Thanks for choosing Just Answer . I'm Wolfgang here to help!!
Below is my first answer or request for more information. If you do not understand it, or you need more information from me, or need me to go in more detail. Do not rate yet, just reply. Put yourself in my shoes, I can not see, smell, hear, feel or touch your car, nor do I know any history on it. So take into consideration I am doing my best based on what you tell me. Also understand fixing cars often requires sophisticated tools, that you may not own. So even if you can not do what is outlined in my answer, that does not mean my answer is wrong deserving to be rated negative.

Any aftermarket items on the vehicle ?

Customer: replied 9 months ago.
Not that I know of, I'm the second owner of the car.

Ok you cannot check voltages with using output test with scan tool to get voltages at the light connectors. The voltage is pulse width modulated = duty cycle
