2001 Oldsmobile Alero.
Why does my service vehicle soon come on?
I have a problem with my 2001 Oldsmobile Alero. I recently had the service vehicle soon light
come on. So i look in the booklet that came with it and was wondering if it was the Automatic
Lighting Control and how to fix it. Only the Daytime Running light are working and i have no
nighttime light.

I would greatly appreciate this Thank you.

The Service Vehicle Soon light can come on for several reasons. A problem in the
ABS system
which will usually cause a Traction system light, A communication problem between the BCM and
another computer, or in the interior or exterior lighting systems.

If you are describing that the automatic headlights do not work, or the headlights do not work
from the headlight switch, then the first thing to do as always is to check ALL fuses. The Service
Vehicle light can come on for something as simple as a
blown fuse, headlight bulb(s) burned out,
or can get more involved as a problem with the ambient light sensor for the auto headlamps.
