96 AutoFarm GPS AutoSteer

Steering is slow or sluggish in AutoSteer mode

• Wrong load sense connections. Pump is not being stroked up.

• Bad power beyond hookup

• Missing plug or orifice in position 13C

• Bad LS shuttle valve. Check o-rings. Replace shuttle valve if necessary.

• Missing plug or orifice in position 13A.

Wheels only turn in one direction in AutoSteer mode

• Bad SAM harness

• Bad valve harness (4-pin connector harness)

• Bad coil on one side of proportional valve

• Leaking LS shuttle valve in AutoSteer valve.

• Jammed spool on proportional valve. Could be caused by severe oil contamination.

• Bad pilot check valve cartridge. Leaking o-ring on one pilot check valve cartridge.

Pump remains stroked up too long or when not

AutoSteering Pump pressure is always high

• Missing LS bleed-down orifice in position 13A (only for Power Beyond installations)

• LS bleed orifice in position 13A is dirty and blocked. (from oil contamination or following service). (only for Power

Beyond installations)

• Wrong LS hose connections or wrong type of installation for the type of machine.

Valve is noisy or chatter occurs

• Load Sense hoses are too long. Use shorter hoses. Install valve closer to hookup point to shorten hoses.

• Loose hoses. Secure hoses or use shorter hoses.

• Vehicle pump is generating pressure oscillations that generate noise. Install hydraulic accumulator.

• Review complete hydraulic installation

The wheels vibrate or steering is too “twitchy” in

AutoSteer mode

• Wrong vehicle selected or wrong vehicle type selected. Confirm if correct vehicle profile was selected.

• Wrong calibration. Repeat actuator calibration. Repeat wheel angle sensor calibration

• Wrong tuning gains or tuning not done. Steering gain too high. Repeat a complete tuning routine.

• Response rate slider set too high. Lower the response rate in main AutoSteer screen.

• Wrong CPF parameters for 12V valve.

• Bad wheel angle sensor or wheel angle sensor bad cable.

• Valve flow is too high for the size of the machine. This can happen on very small tractors.
