Clean connectors and reconnect tightly.

GreenStar™ harness is improperly connected.

Power down machine and system, disconnect harness, clean, and install properly.

There is an electrical short in harness.

Check electrical wiring for breaks, shorts, and damage.

The Application Controller 1100 was connected with the machine powered on and (or) codes active on the machine.

Turn OFF the machine and completely disconnect the Application Controller 1100 from system. (Reference Disconnecting the Active Implement Guidance System.) Start the machine and allow the display to completely boot up. Turn OFF the machine and reconnect the Application Controller 1100 and all harnesses.

The Application Controller 1100 is not communicating with CAN bus after key cycle.

Verify that the Application Controller 1100 has switched power. If the Application Controller 1100 has constant power, it does not power down and will not appear on display when machine is powered back on.

Verify that 9-pin SCV option connector is plugged into machine.

Clean connectors and reconnect tightly.

SCV is not in detent.

Ensure that SCV is in detent and not in float mode. If the SCV lever remains in forward position, then it is in float mode.

Incorrect Setup.

Verify that correct control type is selected, SCVs are selected in the Active Implement Guidance setup, and power has been cycled.

SCV selection is not correct in CommandCenter™ (R series).

On the CommandCenter™, select the SCV being utilized.

Remove the check valves.

Hydraulic hoses are reversed.

Switch positions of hydraulic hoses and calibrate maximum left, center, and maximum right positions.

Application Controller 1100 was connected while machine was running, creating hydraulic control unit fault codes.

(Reference Reset Application Controller 1100 for more information.)

Drive toward the next guidance line and select AutoTrac™ resume. Implement acquires line and begins tracking.

Change Implement Shifter mode to Shifter Stay On Disabled.

Hitch travel is not parallel to the machine rear axle.

Install an implement feedback sensor and sensor harness. Change the control selection from Implement Shifting to Implement Steering. Calibrate left, center, and right positions.

Switch hoses in SCV outlets.

Implement steering calibration was done with right and left limits reversed.

Reverse right and left inputs and perform implement steer calibration again.

Incorrect implement feedback sensor connector plugged in to the wheel angle sensor.

Plug in the correct implement feedback connector for SCV selected in the settings.

To bring up AC mode, push the correct SCV control lever into detent.

Check for leakage.

(Reference service section for more information.)

Repair or replace the cylinder. Contact your John Deere dealer or any other qualified service provider for assistance.

There is insufficient machine hydraulic pressure.

Check machine hydraulic pressure.

(Reference machine Operator's Manual for more information.)

Ensure that hydraulic oil is at operating temperature.

Use correct size hydraulic cylinders for machine pressure.

Counterbalance valve improperly adjusted.

Adjust counterbalance valve cartridges and perform threshold calibration.

Hydraulic hoses are connected improperly or poorly.

Check hose O-rings, connect properly, and tighten connections.

Valve is frozen.

Manually cycle hydraulic cylinders to the full right and left. If condition repeats, oil may be contaminated, causing plugging, or SCV may require a shuttle valve to prevent it from going into Desilting Mode during low flow conditions.

Active Implement Guidance settings are incorrect.

Verify system moves fluidly with extend and retract tests, and adjust sensitivities and thresholds accordingly.

Refer to the System Status table in Troubleshooting.

Application Controller 1100 was connected while machine was running, creating hydraulic control unit fault codes.

1. Turn OFF machine.

2. Disconnect the Application Controller 1100, constant power harness, and option connector from the external rear panel of cab.

3. Disconnect CAN bus T-connectors and connect 4-pin connector directly to the ISO implement connector.

4. Start machine. Once all systems start up, turn OFF machine.

5. Reconnect the Application Controller 1100, constant power harness, and option connector.

6. Reconnect CAN bus T-connectors between 4-pin connector and ISO implement connector.
