Detroit DD16 GHG14 (2014-16) Fault Code: SPN 520328 FMI 7 (ACM) Diesel Exhaust Fluid System has Been Over-Pressurized
Posted by Diezel Solutions on
DESCRIPTION:Diesel Exhaust Fluid (DEF) pressure relief valve stuck closed. MONITORED PARAMETER:DEF Pressure TYPICAL ENABLING CONDITIONS:When service routine is enabled and during in-use checks under non-dEF dosing conditions. MONITOR SEQUENCE:None EXECUTION FREQUENCY:Service tool and during in-use checks under non-DEF dosing conditions. TYPICAL DURATION:2 Seconds 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...
Detroit DD16 GHG14 (2014-16) Fault Code: SPN 520329 FMI 31 (ACM) Non Diesel Exhaust Fluid Flow Situation
Posted by Diezel Solutions on
DESCRIPTION:Diesel Exhaust Fluid (DEF) pump speed low. MONITORED PARAMETER:DEF pump speed. TYPICAL ENABLING CONDITIONS:DEF pump enabled and cannot operate above a DEF pump speed threshold. MONITOR SEQUENCE:DEF pump is enabled. EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:Two seconds DASH LAMPS:CEL ENGINE REACTION:None VERIFICATION:Parked regeneration NOTE: Follow troubleshooting found in 5435-7.

Detroit DD16 GHG14 (2014-16) Fault Code: SPN 520332 FMI 17 (ACM) Diesel Oxidation Catalyst Inlet Temperature Out of Range Low Preventing HC Dosing
Posted by Diezel Solutions on
NOTE: The fault indicates that the High Idle Regen (HIR) was aborted due to the Diesel Oxidation Catalyst (DOC) inlet temperature not reaching the minimum of 270°C (518°F) to initiate dosing during an HIR . DESCRIPTION:DOC inlet temperature out of range low. MONITORED PARAMETER:Exhaust temperature. TYPICAL ENABLING CONDITIONS:Always on MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:Two seconds DASH LAMPS:MIL ENGINE REACTION:None VERIFICATION:Parked regen NOTE: If any other codes are present, fix those first. PROBABLE CAUSES:1. Intake throttle valve.2. Exhaust leaks.3. Intake manifold leaks.4. Intake air system leaks (Including charge air cooler).5. Jake brake operation.6. Thermostat.7. DOC inlet...
Detroit DD16 GHG14 (2014-16) Fault Code: SPN 523 FMI 13 (MCM, CPC) Transmission Current Gear Signal Missing
Posted by Diezel Solutions on
NOTE: Please see the step by step troubleshooting procedures for this specific code. PROBABLE CAUSES:1. If any codes related to battery voltage are present, fix those first.2. If 625-9 present, troubleshoot that instead.3. If any engine modules have been programmed recently, check configuration.4. Another computer module on the truck (ABS, transmission, cab, etc…) has a failure that is causing this.
