2000 CHEVY MONTE CARLO
3800 V6
SERVICE ENGINE SOON
codes = A SCAN FOUND NO CODES
Repais done prior = ENGINE WAS CLEANED, FRONT HUB ASSEMBLYS WERE
CHANGED.
tip/donation yes
tech = JK
question = THE SERVICE ENGINE SOON LIGHT IS ON, BUT THERE ARE NO
TROUBLE CODES SHOWING UP ON THE SCAN TOOL. I AM THINKING THIS IS THE
REMINDER
TO HAVE THE ROUTINE SERVICE DONE. HOW IS THIS RESET?
JK:
Thank you for the tip/donation.
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?
VISITOR:
It is the "service vehicle soon" message.
Thanks
JK:
There are many different computer systems on todays cars. the service ENGINE indicator
is strickly 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 computers.
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.
VISITOR:
THE RADIO WORKED FINE UNTIL I CHANGED THE BATTERY. NOW IT IS
LOCKED. HOW DO I UNLOCK IT.
JK:
The radio replacement 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.
