Detroit DD16 GHG14 (2014-16) Fault Code: SPN 157 FMI 17 (MCM) Minimum Rail Pressure Not Achieved While the Engine is Cranking
Posted by PerDiezel Solutions on
DESCRIPTION:Minimum rail pressure for injection not achieved. MONITORED PARAMETER:Fuel rail pressure. TYPICAL ENABLING CONDITIONS:Always enabled MONITOR SEQUENCE:None EXECUTION FREQUENCY:MIL TYPICAL DURATION:1. DD13: 90 seconds of cranking.2. DD15: 60 seconds of cranking.3. DD16: 60 seconds of cranking. DASH LAMPS:MIL ENGINE REACTION:None VERIFICATION:1. Turn the ignition on.2. Clear codes using the diagnostic service tool.3. Start engine.4. Check for codes. Check as follows:The motor control module (MCM) monitors the fuel rail pressure and when fuel rail pressure does not reach a minimum 150 bar with three cranking cycles, the MCM sets the code. One cranking cycle for the DD13 is 30 seconds. One...
Detroit DD16 GHG14 (2014-16) Fault Code: SPN 157 FMI 18 (MCM) Fuel Rail Pressure Too High
Posted by PerDiezel Solutions on
DESCRIPTION:Fuel rail pressure too high. MONITORED PARAMETER:Fuel rail pressure TYPICAL ENABLING CONDITIONS:Closed loop and actual RP greater than 200 bar of desired RP. MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:8 seconds DASH LAMPS:1. MIL2. CEL ENGINE REACTION:Derate 25% VERIFICATION:Steady engine 1400-1500 rpm: Two minutes. NOTE: The motor control module (MCM) monitors the fuel rail pressure, and when fuel rail pressure deviation is greater than 200 bar higher than requested fuel rail pressure for eight seconds, the MCM sets the code. POSSIBLE CAUSES:1. Faulty fuel rail pressure sensor.2. Faulty quantity control valve (QCV).3. Faulty MCM.4. Faulty wiring. NOTE:...
Detroit DD16 GHG14 (2014-16) Fault Code: SPN 158 FMI 2 (CPC) Ignition Switch Status of CPC and MCM Do Not Match

NOTE: Please see the step by step troubleshooting procedures for this specific code. NOTE: If inactive, clear the code, cycle the engine, and see if comes back. If it doesn’t problem solved. Otherwise, possible failures are:1. Measure voltage on the ECM 21-pin connector pin 7 and ground. If less than 11.5 V, repair the wiring to pin 7.2. If 11.5V or greated, find the Common Powertrain Controller connect #2. Measure the voltage between pin 3 and ground. If less than 11.5V, find source of problem.

Detroit DD16 GHG14 (2014-16) Fault Code: SPN 158 FMI 7 (ACM) Battery Power is Disconnected Before Aftertreatment Control Module has Completed the Diesel Exhaust Fluid Key Off Purge Cycle
Posted by PerDiezel Solutions on
DESCRIPTION:This is a silent fault (No DASH LAMPS). NOTE: If fault occurs while engine is running, all power and grounds should be inspected from the batteries to the ACM. NOTE: This is a silent code and will not illuminate the dash light. Disconnect batteries, make sure key is off. Wait 5 minutes, reconnect, and clear the inactive code.
