2001 Chevy Malibu has a 3 tone alert beep that I don't recognize, it's not the regular chime for door open or trunk open what is it. Have had no start issues with car and theft lock is flashing

the chime can be from a few systems that may have a fault going on --seat belt female connection -seat weight switch-turn indicator left on - low fuel-door open -air bag -lights left on -etc

spontaneously alerts ??? Warning chimes Warning Devices The warning device system consists of the following:

• Key-in-ignition warning switch
• Door ajar switch
• Driver and passenger safety belt minder switch (integral to the safety belt buckle)
• Vehicle security module

The instrument cluster and the restraints control module (RCM) control the following chimes:

• Safety belt warning (repetitive chime)
• Key-in-ignition warning (repetitive chime)
• Headlamps on warning (repetitive chime)
• Door ajar warning (single tone)
• Air bag warning (repetitive chime) The following 5 distinct chime rates are used to indicate warning:
  
  • safety belt warning is 1 chime per second
  • key-in-ignition warning is 2 chimes per second
  • headlamps on warning is 4 chimes per second
  • door ajar warning is a single chime
  • air bag warning is 5 chimes per second
  • now which of these is your vehicle doing ?

NOTE: The generic electronic module/central timer module (GEM/CTM) is connected to the ISO link and is diagnosed through the data link connector (DLC) with a scan tool.
There are five warning chimes and lamps the GEM/CTM controls: headlamps operating without the ignition on (chime only), door ajar (chime and lamp), key-in-ignition (chime only), driver seat belt warning (chime and lamp), and message center.


Audible Warnings Warning Condition Lamp Duration Audible Duration Audible Output Safety Belt 60 Seconds 6 Seconds Chime, 60/Min. 740 Hz Key In Ignition - Continuous Chime, 120/Min. 740 Hz Headlamps On - Continuous Chime, 240/Min. 740 Hz Door Ajar Continuous 1 Second Single Tone, 1000 Hz Message Center (Tone Request) - 1 Second Single Tone, 1000 Hz
When the is turned to RUN or START from OFF or ACC, the chime will sound for six seconds or until the safety belt is buckled.
The will turn on for 60 seconds or until the driver safety belt is fastened. Both the chime and the lamp turn on at the same time.
If the safety belt is buckled before the ignition switch is turned to RUN or START, from OFF or ACC, neither the chime nor lamp will be activated.
Anytime the is changed to RUN from START while the safety belt warning indicator is activated, the safety belt warning indicator will remain activated until either the timing sequence has been executed or the safety belt is buckled.
When at least one door is ajar and the key is in the RUN position, the door ajar cluster lamp is activated and remains on until all doors are closed. A warning tone will sound once any time the key is in the ignition switch and any door is open.
The key-in-ignition warning will sound when the driver side is opened with the key in the and the in OFF or ACC. It will continue to sound until the key is removed, the is closed, or the is in RUN or START.
The headlamp-on reminder chime will be activated if the headlamps or parking lamps are on, the key is not in the ignition switch, and the driver door is opened.
A single tone will be provided each time a ground signal is received from the message center. A one-second tone will sound for warning indications from the message center. A 100 milli-second tone will sound for each message center button depressed.

these are the things that cause beeping ... trunk open, door open any one of your 4 doors not closed properly will cause the beeping, seatbelt chime, lights on or key in ignition when door is openbut check all your doors

look under floor mat in trunk and you will find a small door above the fuel tank. Open this door and using a slotted screwdriver turn the valve head 90 degrees clockwise or 1/4 turn. Then pump gas pedal 4 times, click your heels and turn ignition key.

The beeps happen when speeding up and passing other car

there is whats called a trunk lock mechanism that is simmaler to what is in you doos to keep them shut there is a plastic tab that keeps the trunk closed the tap has brokern find you local chevy dealer and pick up the trunk latch should not be any more than $30 usd and labor to put it in will run about $50 usd

Usually when th fluid level low light comes on, it is because the fluid is ging to the front calipers to fill the pistons that push the brake pads against the rotors. This is because the pads are worn down and probably need replacing.

As for the 3 beeps, it is not related to the brakes.

if it is 5 beeps, it is the air bag or pretensioner.

When the ignition is cycled (turned off and then on), the air bag indicator will remain lit for six seconds and then go out. If an SRS fault exists, the air bag indicator will then flash the two-digit LFC. The air bag indicator will flash the LFC five times, then it will remain illuminated for the rest of the key cycle. The RCM will also communicate the current and historical DTCs through the data link connector (DLC), using the scan tool. If the air bag indicator does not function, and the system detects a fault condition, the RCM will signal the GEM to activate an audible chime. The chime is a series of five sets of five tone bursts. If the chime is heard, the SRS and the air bag indicator require repair.
