Pontiac Repair/Service Vehicle Soon Indicator



My daughter's 2001 Grand Am SEI (3.4) has the Service Vehicle Soon light on.  She's a 6-hour drive away, so I can't readily look at the car myself.
She hasn't noticed any drivability issues and nothing obvious appears to be malfunctioning.

What systems does this feature monitor on this vintage of car?   In other words. what will cause this light to illuminate?   
From what I've researched, this was a relatively new feature in 2001.


ANSWER: Hi Colin:
well with out seeing it it's only a guess. if it just the service vehicle soon and no there are no other lights on and it's not a service engine soon message my best guess would be a burned out head lamp bulb or an issue with the DRL (Daytime Running Lights) usually that is all that light means as long as no other lights are on.  she can stop by one of the big box stores in her area they all scan your car for free with the hope that you buy parts to fix it there. on that car a body control module code of b2600 b2601 is VERT common.

Good luck :-}

Assuming it's a problem with the DRL, can you offer any suggestions as to what to check for (other than a blown DRL fuse).
Perhaps a bad ground somewhere.

Any suggestions as to where to look would be appreciated.

Thanks again,

It all depends. if your not in the rust belt where I live usually it's just a bad bulb you can have her turn the head lights on and then try the hi beams and see if one of the bulbs is out. if the bulb it out more then likely that is all it is. BUT if one of the bulbs is dim you have a wiring issue the forward lamp harness on that car had a few places with splice packs that like to corrode and cause high resistance and the end result is a dim lamp at first then no lamp at all once the corrosion builds to the point it actually breaks the splice or builds up enough that the current can't flow. it's not going to be a blown fuse if that were the case the car would probably not have any head lamps at all.  if indeed it needs a head lamp you need to get the exact same one not a fits all at wal*mart depending on the year the bulb could say a 9004 bulb for example and right around that year they switched to say a 9004 LL bulb don't mix them it will cause issues as well. the resistance of the bulb is different and the car will have headlamps that work but still have an DRL (service vehicle soon) light on because it has the WRONG bulb in it. seen it happen a lot of times... Alos if you change the blubs your self be careful the retainer that holds the bulb in get very brittle fro the heat!
