BCU 000096.04 – Fuel Level Sensor Low Voltage Fault. John Deere System Advisory.

BCU 000096.04 (BCU 96.04)

Code: 000096.04

Shortcode: 96.04

Description:

Error code BCU 000096.04 is triggered when the B176 fuel level sensor in John Deere equipment exhibits abnormally low voltage levels, indicative of a short to ground. This condition may lead to incorrect fuel level readings, which can adversely affect the operation and fuel management of the machinery.

Reaction:

In response to this fault, the Basic Control Unit (BCU) may adjust the fuel gauge to display incorrect levels or activate warning indicators to notify the operator of potential discrepancies in the fuel measurement, potentially impacting operational efficiency and planning.

Recommendations:

  • Inspect Fuel Level Sensor and Wiring: Thoroughly examine the B176 fuel level sensor and its wiring. Look for any signs of damage, wear, or corrosion that could contribute to a short to ground. Pay particular attention to the insulation and connections.
  • Measure Sensor Voltage: Utilize a multimeter to measure the voltage output from the fuel level sensor to confirm if it is below the normal expected range.
  • Repair or Replace Damaged Components: Repair any damaged wiring or connectors. If the sensor itself is determined to be faulty, replace it to ensure the accuracy of fuel level readings.
  • Test System Functionality: After making the necessary repairs, test the fuel level measurement system under various conditions to ensure it operates correctly.
  • Clear Diagnostic Codes: Reset the BCU to clear any stored fault codes and perform a system check to confirm that the issue has been resolved and no new codes appear.

Note:

Regular maintenance of the fuel sensing system is essential for accurate fuel management and efficient operation of John Deere machinery. Prompt attention to issues such as voltage irregularities can prevent operational disruptions and ensure that all related vehicle systems function effectively. Addressing these issues quickly helps maintain the reliability and longevity of the equipment.
