Cummins X15 CM2450 X124B (2018 & Newer) Fault Code: 2368 PID: S82 SPN: 1112 FMI: 3/3 Engine Brake Actuator Driver 3 Circuit – Voltage Above Normal or Shorted to High Source
Posted by PerDiezel Solutions on
Lamp:Amber Reason:Open circuit or high voltage detected at the engine brake solenoid number 3 signal circuit. Effect:Possible reduce engine braking performance. Circuit Description:The Engine Control Module (ECM) controls engine braking on cylinders 1 and 2 by sending a signal to engine brake solenoid 1. The ECM controls engine braking on cylinders 3 and 4 by sending a signal to engine brake solenoid number 2. The ECM controls engine braking on cylinders 5 and 6 by sending a signal to engine brake solenoid 3. Component Location:The engine brake solenoids are located under the valve cover. The engine brake solenoids are controlled...
Cummins X15 CM2450 X124B (2018 & Newer) Fault Code: 2372 PID: PID 95 SPN: 95 FMI: 16 Fuel Filter Differential Pressure- Data Valid But Above Normal Operating Range- Moderately Severe Level

Circuit DescriptionThe engine control module (ECM) monitors engine operating conditions, including the reading of fuel rail pressure, and changes the flow command to either increase (OPEN the fuel pump actuator) or decrease (CLOSE the fuel pump actuator) the fuel supply to the high-pressure pump. Component LocationThere are two fuel filters and several original equipment manufacturer (OEM) supplied components that can impact this fault code. The pressure-side fuel filter is typically mounted directly to the engine, but can also be remote mounted. The suction-side fuel filters and other OEM supplied components are OEM specific. The OEM is required to supply a...
Cummins X15 CM2450 X124B (2018 & Newer) Fault Code: 2373 PID: PID 131 SPN: 1209 FMI: 3 Exhaust Gas Pressure Sensor Circuit- Voltage Above Normal or Shorted to High Source
Posted by PerDiezel Solutions on
Circuit DescriptionThe exhaust gas pressure sensor is used to measure exhaust gas pressure in the exhaust manifold. This information is used by the engine control module (ECM) to control emissions and exhaust gas recirculation (EGR) valve operation. The ECM provides a 5 volt supply to the exhaust gas pressure sensor on the sensor supply circuit. The ECM also provides a ground on the sensor return circuit. The exhaust gas pressure sensor provides a signal to the ECM on the exhaust gas pressure sensor signal circuit. This sensor signal voltage changes, based on the pressure in the exhaust manifold. Component LocationThe...

Cummins X15 CM2450 X124B (2018 & Newer) Fault Code: 2375 PID: PID 412 SPN: 412 FMI: 3 Exhaust Gas Recirculation Temperature Sensor Circuit- Voltage Above Normal or Shorted to High Source
Posted by PerDiezel Solutions on
Circuit DescriptionThe exhaust gas recirculation (EGR) temperature sensor is a variable resistor sensor and is used to measure the temperature of the EGR gas flow after it exits the EGR cooler. The engine control module (ECM) supplies 5 volts to the EGR temperature signal circuit. The ECM monitors the change in voltage caused by changes in the resistance of the sensor to determine the EGR flow temperature. The EGR temperature value is used by the ECM for the engine protection system and engine emissions control. Component LocationThe EGR temperature sensor is located on the EGR connection tube between the EGR...
