Diagnostic Trouble Codes for the 5 VDC Sensor Supply Circuit    
J1939 Code    Description    Notes    
3509-3     Sensor Supply Voltage 1 : Voltage Above Normal     The Electronic Control Module (ECM) detects the following conditions:
The 5 VDC supply for the sensors is greater than 5.16 VDC for more than one second.
The ECM has been powered for at least 3 seconds.
Diagnostic code 168-4 is not active.
The warning lamp will come on. The ECM sets all of the sensors on the 5 VDC circuit to the default values.
The engine will be derated.    
3510-3     Sensor Supply Voltage 2 : Voltage Above Normal    
3509-4     Sensor Supply Voltage 1 : Voltage Below Normal     The ECM detects the following conditions:
The 5 VDC supply for the sensors is less than 4.84 VDC for more than one second.
The ECM has been powered for at least 3 seconds.
Diagnostic code 168-4 is not active.
The warning lamp will come on. The ECM sets all of the sensors on the 5 VDC circuit to the default values.
The engine will be derated.    
3510-4     Sensor Supply Voltage 2 : Voltage Below Normal    
100-21     Engine Oil Pressure : Data Drifted Low     The ECM detects no 5 VDC supply to the engine oil pressure sensor.    
108-21     Barometric Pressure : Data Drifted Low     The ECM detects no 5 VDC supply to the barometric pressure sensor.    
3358-21     Engine Exhaust Gas Recirculation Inlet Pressure : Data Drifted Low     The ECM detects no 5 VDC supply to the Nox Reduction System (NRS) inlet pressure sensor.    
3563-21     Engine Intake Manifold #1 Absolute Pressure : Data Drifted Low     The ECM detects no 5 VDC supply to the intake manifold pressure sensor.    
3609-21     Diesel Particulate Filter Intake Pressure 1 : Data Drifted Low     The ECM detects no 5 VDC supply to the Diesel Particulate Filter (DPF) inlet pressure sensor.    
3837-21     Aftertreatment 1 Secondary Air Pressure : Data Drifted Low     The ECM detects no 5 VDC supply to the Aftertreatment Regeneration Device (ARD) air pressure sensor.    Note: A 3509-XX diagnostic code indicates a fault in the 5 VDC circuit on the J2/P2 connector. A 3510-XX diagnostic code indicates a fault in the 5 VDC circuit on the J1/P1 connector.The following background information is related to this procedure:The ECM supplies regulated +5 VDC to the following sensors on P2:46:
The position sensor for the intake throttle valve
The position sensor for the NRS Valve
Engine oil pressure sensorThe ECM supplies regulated +5 VDC to the following sensors on P2:47:
The NRS inlet pressure sensor
The NRS differential pressure sensor
Fuel rail pressure sensor
Barometric pressure sensor
Intake manifold pressure sensorThe ECM supplies regulated +5 VDC to the following components on P2:45:
The position sensor for the combustion air valve
ARD pilot fuel pressure sensor
ARD air pressure sensor
The DPF inlet pressure sensor
The DPF differential pressure sensor
The inlet temperature sensor for the DPF and the ARD flame detection temperature sensor
The aftertreatment identification moduleThe ECM supplies regulated +5 VDC to the analog throttle position sensors (if equipped) on P1:2.A diagnostic code can be caused by the following conditions:
A short circuit in the harness
A short circuit to a voltage that is higher than 5.16 VDC
A faulty sensor
A faulty ECM
An open circuit in the harness
