Car is dead but front signals are blinking

[sachmo133]

I drove my car earlier and wife noticed my front signals were blinking. The doors are unlocked but there is no power in the car at all. Doors will not lock. Will try to jump it when it stops raining. But anyone have any insight?

Sorry it was about 5 hours between me driving the car and my wife seeing the lights.

Really Weird Symptoms result from low or bad batteries in these cars.

If you can jump start it, take your battery to be tested.

My F150 does the same thing when the battery tanks. Checked everything for a ground short or a draw you name it. Ends up just being the truck having a meltdown when the battery drops a cell. Relays lock on and 4 ways just blink until you power down everything.

Yeah dead battery. Jumped it via ford roadside and run it for about 30 minutes and all is fine. I have never had a battery go so dead before.

Sounds like it's time for a couple of things.

First, have the battery condition checked. Any auto parts store will do it for free.

Second, check the car (or have someone do it) for any unusual parasitic draw.

Personally, I wouldn't put those off for too long...

Take the battery out getting it checked then reset the BMS. The BMS must be reset everytime you disconnect the battery to let it know what rate to charge it at. This should fix it.

Yup that's a dead battery! That's actually one of the ways the computer tries to tell you the battery is dead. Mine did the same thing when my battery went. Showed no symptoms of it going bad until it went bad.

I did not know this. I've unhooked my batter quiet a few times & I just reconnect when done.

So it probably wasn't charging correctly

There's your answer. If you do not lock the doors, the car is always active in a state of readiness waiting for the ignition start. If you've been doing this all along since you've had the car, you've been slowly weakening the battery. This time it finally become too weak to function. Always lock your car doors, and always store the key fob away from the car. Keeping the fob within proximity of the car, also puts it in a state of readiness waiting for the unlock signal.

To clarify - the BMS reset tells the system that the battery is new (days in service), not the state of charge. The system calculates the state of charge any time the car is locked and the fob is out of range for 8-10 hours.
