John Deere 000598.02 – PTP/EPC: Clutch Pedal Switch/Sensor Circuit Conflict

The transmission control unit has detected a discrepancy between the signals from the clutch pedal switch and the clutch pedal position sensor (potentiometer). This conflict occurs when the control module receives contradictory information about the clutch pedal's position, such as the switch indicating the pedal is released while the sensor suggests it is depressed.

1. 1

   Visually inspect the clutch pedal assembly, its sensors, and the associated wiring harness for any visible damage, loose connections, or corrosion

2. 2

   Ensure that the clutch pedal is fully released and that the operator's foot is not resting on it, as this can sometimes cause intermittent faults

3. 3

   Perform a 'PTR—Clutch Pedal Switch Circuit Test' to check for correct voltage signals and continuity of the clutch pedal switch and potentiometer

4. 4

   Check for specific sub-codes (e.g., PTR 000598.02 for Clutch Switch Open With Pedal Up, or PTR 000598.04 for Clutch Switch Signal Failed Low) to help pinpoint whether the issue is with the switch itself or the signal

1. 1

   Access the components

   Locate the clutch pedal sensor and switch, which are situated on the clutch pedal assembly.

2. 2

   Perform diagnostic tests

   Execute the 'PTR—Clutch Pedal Switch Circuit Test' using a multimeter to verify the integrity of the sensor, switch, and wiring harness.

3. 3

   Isolate the fault

   Based on the test results, determine if the fault lies with the clutch pedal sensor, the switch, or the wiring harness.

4. 4

   Replace faulty components

   If the sensor or switch is determined to be faulty, it should be replaced. If the wiring harness is damaged, it will need to be repaired or replaced.

5. 5

   Clear fault codes

   After the repair, use a diagnostic tool to clear the fault code from the control unit's memory.

6. 6

   Verify repair

   Operate the tractor, using the clutch pedal multiple times to ensure the fault code does not reappear.
