1. 1

   Connect your CNH Electronic Service Tool (EST) or compatible diagnostic scanner

2. 2

   Pull all active and stored fault codes from the Engine ECU

3. 3

   Look for the primary fault codes that are causing the reduction in power (e.g., DPF restriction, engine overheating, low engine oil pressure, EGR system faults, or critical sensor failures)

1. 1

   Identify the Root Cause

   Review the list of active fault codes and identify the primary code(s) responsible for triggering the engine protection mode.

2. 2

   Troubleshoot the Primary Fault

   Follow the OEM diagnostic steps for the specific primary fault code(s) you found.

3. 3

   Perform Repairs

   Replace the faulty sensor, clear the DPF restriction, or repair the wiring issue as dictated by the primary fault.

4. 4

   Clear Codes

   Once the root cause is repaired, use the diagnostic tool to clear all fault codes.

5. 5

   Verify Operation

   Start the machine and run it under load. Verify that full engine power is restored and that code ENG 3655 does not return.
