Detroit Diesel

NOTE: Please see the step by step troubleshooting procedures for this specific code. NOTE: If the ACM (Computer module) has been programmed recently, clear code, test drive, and if code doesn’t come back releaes the vehicle. PROBABLE CAUSES:1. Check DEF tank header harness connector/wiring.2. DEF CAN harness.3. Failed DEF tank header. Detroit DD16 GHG14 (2014-16) Fault Code: SPN 3512 FMI 4 (MCM) 3V Sensor Supply Bank 2 Circuit Failed Low Detroit DD16 GHG14 (2014-16) Fault Code: SPN 3512 FMI 3 (MCM) 3V Sensor Supply Bank 1 Circuit Failed High Detroit DD16 GHG14 (2014-16) Fault Code: SPN 3511 FMI 4 (MCM)...

DESCRIPTION:This code sets when the ACM detects that the DOC outlet temperature sensor is greater that the modeled threshold. MONITORED PARAMETER:Diesel Oxidation Catalyst (DOC) temperature outlet temperature sensor. TYPICAL ENABLING CONDITIONS:Aftertreatment 1 hydrocarbon doser data valid but above normal operational range – most server level. MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:Two seconds DASH LAMPS:1. MIL2. CEL ENGINE REACTION:Derate 25% NOTE: If codes 3242-3, 3242-4, 3242-8, 3250-3, 3250-4, or 3250-8 active, fix those first. PROBABLE CAUSES:1. Inspect entire exhaust & fuel system for leaks.2. Inspect all 3 temperature sensors on the DPF/DOC system.3. Inspect fuel line from...

NOTE: Before starting this troubleshooting procedure, please verify if an Advanced Diagnostic (AD) version is available, and continue with that version if available. ADs provide enhanced functionality that increase the accuracy of the troubleshooting process and are preferred over traditional troubleshooting. The ADs are identified in DiagnosticLink by the magic wand icon next to the fault, and the word “Advanced” label in the “Troubleshooting Type” field. DESCRIPTION:This code sets when the exhaust temperature does not increase above the modeled threshold when regeneration is enabled. MONITORED PARAMETER:Diesel Oxidation Catalyst (DOC) outlet temperature sensor. TYPICAL ENABLING CONDITIONS:1. Regeneration enabled.2. 1100 to 2050...

DESCRIPTION:This code sets when the exhaust temperature dos not increase above the modeled threshold when the low temp regeneration is enabled. MONITORED PARAMETER:Diesel oxidation catalyst (DOC) outlet temperature sensor. TYPICAL ENABLING CONDITIONS:1. Low temperature regeneration enabled.2. 1100 to 2050 rpm.3. 100% engine load. MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:20 seconds DASH LAMPS:1. MIL2. CEL ENGINE REACTION:Derate 10% VERIFICATION:Regeneration PROBABLE CAUSES:1. Inspect entire exhaust & fuel system for leaks.2. Inspect all 3 temperature sensors on the DPF/DOC system.3. Inspect fuel line from doser block assy to the doser injection valve for kinks.4. Remove the doser injection valve...

DESCRIPTION:This fault code sets when the intake manifold pressure is lower than expected while the engine is under a load. MONITORED PARAMETER:Intake manifold pressure. TYPICAL ENABLING CONDITIONS:Engine coolant temperature greater than 65°C (149°F). MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:15 seconds DASH LAMPS:1. MIL2. CEL ENGINE REACTION:None VERIFICATION:1. Engine coolant greater than 65°C (149°F).2. Drive at steady highway speed with loaded trailer.3. Engine rpm greater than 1130 for a minimum of five minutes. PROBABLE CAUSES:1. Failed inlet manifold pressure sensor.2. Inlet manifold pressure sensor connector/harness.3. Charge air cooler failure.
