John Deere 3695.14 – Engine Control Unit (ECU) or Engine Interface Control Unit (EIC): The Calculated Soot Loading In The DPF Is High, However The Regen Switch Is Turned Off. Ensure The Switch Is In Auto Position.
Issue description
This diagnostic trouble code indicates that the calculated amount of soot inside the Diesel Particulate Filter (DPF) has reached a high level requiring an active regeneration to burn it off. However, the system is unable to initiate the exhaust filter cleaning process because the Auto Regeneration feature has been manually disabled by the operator (the inhibit switch is active), or the engine coolant temperature is too low to permit regeneration. If ignored, continued operation will result in engine derating and loss of machine availability.

Check the cause
Verify that the DPF Regeneration switch or monitor setting is not set to 'Disable' or 'Inhibit'
Verify the engine coolant temperature is reaching normal operating levels (regeneration is inhibited if the engine is too cold)
Look for other active codes (such as EGR temperature sensor codes or coolant temp codes) that might be forcing the ECU to inhibit regeneration
View the DPF soot level on the monitor to determine if a standard Auto Regen will suffice or if a Parked Regen is required
Repair steps
Enable Auto Regeneration
Navigate to the Engine settings page on the monitor (or use the physical dash switch) and change the exhaust filter cleaning setting from 'Disabled' to 'Auto' (Enabled).
Resume Normal Operation
Operate the machine under a normal or heavy load to allow the exhaust temperatures to rise and the Auto Regeneration to complete.
Perform a Parked Regeneration
If the soot level has gotten too high for an Auto Regen, the monitor will display a 'Parked Cleaning Required' icon (often accompanied by a red stop lamp). Park the machine in a safe, well-ventilated area away from combustible materials. Apply the parking brake, leave the engine running, and initiate a Parked Regeneration via the monitor or switch. Do not interrupt the process until it completes automatically.
Service ADVISOR Forced Regen
If the soot level has exceeded the threshold where a parked regeneration is permitted, the ECU will lock out operator-initiated regenerations. A qualified John Deere technician must connect a laptop with Service ADVISOR to perform a forced service regeneration.
DPF Cleaning/Replacement
If the DPF is completely face-plugged with soot/ash and cannot be regenerated via Service ADVISOR, the DPF must be removed and professionally cleaned or replaced.
