1. 1

   Connect the New Holland Electronic Service Tool (EST)

2. 2

   Reload the Engine Dataset by flashing or updating the engine controller with the latest software to rule out data corruption regarding injection angles and energizing times

3. 3

   Clear the codes and run the machine to see if the fault persists

1. 1

   Disconnect battery

   Disconnect the battery to prevent electrical arcing.

2. 2

   Locate EDC

   Locate the EDC (Engine Controller Unit) on the engine block.

3. 3

   Disconnect connectors

   Disconnect the EDC7 connectors (lever-style connectors) from the ECU.

4. 4

   Remove controller
