2000 Ford F250 SD V10 has an alert chime that upon starting up the motor beeps three times pauses, then repeats. Does this maybe 5 times then stops. What is the problem or alert about. No idiot lights light up on dash, just the tone sounds.

There is no fuse just for door ajar chime.

Spray your Locks with PB Blaster or WD 40

The warning chime of 5x5 is a sign that the SRS ( airbag ) light is burnt out, and there is an error with the SRS system.

Verify SRS ( airbag ) lamp operation, turn the key from off to run ( do not start ) the airbag lamp should illuminate. If not, it is burnt out. Need to pull the cluster and replace.
( thread at F150online.com on cluster removal in the how to forum - titled about changing cluster illumination color or installing a cluster overlay ).

Once you replace the SRS bulb, you will get a LFC ( light Flash Code ) of a 2 digit number.
Example :
flash flash flash flash { short pause } flash flash { longer pause } flash repeats the same for 5 times, the solid on.
This is an example of a LFC 4-2. Once you have the LFC start a new problem with the LFC and we can get that fixed after you get the bulb replaced.

Try not using the programmer, and see if the issue
resolves itself. Proccess of Elimination. Good luck.

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.

does the airbag light come on when you start vehicle? If the lamp is out it will give an audible beep.

Is your airbag light on or not working? does your seatbelt light work? do you wear your seatbelt? This type of chime usually indicates a problem in the SRS system. (safety restraint system) Assuming 5 chime pause 5 chime pause and continues for 5 cycles and then stops.

Here are the warnings:

The generic electronic module (GEM) controls the following warnings and chimes:

• Driver safety belt not fastened (warning lamp and repetitive chime).
• Key-in-ignition (repetitive chime).
• Headlamp-on warning (repetitive chime).
• Door ajar (warning lamp and single tone).

The following four distinct chime rates are used to indicate warning:

• Seat belt warning chime is one chime per second.
• Key-in-ignition warning is two chimes per second.
• Headlamp-on warning is four chimes per second.
• Door ajar warning is a single chime.

please rate as solved if this is what you needed.
