Case IH U60 – Transmission Controller / EDC (Electronic Draft Control) module: Out Of Range Calibration Value

Triggered during the transmission or Electronic Draft Control (EDC) calibration process when the controller detects a sensor value (such as from a clutch potentiometer or torque sensor) that falls outside the acceptable programmed parameters.

1. 1

   Park the tractor on level ground, place all shift levers in neutral, apply the parking brake, and block the front and rear wheels.

2. 2

   Ensure the transmission oil temperature is within the correct range (between 20°C and 50°C for 24x12 transmissions).

3. 3

   Turn off the air conditioning (if fitted) and deselect all electrical and hydraulic services.

4. 4

   If calibrating the EDC: Place a weight of approximately 200 kg on the lift arms to overcome linkage resistance, turn all EDC controls fully clockwise, and position the raise/work switch to the WORK position.

1. 1

   Enter Calibration Mode

   With the key switch OFF, depress and hold the upshift switch.

2. 2

   Start engine in calibration mode

   Turn the key switch ON. Within three seconds, depress the downshift switch, start the engine, and then release the switches. (Alternative method: Install OEM diagnostic tool 380000488 into the diagnostic port).

3. 3

   Set engine speed

   Set the engine speed to 1200 RPM.

4. 4

   Verify calibration readiness

   The transmission display will show 'CAL', indicating the transmission is ready for calibration.

5. 5

   Calibrate clutch packs

   Use the High and Low range buttons as prompted by the display to calibrate the clutch packs. The display will show a number that increases during the calibration of each clutch.

6. 6

   Monitor calibration progress

   The display will show 'SOC' during the process and will display 'END' to signify successful completion.

7. 7

   Inspect sensors and wiring

   If the U60 code persists and calibration repeatedly fails, physically inspect the clutch potentiometers, flywheel speed/torque sensor, and their wiring harnesses.
