Case IH 3752 – Engine Controller: Zero Fuel Calibration (ZFC) issue

Error in the plausibility of the energizing times of the zero fuel quantity calibration

• Farmall
• skid steer
• Skid Steer Loaders (SSL)
• Compact Track Loaders (CTL)
• tractors with F5C engines

1. 1

   Connect the appropriate Case IH Electronic Service Tool (EST) to the machine's diagnostic port

2. 2

   Verify the presence of code 3752 (Zero Fuel Calibration error)

3. 3

   Attempt to Reload the Engine Dataset (reflash/update the engine calibration software) to see if the plausibility error clears

1. 1

   Reload Engine Dataset

   Use the service tool to reload the engine dataset.

2. 2

   Evaluate

   Cycle the key and re-check for the fault code.

3. 3

   Replace Engine Controller

   If the fault persists after the dataset has been successfully reloaded, the Engine Controller (EDC) has suffered an internal failure and must be replaced.

4. 4

   Restore Parameters

   If the EDC is replaced, you MUST follow the appropriate service tool procedure to restore the engine's Self-Learning Parameters.
