You have a stored trouble code(s). Your vehicle needs to be tested with a scantool to determine cause. If you dont understand what that means, please seek a qualified repairshop or technician who has the proper scan equipment. There are over 1300 different codes that vehicle has that can illuminate the service engine lamp, likely only 1 of them is yours...but you need to know which. DO NOT try and turn off the light! (If anyone says you can disconect the battery and turn it off, dont listen to that lunatic!) the light itself isnt dangerous, and it indicates that the code data is still stored and in memory available to a technician to help determine exact cause of the fault. If you erase the code and turn off the light with a battery disconnect, crucial diagnostic info could be lost that may turn a 10 minute diagnostic into 2 hours or longer...all of which you could reasonably expect to be billed for. Ge tthe car checked and the technican who checks it can turn the light off after repairs are completed.

SOURCE: service engine soon light stays on how do i turn this off?

you will need to take it in for a diagnosis scan. this Will scan for trouble codes that will direct you and your mechanic to the issue at hand. it will also tell you how to fix this issue as well. once this problem is fixed, the light will shut off.

In most cases, it a failed sensor of some sort. most auto zones will scan the ecm for free.

SOURCE: service engine soon/ABS/Trac lights are staying on

Have the ABS codes scanned. This will get you started in the right direction. Possibility is that one or more of the wheel speed sensors is not working or intermittent - could be wiring or connectors on these as well. Another possibility is the EBCM, Electronic Brake Control Module. I believe the EBCM will throw 1216 code in many cases. THese can be rebuilt online for about $150.00.
The more likely problem is the wheel speed sensors. THese are an integral part of the wheel hub. About $100.00 each for the part. About $250.00 each to have them replaced. They can be tested with an AC voltmeter by spinning the wheel. Also, they should read roughly 850 ohms resistance. The ABS codes will tell you which ones are not reporting.

What does the service engine light mean on a 2015 Ford Edge


Service Engine Soon

If the Service Engine Soon indicator light stays lit after you've started the engine, the On Board Diagnostics system (OBD) has detected a malfunction of the vehicle emissions control system. Contact your authorized dealer as soon as possible.
If indicator light is blinking, an engine misfire may be occurring, which could damage your catalytic converter. Drive in a moderate fashion (avoid heavy acceleration and deceleration), and have your vehicle serviced immediately.*
The Service Engine Soon indicator light illuminates when the ignition is first turned on (prior to engine start) in order to test the bulb, as well as indicate whether the vehicle is ready for Inspection/Maintenance (I/M) testing.
Normally, the Service Engine Soon light will stay on until the engine is cranked, then turn itself off if no malfunctions are present. However, if after 15 seconds this light blinks eight times, it means that the vehicle is not ready for I/M testing.Check this link out Gary.

Service engine soon light


A service engine soon light that flashes generally results form an ignition problem with the engine. A service engine soon light that stays on constant results from an emission control system malfunction. A diagnostic scan from the local parts store can determine which emission system is faulty.

My change oil light never goes off even though I had it changed and now my service vehicle soon light is on even though its been running fine


The change oil light needs to be reset after each oil change...some shops are not knowledgeable on how to do this...Your owners manual will instruct you how to reset the oil change light...The service engine soon is a catch all for low fluids and other needs...Be sure to check your oil level again...to clear the service engine soon light, you can disconnect either battery cable for 15 minutes then reconnect...if the service engine stays on...then you need to have your Grand Am checked...Auto Zone does a free diagnostic of check engine light codes...:)

The service engine soon light comes on for many reasons..it could be as simple as CO2 sensor, or it may just be one of the lights that just stays on, ask your local GM garagre to reset the code for you..maybe cost you a couple bucks.

Service engine soon & brake light stays on


the service engine light is prob due to the oxygen sensor being damaged, not replace or you having the catalytic converter taken off---just messing with you. start at auto zone and have then do a free code read then go from there. you should troubleshoot the low fluid level switch for your brake fluid. unplug it and see if the light goes off and if it doesn't jump the two terminals on the harness. oh the car will have to be running. Let me know MrRodneyLong@gmail.com
