Description:

This error code, EPC 524173.03, is generated when the control unit measures a voltage of more than 4.7 volts at the signal input from channel 1 of the clutch pedal potentiometer (B65, lead 6114). This indicates a problem at the signal lead or at the potentiometer ground connection.

Reaction:

When this error is detected, the system may not accurately interpret the clutch pedal position, leading to potential issues with clutch operation and overall vehicle performance.

Recommendations:

Inspect Wiring and Connections:

• Check the wiring and connections to the clutch pedal potentiometer for any signs of damage, loose connections, or corrosion. Pay special attention to the signal lead and ground connections. Repair or replace as necessary.

Test Clutch Pedal Potentiometer:

• Use diagnostic tools to test the clutch pedal potentiometer (B65) for proper functionality. Replace the potentiometer if it is found to be defective.

Verify Signal Voltage:

• Measure the voltage at channel 1 (lead 6114) to ensure it is within the correct range (below 4.7 volts). Investigate and resolve any sources of excessive voltage.

Check Ground Connection:

• Ensure that the ground connection for the potentiometer is secure and free of corrosion.

Reset and Test System:

• After addressing the issues, reset the system and test the clutch pedal potentiometer to ensure it operates correctly and that the error code does not reoccur.

Note:

Regular inspection and maintenance of the clutch pedal potentiometer and its associated wiring are crucial for ensuring reliable operation and preventing voltage issues.
