my service vehichle soon light has been coming on and off for the past month.. there for a minute it stayed off but just recently it started coming back on again.. I noticed when it comes on I start feeling a slight vibrating in the gas pedal when accelerating... what could this be? I need to know if it's something serious or something simple that would throw this light on. It's not the check engine light... could I need a tune up?

Can you take a picture of the light and post it on here?Also if it's causing issues when it's on I would scan it for codes and let me know the exact code numbers not code descriptions?

"Service Vehicle Soon" is for codes in the Body Control Module, not the engine. You need a professional scan tool to access the BCM. The codes will start with a "B"

Okay but what is the body control module and could it be something simple to fix?

The Body module controls the body functions of the car, unrelated to the engine. You need a professional scan tool as i already stated to find out what the issue is.

Without the codes from the computer you would have to just guess why the light is coming on.There is a great number of things that it could be.Unfortunately the newer the car the more computers and the more possibilities as to why a warning light comes on You need a professional scan that can read all the engine computers.Also write down the exact code numbers not code descriptions.You might also need that professional scan took to help diagnose the car.
