Keep in mind that two warning there, Check Engine and Service Engine Soon; Check Engine means there is a malfunction... Service Soon is reprogrammable, when you change you oil.

"Check Engine" are refer to the emission codes, but not always. I suggest visit some autozone ot autoshop with scan tools or "reader code" to know exactly what fault code is stored there. With this code number we could send you additional details.

Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day.

SOURCE: The "Service Engine Soon" light

No, because you have to check for codes
whenever you get any OBD 1 or 2 Light on your dash

Then you have some idea of the area of the vehicles
malfunction

Those lights have been with us for 31 years,I guess you
missed out on alot over the years, not keeping up with
cars

WHY is it that my 2011 Jeep Cherokee Won't start (ETC light comes on)

skim
did you read the operators guide, yet, it tells you what the dash lamps mean on all cars made.
ETC ,means, electronic throttle control , that lamp means its BAD.
op man.. page 270
says what/?
it says get it serviced..
http://www.jeep.com/en/owners/manuals/

ill quote that
If the light remains lit with the engine running, your
vehicle will usually be drivable. However, see an authorized
dealer for service as soon as possible. If the light is
flashing when the engine is running, immediate service is
required and you may experience reduced performance,
an elevated/rough idle or engine stall and your vehicle
may require towing
. end quote.

if the question was why is it bad, im a DIY guy,?
then read the FSM, get it and read it and do all steps in the manual.
first you scan the PCM for ETC errors and such.
then do the steps it says for each error.
this path , works on all cars made.
