SPN 100 - FMI 1 (Fault Code 415)
SPN100 FMI1
CODES:
Fault Code: 415
PID(P), SID(S): P100
SPN: 100
FMI: 1/1
Lamp: RED
SRT:
REASON: Engine Oil Rifle Pressure - Data Valid But Below Normal Operating Range - Most Severe Level. Oil pressure signal indicates oil pressure is below the engine protection critical limit.
EFFECT: Progressive power derate increasing in severity from time after alert. If the Engine
Protection Shutdown feature is enabled, engine will shut down 30 seconds after the RED STOP lamp starts flashing.
Circuit Description:
The engine control module (ECM) provides a 5-VDC supply to the engine oil pressure sensor on the sensor supply 1 circuit. The ECM also provides a ground on the sensor return circuit. The engine oil pressure sensor provides a signal to the ECM on the engine oil pressure sensor signal circuit. This sensor signal voltage changes based on the pressure in the oil rifle. The ECM will detect a low signal voltage at operating conditions when the oil pressure can be slightly lower. The ECM will detect a high signal voltage during high engine speeds or operating conditions when the oil temperature is low.
If the ECM detects low signal voltage indicating low engine oil pressure, this fault code sets.
Component Location:
Conditions for Running the Diagnostics:
This diagnostic runs continuously when the engine is running.
Conditions for Setting the Fault Codes:
The ECM detects that the engine oil pressure is below the minimum operating limits.
Action Taken When the Fault Code is Active:
• The ECM illuminates the red STOP ENGINE light immediately when the diagnostic runs and fails.
• A torque derate issued by the ECM, limiting the power output of the engine.
Conditions for Clearing the Fault Code:
The ECM will turn off the red STOP ENGINE light and the torque derate will be removed when the oil pressure reading is detected to be within the normal operating range.
Shop Talk:
Verify the ECM calibration is correct. Check the calibration revision history found on QuickServe® Online for applicable fixes to the calibration stored in the ECM. If necessary, calibrate the ECM.
This fault code indicated that low engine oil pressure has been detected by the ECM. Troubleshoot the cause of the low engine oil pressure.

If the ECM detects low signal voltage indicating low engine oil pressure, this fault code sets.
Component Location:
- For ISB CM2150 engines, the engine oil pressure switch is located on the front of the engine on the left (intake) side on the top of the front gear housing.
- For ISC and ISL CM2150 engines, the engine oil pressure sensor is located on the left (intake) side of the engine block below the ECM.
