John Deere 1515 – HCU (E01) or LC1 Control Unit: HEADERTRAK System Not Calibrated for Attached Header

The HEADERTRAK system (also known as Active Header Height Control or CONTOUR MASTER) has not been calibrated for the currently attached header. This fault is triggered when a new or different header is attached to the combine, or when components of the height sensing system are replaced. The system must learn the header's sensor value range to accurately control its position relative to the ground. Failure to calibrate will result in improper operation or performance of the automatic header height and tilt features.

1. 1

   Ensure the combine and header are parked on a firm, level surface (preferably concrete).

2. 2

   Verify the header is securely attached to the combine.

3. 3

   Inspect the header's electrical harness connection to the combine; a loose or disconnected harness can prevent recognition and may trigger an 'ER02' code.

4. 4

   Check header height sensors, arms, and linkages for damage, binding, or excessive material buildup.

5. 5

   Determine if the feeder house requires calibration first (an 'ER01' error code indicates feeder house calibration must be completed before header calibration).

1. 1

   Prepare machine for calibration

   Start the combine and bring it to operating temperature on a level surface.

2. 2

   Access calibration mode (Triple Display Tachometer models)

   Press the diagnostic switch on the armrest controls ('dIA' will appear). Press the calibration switch ('CAL' will appear). Use the up or down arrow keys until 'CAL' and 'hdr' are displayed, then press the enter switch to access the header calibration mode.

3. 3

   Set minimum sensor setting (Triple Display Tachometer models)

   Lower the header completely until it rests flat on the ground. For HYDRAFLEX heads, decrease the pressure until it is below 1000 psi. Press the calibration switch to save the 'down' position.

4. 4

   Set maximum sensor setting (Triple Display Tachometer models)

   When prompted for the 'up' position ('H-UP'), raise the header completely with the header raise/lower switch. Press the calibration switch again ('EOC' will appear), then press the enter switch to save the calibration values and exit.

5. 5

   Access calibrations menu (Modern displays, e.g., S700)

   With the header connected, access the calibrations menu by pressing the Menu button on the display. Select 'Calibrations & Procedures' and then tap 'Header Calibration'.

6. 6

   Perform calibration (Modern displays, e.g., S700)

   Press the 'Calibrate' button and follow the on-screen instructions (typically involving setting the machine to high idle, leveling the header, lowering it to the ground, and then raising it fully). Once successful, press 'Save' to store the calibration values and exit.
