2004 F150 battery light and emission light came on and beeped. I pulled over, shut it off and looked in the manual. When I started it again, all was fine,,,no lights.
The problem was there & will come back
So check for codes Generic & Enhanced
Have a shop road test with scanner & look at all data
Go along for the ride
If you just got gas it may be the cap was loose at the
time the evap monitor ran,but there will be a trail most likely
in the PCM (computer) codes & such
A 2004 vehicle most likely has lots of preventative maintenance
that needs to be done,while doing that something will show up on
a scanner,only if you tell a shop what you want done.

check ur fuse relay box it might be out also check ur hot wires make shure they dont have touching the ground
SOURCE: Emission light
map sensor. check your spark plugs, wires, etc. maybe a loose wire plug. did u mention check engine light, i wonder can you tell me what diagnostic code came up. go to ur nearest auto parts if u dont have a scanner. and pull them codes out.
SOURCE: 2004 f150 no tail lights ,left turn signal ,no
Check & clean connector underneath at rear, usually just forward of front bumper, up near frame, drivers side. Does this have a trailer towing plug on it by chance?

There is a great number of things that can cause this **** as an oxygen sensor. or charcole canister, gas cap,or even your catalatic converter you will have to have the car hooked up to a diagnostic computer to find the problem for sure.
hope i helped you
please leave me a rating
Thank you
SOURCE: Check engine indicator light came on
The check engine light comes on when unusual servicing will be required. It could mean any number of things that if left unattended to could severely damage the engine. If you have an auto parts store or dealer that can run a diagnostic I would have it done soon. Some of the auto parts store will perform the diagostic at no cost.
When the service engine soon light (Also called the check engine light or engine management light) is turned on this is to alert you to the fact that Powertrain Control Module (computer) has detected a failure somewhere in the systems it controls you may not feel any difference in the way the engine runs, this can be the transmission or the engine or emission system, there are fault codes set in the modules memory for these faults. What needs to happen now is to have the powertrain control module scanned with a special tool called an OBD2 electronic engine control scanner or a OBD2 code reader. Once the code(s) are read then you must perform the diagnostics for each code and make the appropriate repairs based on the findings of the diagnosis that was performed, this is called doing "Pinpoint" testing.
