Steps
1
Check engine or service engine soon light on.
Before you spend a lot of money, try this: Remove
your gas cap and re-tighten it, a loose or bad seal
on the gas cap can set an evap code in your cars
ECM or ECU causing a check engine or service
engine soon light to come on.

Reset your car's ECM or PCM. Loosen the negative
terminal on your battery for 2 or 3 minutes, then
reconnect your battery term. This will reset your
car's ECM or PCM, if there is not a serious
problem. If there seems to a problem then check
the engine or service engine light and see if it will
stay off. If the light comes back on, you have other
problems, the next most common cause is a
clogged or inop e.g.r valve.
You can also reset your ECM/ECU after installing
performance parts for it to learn the new parts
otherwise they will not perform 100 percent
correctly.
Another way too reset is open the engine fuse box
and remove the ecm/ecu fuse sometimes its the
main fuse. After resetting start car/truck and let idle
only do not touch anything during a 10 minute idle
period.

The ECU's of today are very sophisticated computer
chips that monitor all the data recorded by the
various sensors in the engine. Not only do they
monitor the engine, they can also make changes
based on the data that was recorded to keep the
engine running at it's maximum possible efficiency.
When a modification is done on one of our cars,
the program that the ECU was running ends up
conflicting with what is now going on in the engine.
This can cause problems especially at idle when
the engine hangs in the dangerously low RPMs or
just stalls out. So instead of waiting for the ECU to
adjust itself, you might need to reset it manually.
5
NOTE: I am not saying this is the only way to reset
the ECU. I understand there are many other ways
but I have found this way to be easiest and, most
importantly, the safest. consult your manual for
proper fuse locations. If you still have your stock
radio, you will need the security code given to you
by your dealer or (hopefully) by the person who
sold you the car.
6
Make sure the car has already been warmed up to
normal operating temperature and is turned off. Pop
the hood and find the fuse box. It will be on the
passenger side next to the battery as you can see in
the first picture. Remove the lid and pull out both
fuses as pictured in the second picture.
7
Leave the fuses out for a few minutes to allow all
the old data to be wiped out. Plug the fuses back
in. It doesn't matter if you plug them in upside
down or whatever they don't have any polarity so
just make sure you plug the right fuse in the right
place and you're all good. Make sure to replace the
fuse box cover as well.
8
Start up the car and let it idle for about 10 minutes.
Don't hit the gas pedal during this time. This time
allows your ECU to make new data based on how
much air it sees coming into. Use this time to reset
your radio stations and clock. After 10 minutes is
up, turn the car off.
9
That's it, you're done. Once you start the car up
again, the ECU should be aware of the changes to
the motor. Have fun!
