Mitsubishi Galant Alarm Problem

for sure not just a bad horn button or its relay
when it alarms does the dash screen show door errors>?
it is not a single system it is deeply integrated in to all.
do not fool around air bags, or boom, they must be disabled first working near any air bag SRS



I FEEL YOUR PAIN, MOST OEM ALARMS CAN NOT BE FULLY DISABLED (AS IN FOR EVER , HACKED?)
IS THE CAR BATTERY FULLY CHARGED, NOT WEAK?
ONE SOLUTION IS TO ASK THE DEALER TO DISABLE IT
OR PULL THE HORN FUSE f8.. JUST TO GET SILENCE
I AM NOT TALKING IMMOBLIZER HERE. JUST THE DOOR ALARMS.

SCAN THE PCM FIRST (IT MAY TELL YOU WHICH DOOR FAILS)
THERE ARE 10+ SWITCHES TO FAIL HERE THIS YEAR.
FRONT AND REAR./
DOORS CAN BE SOME TIMES
MY CAR THE USER GUIDE TELLS YOU HOW. TO NOT SET ALARMS.
ON SOME CARS JUST USE THE METAL KEY TO LOCK THE DOOR AND AND ALARMS ARE NOT ENABLED, RTM READ YOUR USERS GUIDE FIRST
YES SOME CARS THE SILLY ALARM DOES NOT TELL YOU WHICH DOOR SWITCH FAILS ,JUST THAT 1 IN 10 DID. 1 FOR LIFT GLASS
YES A HUGE PAIN REPLACE ALL SWITCHES 1 BY 1./
BUT IF MUST GUESS TRY DRIVES DOOR SW FIRST, IT GETS HARD USE.

FIRST MAKE SURE FOBS ARE NOT BAD GOING TO PINIC MODE
TO DO SO, TAKE OUT FOB BATTERY
OR WRAP THE FOB IN KITCHEN ALUM FOIL.
OR FIND STEEL COOKIE BOX AND PUT ALL FOBS IN THE CAN
THIS FORMS A FARADAY GAGE
ALSO A FOB BAD OR ITS BATTERY WEAK CAN BE IT.
SO GO TO BED WITH FOBS ALL IN A TIN BOX. SEE IF IT ENDS PAIN.

MANY CARS THE USERS GUIDE EVEN HAS SPECIAL MODES
LIKE NO HEAD LAMP FLASHING EVER,(BY ARMED OR ALARM)

JUST HAD 1 FOB HERE THAT WENT BERSERK
OPENS TAIL GATE GLASS A 1000 TIMES AS WE SLEEP!
AND DOING SO BATTERY NEW FAILS FAST. GOES WORSE.
THE BUTTON IN THE FOB IS SHORTED AND CAN NOT BE REPAIRED.
ONLY A NEW FOB.



CHAPTER 3 IN YOUR MANUAL STATE( AND IS NOT CLEAR)
USERS GUIDES ARE WRITTEN BY KLINGONS.
Alarm deactivation The alarm can be deactivated in the following ways.
By using the remote control transmitter to lock or unlock
the door or to open the trunk lid.
Turn the ignition key to the "ON" position.

Disarmed stage The system will be disarmed when either of the following steps
are taken:
1. All doors are unlocked by the remote control transmitter.
2. The ignition key is turned to the "ACC" or "ON" position.
3. If the UNLOCK button is pressed when all doors are
closed and no door is opened within approximately 30
seconds, re-arming will automatically occuR.

I'D ASK THE DEALER FOR HELP. OR ANY ASE SHOP TOO.
IF THE SCANS TELL WHAT FAILED WHY WOULD YOU WANT TO MISS THAT?

on my car locking the door with key only , alarms are not active. finding this out on mitsubishi is not easy.
some galant's have hood switch and if bad or not aligned
boom
justanswers said

The only methods to disarm the factory alarm is to either use the wireless remote to unlock the doors while the alarm is going off, or use the key to unlock the car twice, either using the drivers door or the trunk lock.

