure

You will need to be seeing a minimum pressure of 500 PSI (recommended pressure of 2500-3000 PSI). This can be verified in the PCM diagnostics window.

* If you have pressure to the main valve block, but do not see pressure in the diagnostics window you’ll need to verify cabling and calibration. To calibrate the pressure sensor ensure that you have 0 pressure in the hydraulic line and select calibrate pressure sensor.

* If your cabling or pressure sensor is deemed to be faulty, you can still run SureForce by disabling the pressure sensor and entering a manual pressure. If going this route it is recommended to put a pressure gauge on the system and verify tractor pressure. Then use the value from the gauge as your manual pressure.

Battery Voltage

You will need to see a ≈12v on battery voltage which can be verified in the PCM diagnostics window. Here is how to test for voltage out of your generator. If you do not have a Generator or Distribution box you’ll need to verify power from cable 4005702 on pins 2 to 11.

Main Valve Functionality

If you have verified the above settings you can then verify voltage to the Main Valve block. Any time we are engaging hydraulics (Hydraulic Check, Hydraulic Bleed, or running in the field) we will send voltage to the main valve block (≈12v). If we are not seeing voltage you'll need to re-verify cabling and the above steps. If you are seeing voltage, but not getting pressure on the planter side of the block there may be an issue with the valve block or hydraulics.
