DESCRIPTION:This diagnostic is typically an under pressurized diesel exhaust fluid (DEF) system. MONITORED PARAMETER:DEF pump speed vs. DEF pressure. TYPICAL ENABLING CONDITIONS:DEF pump enalbed or on-off-cycle request. EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:Continuous until resolved. DASH LAMPS:None ENGINE REACTION:None VERIFICATION:Parked regeneration/Selective catalyst reduction SCR ADS self-check routine. NOTE: If any other codes are active, fix those first. PROBABLE CAUSES:1. Inspect the DEF dosing unit and DEF pump harness wiring & connectors.2. Check all DEF lines for damage/blocks/kinks.3. DEF pump suction filter.4. DEF dosing unit inlet filter.5. DEF tank header.6. DEF tank supply filter.7. Replace the pressure relief valve....

DESCRIPTION:Over pressurized Diesel Exhaust Fluid (DEF) system. MONITORED PARAMETER:DEF pump speed vs. DEF Pressure. TYPICAL ENABLING CONDITIONS:DEF pump enabled OR on-off-cycle request. EXECUTION FREQUENCY:Continuous when enabling conditions are met. TYPICAL DURATION:2 mintues DASH LAMPS:None ENGINE REACTION:None VERIFICATION:SCR ADS self check. NOTE: If any other codes are active, fix those first. PROBABLE CAUSES:1. Inspect the DEF dosing unit and DEF pump harness wiring & connectors.2. Check all DEF lines for damage/blocks/kinks.3. DEF pump suction filter.4. DEF dosing unit inlet filter.5. DEF tank header.6. DEF tank supply filter.7. Replace the pressure relief valve. Detroit DD16 GHG14 (2014-16) Fault Code: SPN 520326 FMI...

DESCRIPTION:This fault code sets when the actual Diesel Exhaust Fluid (DEF) pump speed is low compared to the calibrated DEF pump speed that is needed to achieve the pressure. MONITORED PARAMETER:DEF Pump Speed and DEF Pressure. TYPICAL ENABLING CONDITIONS:DEF dosing enabled. EXECUTION FREQUENCY:Continuous when enabling conditions are met. TYPICAL DURATION:Continuous until resolved. DASH LAMPS:CEL ENGINE REACTION:None VERIFICATION:SCR ADS self check. NOTE: If any other codes are active, fix those first. PROBABLE CAUSES:1. Inspect the DEF dosing unit and DEF pump harness wiring & connectors.2. Check all DEF lines for damage/blocks/kinks.3. DEF pump suction filter.4. DEF dosing unit inlet filter.5. DEF...
