Find out what the code is and go from there? Auto zone offers a free code read Wink
So get it done and post the results up here.

SVS Light can only be read by a Tech II or similar device it is a BCM code not PCM so autozone cant help


I was told that if you place the car in on but not running and firm and slowly press the gas down to the floor three times in a 10sec time it will reset.

Depends on what it is, if the problem is still there it will not reset it because the BCM will still see the problem once the car starts

That's how you reset the oil life monitor, and it's three times in five seconds.

You need to take it to a place with a higher end scanner (not Autozone or something) to see what is wrong.

My daughter's 2000 Impala (3.4L) developed the same issue recently. No codes came up when scan tool was hooked up.

Two things:

I've read talk of it being a fault within the lighting circuit, but no light issues exist that I know of.

However, the owner's manual says: "SERVICE VEHICLE SOON - This message will come on if you have engine problems. These problems may not be obvious and may not affect vehicle performance or durability..."

A co-worker emissions tech says he recalls seeing this happen twice, with no codes. He ended up selecting 'erase codes' anyways, and it fixed the problem. Going to do the same on hers and see if I too have success.

It could be soooo many things. Have it scanned by someone with a tech II.

A bad fog light relay caused a SVS light in my car a while back..

You guys all have poor information. The MIL (Check Engine) by law can only be illuminated for events which cause, caused or can cause emissions to rise above a 150% threshold of acceptable limits. Because of this, manufacturers have to make their own additional lamps to notify drivers of other improper operating conditions. The Service Vehicle Soon lamp, and other lamps in other cars, will illuminate for other non-ABS and non-SRS faults, including communications problems, circuit failures and thousands of other operational issues. Not all codes or conditions will illuminate a lamp. Clearing codes without performing a repair or verifying conditions to set a code is not advised and can lead to great frustration.

If you don't know what you're doing, take your car to someone who does. Buying yourself a scantool won't make you a technician. Neither will a repair manual. But it'll help more than asking, "How do I turn off this light?"

If everything is fixed, I've found it'll go out by itself. Something's still wrong is my guess.

Take it to Autozone or Weaver or NAPA or O"Reilley's OR..., and get the code read and decipher:

And fix the problem.

If it was an SVS light, your local parts house won't be able to help you. You need a high quality scanner to read those codes.

If it's a light on my dash that says "Service Engine Soon", I would take it wherever the heck I could to read why the computer is upset, and diagnose the problem myself.

Better? Smile

Service Vehicle Codes need to be read by a tech 2 tool which not everyone has. I have been battling with this issue for a few years now. I never got the code read, as I do not want to pay a diagnostic fee but I have read about the issue. There is a short with the light sensor which in turn causes the BCM to fault. I dug this up in a TSB somewhere, wish I had the link.

I am replacing my BCM tomorrow. In the TSB it states the older BCM's were outdated and the newer revisions solved the issue. I could be completely wrong but my car is doing the following:
Service Vehicle Soon light coming on and off with or without the engine running
Security light coming on and off occasionally
Traction Control coming on occasionally after putting the car in gear
Anti lock breaks coming on occasionally

All of those are controlled by the BCM (I believe). If anyone cares I will post a response after it is replaced tomorrow.

Edit: So I got the new/reman BCM and came home, thought I would put it in and do the relearn to see what happens. Got it put in and no longer have the service vehicle soon light so I know it was a bad bcm. I could not get the car to learn the new BCM though with my key so it will have to be programmed. I red where some people were able to do the relearn procedure and it worked fine, so thought it was worth a shot.

No big deal, I am taking it to a shop where they have the tech 2 tool and can do the reprogramming.
