These vehicles do not have a routine service light or indicator, nor does it use the service engine
light for that purpose. I assume the scanner is working properly and has been checked on another
vehicle for its function.
To clarify, is this the service ENGINE light, or the service VEHICLE light?
It is the "service vehicle soon" message. Thanks.
There are many different computer systems on todays cars. The service ENGINE indicator is
strictly powertrain computer related. Service VEHICLE codes are stored in the body control
module. The service VEHICLE indicator can be caused by several different systems. Anything from
vehicle lighting, to theft system, to body control module(BCM) to ABS (but usually an ABS light as
well), powertrain non-emissions related codes, or communications problems between any of these
Most inexpensive scanners only read the powertrain computer. In order to read codes that set a
service VEHICLE light, you would need a higher level scanner that can read BCM codes, as well as
ABS and others if needed. About the only thing that can be done without having the BCM scanned
is to be sure to check all fuses.
THE RADIO WORKED FINE UNTIL I CHANGED THE BATTERY. NOW IT IS LOCKED. HOW DO I
With a radio replacement, this may very well be the cause of your service vehicle light. After
replacing a radio, the system must be set up with a dealer scanner. Audio system option, VIN #,
etc, need to be set up in the radio and the BCM. If not done, this will cause several different body
codes, and is most likely the cause of your service vehicle light.
If the radio just displays LOC, then you need a Radio Unlock Code.

Question: I have a 2001 Monte carlo and my interior lights won't cut off unless i
disconnect the battery. It runs my battery down.
I've seen many problems like the one you're having with your car. What's
happening is that the Body Control Module has an internal failure or short and
is keeping certain electrical circuits powered up. You will need to have the
Body Control Module replaced. It is located under the dash on the left side.
You must have this repair performed at a dealership because it will need to be
programmed and set up to your particular vehicle. A regular repair shop
cannot do this.
