Case IH 11060 – Armrest Controller: Aux 1st remote valve FLOW potentiometer is failed in the Armrest Controller

The potentiometer responsible for setting the hydraulic flow rate for the #1 auxiliary remote valve is sending an erratic, out-of-range, or dead signal to the computer. This disables the remote or forces it into a default/safe state.

1. 1

   Live Data Monitoring: Use the tractor's diagnostic display (A-post monitor or Pro 700/1200 display) to monitor the live voltage or percentage of the 1st remote flow potentiometer. Slowly turn the dial and watch for dead spots, erratic jumping, or a signal stuck at 0V or 5V.

2. 2

   Calibration Check: Attempt to recalibrate the armrest hydraulic controls. If the potentiometer is failing, the calibration will usually fail or throw a light.

3. 3

   Wiring & Connector Inspection: Open the armrest console and inspect the wiring harness connecting the flow dial to the armrest controller board. Look for pinched wires, loose connector pins, or corrosion.

4. 4

   Multimeter Test: Disconnect the potentiometer and test its resistance sweep with a multimeter. If the resistance drops out or spikes infinitely while turning the dial, the component is internally damaged.

1. 1

   Power Down

   Turn off the tractor, remove the key, and disconnect the battery to prevent shorting sensitive CAN-bus electronics.

2. 2

   Disassemble the Armrest

   Remove the retaining screws from the underside or sides of the armrest console to lift off the top cover.

3. 3

   Locate the Component

   Locate the 1st remote flow control dial. Note that on many Case IH models, the flow and timer potentiometers are integrated into a single sealed Remote Valve Control Pod or the main Armrest Control Unit board.

4. 4

   Disconnect and Remove

   Unplug the electrical connector for the 1st remote dial/pod. Remove the mounting screws or plastic retaining clips holding the potentiometer assembly in the armrest housing.

5. 5

   Install the New Part

   Seat the new potentiometer or control pod into the housing and secure it with the retaining screws. Reconnect the wiring harness.

6. 6

   Reassemble

   Carefully reinstall the armrest cover, ensuring no wires are pinched.

7. 7

   Recalibrate

   Reconnect the battery. Turn the key on and enter the tractor's diagnostic/calibration menu to perform an EHR (Electro-Hydraulic Remote) calibration. The controller must learn the minimum and maximum voltage values of the new potentiometer to function correctly.
