Depends on vehicle, some will assume being stolen if battery voltage / amps drop too low and ECU or alarm system disables start / run. This is to prevent alarm being turned off by cutting battery wires. Normally needs a dealer with laptop and software to reset
there are 2 books, the operators guide, read that first.
then if not there, for sure it's in the FSM.(factory srv. man)
all cars made, same answer.
some cars , just uplugging battery for 1hour does this.
others need other tricks, its in the book,,
It sounds like you have a solenoid issue on the starter... If it push starts fine then all your ignition circuits seem ok... If you feel good that there is not any damage when the keys turn the ignition.. I would lean toward correcting the starter problem.. Hope this helps..
Jumpstarting cars with electronic ignition is not a good idea. Your car is also fitted with an immobilizer, hence the alarm going off. Get someone to drive you to a place that sells suitable batteries, and fit the new one. You should be fine.
the alarm may be in "stolen" mode already. what you can do is that you can switch the key into ON position and open the hood, remove the negative terminal from the battery and reconnect after two minutes. this will give the alarm time to reboot and recognized that you have the key to this vehicle.
I had the same problem Grace and even mechanics could not figure it out at first. I called 3 Acura dealers to find answers.
Mine began acting up when a door lock broke and when it broke, the alarm started going off out of the blue.
But.....I want you to know that the drainage of electrical that the alarm drained my battery. Jumpstarted battery and alarm would immediately start back up and drain it again. In the end, it fried my alternator. It was pretty crazy because the radio was going off and on by itself with the alarm blaring and no way to shut it off.
Answer is there is no way to remove the alarm system because it is all integrated in by the factory, Acura dealers told me. Your car thinks it has been broken into once the alarm goes off like that, so keeps doing it. The fix was to insert my key into the driver or passenger door lock and turn the key back and forth 3X. That resets the alarm and stops the whole problem.