There is no other disarming procedure. If the lock cylinders do not disarm it, it is possible that both of your cylinder switches are bad.



recap (my hit list) list shorter.
check all fuses
battery main in car 12vdc not weak 12.6v is good or more.
car starts can drives far ,day or night?
horn button not bad, or clock spring shorts, steering col.
keyfobs not bad, (remove all coins for testing) this test assumes the fobs are super bad and must be defeated. now.

see if dash message shows,:door open alarm) <<< 11 switches to fail.
scan the PCM to see DTC related to doors or alarm or horn.
use the metal key to lock door, and not set alarm.
some dealers can disable some features here, ask them.

see next answer base on dead fobs or those gone mad.
consider fob buttons can short and is never fun this. ever.
consider drowned fob (wet inside,) battery out now.

one more from justanswers
lost fobs, or dead ones totally dead/bad or mad.

Then to disarm you will insert the key into the drivers door and turn it twice to unlock. Either the drivers door or the trunk lock can be used for this.

You can not simply disconnect the alarm on this model. The alarm is built into the ETACS (Electronic Timing and Alarm Control System). To disable the ETACS you would lose functionality of your locks, dome light, turn signals, low beam headlights and windshield wiper control. All of these functions are built into the ETACS with the alarm function.
and more....

the dash lamp marked SECURITY IS DEAD all the time.keyon and off? fuse #2 missing,(security fuse)?
remove the remote battery so the bad buttons in FOB do not trip the alarm
I',m sure you mean factory alarm is in the car.
in USA we can scan the OBD2 port and see why any alarm tripped.
lots of ways there are, door switches, etc.
lost the users manual tell you on most cars the alarm need be enabled. and how.
most say , open the door with good fob.
then do not lock the door using fob and alarm is not active.
but with a dead fob how? (car came new with 2 fobs) lost 2nd?
my answers are for USA spec cars only, not world wide. ever.

doors with keyless entry system is what they call this.
fob locks. simple
have you examined the whole car for wiriing harness hacks that put in any kind of 1000 aftermarket alarms here, this is first.
is the horn honking? the same horn the steering well uses
or some other horn hacked in to car. ( we inspect all this first)

the factory ETACS as its own fob RECEIVE inside (antanna)
there are 3 fuses to ETACS.
fuse 22 do not pull that it kills vast other things too.
Fuse 2 and fuse 15 goes there but not sure what happens pulled
but seems the interior door lock buttons go dead. doing that..

here is my only cure.
pull the battery NEG lug for 1hour, or more even overnight
see if ETACS , resets (well it sure will) but do so and not go into alarm and first remove the FOB battery (on all fobs for this car)


see fob guts below
1 coin cell there , remove it,
now bad buttons do not cause system to fail.
open doors only with metal key.
all instructions for this car assume the below is not bad.
and buttons love to fail even SHORTED.(BAD)

Disabling the anti theft system isn't that easy! If it was more cars would get stolen! Take the car to a good auto electrician or an alarm specialist they might be able to sort you a replacement remote. If it was a factory fit alarm contact a dealership and ask them what they could do.

If you have an after market alarm sys. take it back to who ever installed it . as far as the key & lock sys . spray some WD40 into the lock and try again . disconect the alarm speaker until you figure it out . Good Luck

You need to find the remote. Once you do,you can use it to turn off the alarm by pressing the unlock button. You can also try pressing the unlock button on the door panel but, I don't know if that will work. You might have to have another remote programed for the vehicle. You can also try putting the key in the door lock and unlocking it.

it depend upon the program of the alarm system.the mitsubishi alarm system is programble or u can check the alarm system control under the steering column and check the central lock controller,the main actuator on the front driver side door

might try locking and unlocking the doors with the key

If ithe alarm is factory when they will have to reset the alarm module with a scanner. If the alarm if aftermarket go to the control module and see if it has a reset button. FOBs (remote) can reset alarm. You Jeep is always set for break-in mode. The FOB sets this when ever the FOB is used to lock the doors. May be bad alarm module - Sorry - Good luck

My ex girlfriend had a factory installed honda remote strt on her vehicle. It was activated by hitting the lock button two times in succession. Some vehicles use a combination of the lock-unlock buttons. try using some combinations on the remote, many "oem" remote starts are installed by aftermarket installers so who knows what they did as a start function, it could also have been changed by the previous owner.
