John Deere FCC Error Codes / FCC Fault Codes
Overview of John Deere FCC Diagnostic Trouble Codes
The John Deere FCC control software is integral to various vehicle functions, including controlling wipers, processing signals from turn-signal levers, and managing reverse drive levers. The FCC control software is part of the instrument unit and interfaces with multiple vehicle systems.
Key Functions and Signal Processing
The FCC control software receives and processes signals from:
- Reverse Drive Lever (PowrQuad™ Transmission)
- Reverse Drive Lever (AutoPowr™/IVT™ Transmission)
- Reverse Drive Lever (DirectDrive Transmission)
- Instrument Unit (PowrQuad™ Transmission)
- Instrument Unit (AutoPowr™/IVT™ Transmission)
- Instrument Unit (DirectDrive Transmission)
- Turn-Signal Lever
- Windshield and Rear Window Wiper Switches
- Light Switch
- Windshield Wiper Shut-Off Switch
These signals are processed and made available on the vehicle CAN bus (500 kBd). Additionally, the reverse drive lever signals are forwarded directly to the corresponding transmission control software (TIA, TID, or TIQ).
Fuel Conditioning Control (FCC)
FCC codes specifically address the Fuel Conditioning Control system. This system ensures the engine receives clean and properly conditioned fuel, which is crucial for maintaining engine health and performance. FCC error codes related to this system can indicate issues such as poor engine performance, increased wear, or potential breakdowns.
Common John Deere FCC Fault Codes
- FCC 000158.00 – Instrument Unit, Supply Voltage (ELX) Too High
- Description: Supply voltage above 15.5 volts with engine speed above 500 RPM.
- Reaction: Limited or no function of the control software.
- Solution: Inspect alternator, voltage regulator, and wiring connections.
- FCC 000158.01 – Instrument Unit, Supply Voltage (ELX) Too Low
- Description: Supply voltage below 12.5 volts with engine speed above 1500 RPM.
- Reaction: Limited or no function of the control software.
- Solution: Check battery, alternator, and electrical connections.
- FCC 000628.02 – Control Software, Internal Error
- Description: Error reading the internal module (EEPROM).
- Reaction: Limited or no function of the control software.
- Solution: Restart software, check EEPROM connections, update software.
- FCC 000639.14 – Vehicle CAN Bus (500 kBd), Very High Error Rate
- Description: High error rate in CAN Bus messages.
- Reaction: Limited or no function of the control software.
- Solution: Diagnose CAN bus, inspect wiring, update software.
- FCC 002825.31 – Reverse Drive Lever, Fault
- Description: Incorrect values detected when reverse drive lever is in neutral or reverse.
- Reaction: Limited or no function of the reverse drive lever.
- Solution: Inspect sensor connections, recalibrate lever, test sensors.
Importance of Addressing FCC Error Codes
Addressing FCC error codes promptly is essential to prevent further damage and ensure optimal performance of your John Deere equipment. Regular maintenance, accurate diagnostics, and timely repairs are key to minimizing downtime and maximizing productivity.
