Have an 09 F150, the headlights will flash on when turned on but instantly go out, if you put the high beams on they remain on.
also, the brake abs warning light pops on, immidiate following the trac control, then read out low tire pressure fault. Thought hub sensor issue, seperate from head lights, until the door ajar started coming on when the brake/trac/tire pressure indicator warnings go out.
To add to the confusion, the change oil soon warnings came on, stays on indicating 4% oil life remaining, note oil just changed.
Not sure what to think, isolated issues, relay going out, insterment panal failing, computer failing?
Truck runs n drives fine. Appointment to take it in Monday, just wanted some input to sleep at night and possibly pass to tech, who is dumb founded per our phone convo.

 

Theres probably 2 low beam fuses, what happens if you remove one at a time and then turn on the low beams?

For the other nonsense, if this was mine i'd try removing the negative battery cable for about a 1/2 hour & see what happens. Maybe the GEM/generic electronic module just needs a good dope slap.

 

I'm with you. I've had multiple lights come on and both times the fix was simple. This was on my Toyota, but it's indicative of these newer cars with "integrated" systems. One time was a brake light fuse. The other time, I just did the old "remove the battery cable" trick. I will say, though, that the lights weren't intermittent. Intermittent electrical problems would seem to be related to flaky wiring/connectors/contacts, but you never know.

I would check all the fuses. I would even go so far as to remove and insert the fuse or to clean up the spades (or whatever they're called) so you have good contact. Corrosion builds up over time.

Also, I would look at the grounds. A bad or broken ground can cause some strange behavior. I just witnessed this personally with the Mountaineer I just bought. And, if there's a diode in the relay or fuse box, check that, too.

These things are quick, simple and cheap to do. It may not fix anything, but at least you've ruled out the simple stuff. Whenever strange things happen, the tendency is to think that it must be something complicated. Been burned more than once (shame on me).

 

Took it in this am, been in service bay since 9am. No word except tech this am stumped given the intermittent issue. Wondering if the console itself might be shorting out or ready to go...
Lucky it's on the dealers dime....Given. length of time I've had it it's all one them. I looked at fuses and some connections but everythig checked out.
IDK. but I got work to do and need my truck. As my dad use to say "A plumber without a wrench ain't no good..." lol

 

How old is the battery in the truck? If over 3 years old and you plan to keep the truck, I'd suggest changing the battery and making sure the cables are clean before reinstalling, then make sure they are secure once connected. With the possible exception of the high beams working reliably, I could understand an old battery in a modern vehicle causing all the issues except the high beams working reliably and the oil change due indication. But even if a new battery were to fix a few of the issues, that's a step in the right direction.

As for the oil change indicator, just changing the oil will not reset the indicator. There's a very specific method to reset the oil change indicator. Was that reset?

Good luck!

The dealership deemed it catastrophic electrical system failure. In the process of a buy back and then it's off to the scrap yard...
Glad it came with a dealer warranty from a dealer willing to stand by thier word, rare indeed...

 

Wow, no kidding!
