Low beam lamp(s) fault detected 2014 kenworth no low beam lights

If the low beam works on one the left side but not the right has to be a wire or bad bulb I am willing to say just looking at the bulb is not always right. and as far as a relay there is not one that I know of.

Some ideas here. It may be an issue in the headlights control module.

Modern digital vehicles use some unconventional circuits so troubleshooting isn't always straightforward and checking the supply to and from the fuse, etc. with a test lamp.

A wiring diagram is necessary for in depth investigation.

If the low beam is the HID type it might be a faulty ignitor. If this type beware of dangerous high voltage.

No such fuse.

No on the fuse . The LH HDLP and RH HDLP fuse in the fuse block - under hood, supply battery positive voltage to both low and high beam lamps at all times. For manual operation, when the headlamp switch is in the ON position, the headlamp switch supplies ground directly to the headlamps and to the body control module (BCM) on the headlamp low or high beam signal circuit, depending on the position of the headlamp dimmer switch. The BCM uses this signal to determine if the conditions are present to illuminate the daytime running lamps or park lamps.
The headlamps may be turned on 2 different ways. First, when the driver places the headlamp switch in the ON position, for manual operation. Second, with the headlamp switch placed in the OFF position activating automatic lamp control (ALC).For ALC operation, the BCM receives a signal from the ambient light sensor indicating a low or high ambient, outside, light level. Under low light conditions the BCM grounds the headlamp relay control circuit energizing the headlamp control relay. The now closed relay supplies ground through the headlamp switch to the headlamps and the BCM on the headlamp low or high beam signal circuit, depending on the position of the headlamp dimmer switch. When the BCM grounds the headlamp relay control circuit it also grounds the park lamp relay control circuit illuminating the park lamps. The headlamp relay is grounded at G203.
Daytime Running Lamps (DRL)
The low beam headlamps operate at reduced intensity when in daytime running lamps (DRL) mode. The ground circuit to the switch side of the DRL relay has a resistor in-line to reduce the intensity of the low beam headlamps for DRL operation. The body control module (BCM) receives a signal from the ambient light sensor indicating a low or high ambient, outside, light level. Under daylight conditions the BCM grounds the DRL relay control circuit energizing the DRL control relay. The now closed relay supplies ground directly to the low beam headlamps and to the BCM on the headlamp low beam signal circuit. The low beam headlamps now illuminate with reduced intensity. The DRL relay is grounded at G203. Any time the headlamps are illuminated the DRL will not illuminate. Manual park lamps do not effect DRL operation.

I would check for the groundwire continuity

Check you fuse panel

It can be faulty low beam lamp or its connection issue for low beam lamps.

There are few solved helps links with proper solution to troubleshoot these issues.I suggest you to refer the links below.Click the link:----

it has command start ???? Is this some kind of aftermarket add on ? This shouldn't have anything to do with the running lamps . unless someone hooked something up in correctly . Does the car have DRL - day time running lamps ? The Daytime Running Lamps (DRL) control module is designed to automatically operate exterior lights depending on outside light conditions.
The DRL control module operates in 2 modes:
• The day mode
In the day mode, the DRL control module turns ON the high beam headlamps at a reduced intensity when the DRL ambient light sensor detects daylight under the following conditions:
- The ignition switch is in the RUN position.
- The headlamps are OFF.
- The park brake is OFF (released).
• The low light mode
In the low light mode, the DRL ambient light sensor detects darkness, turning OFF the high beam headlamps and turning ON the low beam headlamps through circuit 10.
Additionally, the DRL ambient light sensor turns ON the following lamps through circuit 9:
- The park lamps
- The sidemarker lamps
- The license lamps
- The tail lamps
