BCU 000096.03 – Fuel Level Sensor High Voltage Fault. John Deere System Advisory.

BCU 000096.03 (BCU 96.03)

Code: 000096.03

Shortcode: 96.03

Description:

Error code BCU 000096.03 relates to an issue with the B176 fuel level sensor in John Deere equipment. This fault occurs when the Basic Control Unit (BCU) detects unusually high voltage from the sensor, which could be indicative of an open circuit or a short to a 12-volt source. High voltage readings like this can lead to inaccurate fuel level readings, affecting the operation and fuel management of the vehicle.

Reaction:

The BCU may respond to this fault by altering fuel gauge readings or activating a warning indicator to alert the operator of potential inaccuracies in fuel measurement, which could affect operational planning and vehicle usage.

Recommendations:

  • Inspect Fuel Level Sensor and Wiring: Check the B176 fuel level sensor for any signs of damage or corrosion. Examine the wiring harness for shorts to power sources or signs of wear and exposed wires.
  • Measure Sensor Voltage: Use a multimeter to measure the voltage at the fuel level sensor. Compare these readings with manufacturer specifications to determine if they are within a normal range.
  • Repair or Replace Faulty Components: Repair any damaged wiring or connectors. If the sensor itself is faulty, replace it to ensure accurate fuel level readings.
  • Test After Repairs: Once repairs are made, test the system to ensure the fuel gauge reads accurately and no high voltage errors are detected.
  • Clear Fault Codes: Reset the BCU to clear the diagnostic trouble codes and verify that no further codes are generated during operation.

Note:

Maintaining accurate fuel level readings is crucial for proper vehicle operation. Regular checks and maintenance of the fuel sensing system can help avoid issues that lead to inaccurate readings or potential vehicle downtime. Addressing faults promptly ensures that all related vehicle systems continue to operate efficiently and reliably.
