J1939 Code Description Effect and Action
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 the
sensors on the 5 VDC circuit to the default values.
The engine will be derated.

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 the
sensors on the 5 VDC circuit to the default values.
The engine will be derated.

3512-3
Sensor Supply Voltage 4 : Voltage
Above Normal The ECM detects the following conditions:
The 8 VDC supply is more than 8.8 VDC for more than one
second.
The ECM has been powered for more than 3 seconds.
Diagnostic code 168-4 is not active.
The ECM will log the diagnostic code and the warning lamp
will illuminate while this diagnostic code is active.
The engine may be limited to low idle.
Speed/Timing - Test
3512-4
Sensor Supply Voltage 4 : Voltage
Below Normal The ECM detects the following conditions:
The 8 VDC supply is less than 7.2 VDC for more than one
second.
The ECM has been powered for more than 3 seconds.
Diagnostic code 168-4 is not active.
The ECM will log the diagnostic code and the warning lamp
will illuminate while this diagnostic code is active.
The engine may be limited to low idle.
An active diagnostic code may not cause any noticeable
effect on engine response unless the voltage drops below
6.5 VDC.
