SPN1265 FMI4
Engine Oil Burn Valve Solenoid Driver Circuit - Voltage Below Normal or Shorted to Low Source
CODES:
Fault Code: 223
PID(P), SID(S): S85
SPN: 1265
FMI: 4/4
Lamp: Amber
REASON: Low signal voltage detected at the Centinel™ oil control valve circuit.
EFFECT: Centinel system will be inoperational.
Circuit Description:
The engine control module (ECM) uses the Centinel™ oil control valve to regulate the amount of used oil that is removed from the engine and sent to a waste oil tank. Depending on application setup, the oil control valve can also circulate fresh oil into the engine.
Component Location:
The Centinel™ oil control valve is usually located on the left rear of the engine.
Conditions for Running the Diagnostics:
This diagnostic runs when the keyswitch is in the ON position and when the pulse width modulated (PWM) device is getting energized.
Conditions for Setting the Fault Codes:
The Engine Control Module (ECM) detected the Centinel™ oil control valve signal was not at system voltage when the driver was turned ON.
Action Taken When the Fault Code is Active:
• The ECM illuminates the amber CHECK ENGINE lamp immediately when the diagnostic runs and fails.
Conditions for Clearing the Fault Code:
• To validate the repair, perform a keycycle, start the engine and perform the Centinel™ Operational Test using the recommended Cummins® electronic service tool or equivalent.
• The fault code status displayed by the recommended Cummins® electronic service tool or equivalent will change to INACTIVE immediately after the diagnostic runs and passes.
• The ECM will turn off the amber CHECK ENGINE lamp immediately after the diagnostic runs and passes.
• The "Reset All Faults" command in the recommended Cummins® electronic service tool or equivalent can be used to clear active and inactive faults.
Shop Talk:
Possible causes of this fault code include:
-Signal circuit shorted to ground or return.
-A malfunctioning Centinel™ oil control valve solenoid.
