Detroit DD16 GHG14 (2014-16) Fault Code: SPN 1659 FMI 1 (MCM) Thermostat Monitor Error Detected
Posted by PerDiezel Solutions on
DESCRIPTION:Thermostat error detected. MONITORED PARAMETER:Coolant inlet temperature sensor. TYPICAL ENABLING CONDITIONS:Always enabled MONITOR SEQUENCE:None EXECUTION FREQUENCY:Once per drive cycle. TYPICAL DURATION:30 DASH LAMPS:MIL VERIFICATION:1. Allow engine to cool down such that coolant inlet temperature is less than 50°C (122°F).2. Drive vehicle for 30 minutes.3. Preferably with a trailer (loaded or unloaded).4. Do not idle engine except when necessary. NOTE: If any other cooling system codes, fix those first. PROBABLE CAUSES:1. Engine cooling system thermostat.2. Inlet and/or outlet coolant temperature sensor.3. Inlet and/or outlet coolant temperature sensor harness/connector.

Detroit DD16 GHG14 (2014-16) Fault Code: SPN 1663 FMI 7 (MCM, CPC, ACM) Optimized Idle Safety Loop Faulted
Posted by PerDiezel Solutions on
DESCRIPTION:Optimized idle safety loop faulted. MONITORED PARAMETER:Optimized idle safety loop (parking brake, hood tilt switch, neutral safety switch and vehicle speed). TYPICAL ENABLING CONDITIONS:Fault is set active is a maximum number of vehicle speed sensor pulses during and optimized idle engine start is exceeded or the vehicle speed is above 0.25 km/h or the engine torque is above a calibrated threshold for 2 seconds. MONITOR SEQUENCE:None DASH LAMPS:CEL ENGINE REACTION:None VERIFICATION:Run an optimized idle mode. NOTE: Vehicle speed sensor failure.
