Case IH 11132 – Auxiliary Valve Controller (AUX67 or AUX89): 1st remote TIMER potentiometer SENSE is failed high.

The controller is receiving a voltage signal from the timer adjustment dial (potentiometer) for the 1st hydraulic remote that exceeds the maximum expected threshold. A "failed high" condition typically points to a short to power in the wiring, an open ground circuit, or a complete internal failure of the potentiometer itself.

• STX Steiger
• Steiger Series (335, 380, 435, 500, 535, Quadtrac)
• Magnum Series
• Puma & Maxxum Series

1. 1

   Inspect the armrest control panel for physical damage to the 1st remote timer knob or liquid spills that may have shorted the board.

2. 2

   Access the wiring harness beneath the armrest console and check the connector leading to the 1st remote timer potentiometer for loose pins, corrosion, or damaged wires.

3. 3

   Test the circuit with a multimeter to rule out a short to a 5V/12V power source or a broken ground wire.

4. 4

   Attempt to recalibrate the hydraulic remotes using the tractor's A-post display or Pro monitor (hold the PROG key while turning the ignition ON, navigate to the ARM section, and enter calibration mode). If values jump erratically, the potentiometer has a dead spot.

1. 1

   Disconnect Power

   Turn off the tractor and disconnect the battery to prevent electrical damage to the armrest modules.

2. 2

   Disassemble the Armrest

   Remove the retaining screws on the armrest console to access the underside of the remote valve control panel.

3. 3

   Remove the Faulty Component

   Locate the specific potentiometer for the 1st remote timer. Pull off the external timer control knob. Disconnect the electrical pigtail/connector from the potentiometer. Note: On some newer Steiger/Magnum models, the potentiometers are soldered directly to the armrest circuit board. If you cannot desolder the individual potentiometer, the entire remote control circuit board must be replaced.

4. 4

   Install the New Part

   Mount the new potentiometer, secure it with its retaining nut, and press the timer control knob back onto the shaft.

5. 5

   Reassembly

   Reconnect the electrical harness, reassemble the armrest housing, and reconnect the battery.

6. 6

   Recalibrate

   Turn the key on and perform the EHR (Electronic Hydraulic Remote) calibration procedure via the A-post or armrest display so the controller can learn the new potentiometer's base voltage values.
