John Deere 524173.02 – PTR / CAB / EPC / PTP / TID: Clutch Pedal Compare Error / Clutch Pedal Sensor Voltage Conflict

The control unit has detected a mismatch between the output signals of the clutch pedal potentiometer (sensor B65). The system requires that the voltage at Channel 1 (lead 6114) must be exactly double the voltage of Channel 2 (lead 6007). When this ratio is incorrect, the code is triggered, and the control unit may disable clutch functionality to prevent unsafe operation.

1. 1

   Inspect the clutch pedal potentiometer (B65) for physical damage, misalignment, or obvious malfunction.

2. 2

   Verify Voltage Ratios: Use a multimeter or diagnostic tool to measure the voltages at Channel 1 (lead 6114) and Channel 2 (lead 6007) of the clutch pedal potentiometer. Confirm whether the voltage at Channel 1 is double the voltage at Channel 2.

3. 3

   Inspect Wiring and Connections: Check all wiring and connectors related to the clutch pedal position sensor. Look for loose connections, corrosion, short circuits, or open circuits that could be skewing the voltage readings.

4. 4

   Check Software: Ensure that the control unit (PTR/CAB/EPC) software is up-to-date, applying any available manufacturer patches.

1. 1

   Repair Wiring

   If the diagnostic checks reveal damaged wiring, corroded pins, or a short circuit in the harness leading to the B65 sensor, repair or replace the affected wiring.

2. 2

   Replace the Sensor

   If the wiring is intact and the voltage ratio remains inconsistent, the clutch pedal potentiometer (B65) has failed internally and must be replaced.

3. 3

   Reset and Test

   After addressing the wiring or replacing the sensor, clear the diagnostic trouble codes from the system.

4. 4

   Monitor Operation

   Test the clutch pedal operation during use to ensure the sensor provides accurate, consistent readings and that the 524173.02 code does not return.
