Cummins X15 CM2450 X124B (2018 & Newer) Fault Code: 235 PID: PID 111 SPN: 111 FMI: 1 Coolant Level- Data Valid But Below Normal Operational Range- Most Severe Level
Posted by PerDiezel Solutions on
Circuit DescriptionThe coolant level sensor is a switch and is used to measure the level of the engine coolant in the radiator top tank. The coolant level sensor is immersed in the coolant and returns a different signal voltage when immersed in coolant versus being out of coolant. The engine control module (ECM) monitors the change in the signal voltage to determine the level of the engine coolant. Component LocationThe engine coolant level sensor is typically located in the radiator top tank or surge tank. Refer to the OEM service manual for the location. Conditions for Running the DiagnosticsThis diagnostic...
Cummins X15 CM2450 X124B (2018 & Newer) Fault Code: 2353 PID: SID 146 SPN: 2791 FMI: 6 EGR valve Control Circuit- Current Above Normal or Grounded Circuit
Posted by PerDiezel Solutions on
Circuit DescriptionThe exhaust gas recirculation (EGR) valve is controlled by a brushless motor located on top of the EGR valve. The EGR valve motor uses three different motor legs to move the valve through its range of motion. The ECM uses the EGR motor A, B, and C wires to command the EGR valve to the appropriate position in order to meet EGR flow targets.The EGR valve motor contains three position sensors that detect the location of the EGR valve. These sensors report the position of the valve back to the ECM over the EGR valve position A, B, and...
Cummins X15 CM2450 X124B (2018 & Newer) Fault Code: 2363 PID: SID 80 SPN: 1073 FMI: 4 Engine Brake Actuator Driver Output 2 Circuit- Voltage Below Normal or Shorted to Low Source

Circuit DescriptionThe engine control module (ECM) controls engine brakes on cylinders 4, 5, and 6 by sending a signal on the engine brake solenoid number 2 signal circuit. If an engine brake is installed, there will be a jumper harness from this connector to the engine brake pass-through connectors on the rocker lever housing. Component LocationThe engine brake solenoids are located under the valve cover. The engine brake solenoids are controlled through the engine harness by the ECM. Conditions for Running the DiagnosticsThis diagnostic runs when the keyswitch is in the ON position and when the pulse width modulated (PWM)...
Cummins X15 CM2450 X124B (2018 & Newer) Fault Code: 2365 PID: S82 SPN: 1112 FMI: 4/4 Engine Brake Actuator Driver Output 3 Circuit – Voltage Below Normal or Shorted to Low Source

Lamp:Amber Reason:Low voltage detected at the engine brake solenoid number 3 signal circuit. Effect:Possible reduced engine 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 through the engine harness...
