1. 1

   Assess the status to determine if the error is active or stored; if the error exists only temporarily, it can be ignored

2. 2

   Inspect battery health and battery terminals

3. 3

   Inspect the main power and ground harness connections to the EDC for corrosion, loose pins, or chafed wires that could cause a sudden voltage drop

4. 4

   Use a diagnostic tool to clear the DTC and operate the machine under normal load to see if the code returns

1. 1

   Clear the Code

   If the machine operates normally and the code does not return after clearing, no further action is required.

2. 2

   Address Wiring Issues

   If you found voltage drops or loose grounds during the diagnostic phase, repair the affected harness sections and re-test.

3. 3

   Replace the EDC

   If the wiring is intact, power delivery is stable, and the code remains active (or causes persistent engine performance/injection dropouts), the EDC has suffered an internal hardware failure and must be replaced.

4. 4

   Reprogram the Module

   If the EDC is replaced, you must connect the CNH Electronic Service Tool (EST) and follow the appropriate service tool procedure to flash the controller and 'Restore Self Learning Parameters'.
