Unknown warning chime on 2000 Expedition

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 ?

The audible warnings alert the driver of a system concern or a critical vehicle condition. The radio generates the audible warnings through the speaker. The radio receives audible warning requests via the serial data circuit. If the radio receives multiple audible warning requests, the warning with the highest priority sounds first. The following lists the audible warning priority and the pulse rate:
?€¢
Fast rate chime (200 pulses per minute)

?€¢
Medium rate chime (150 pulses per minute)

?€¢
Slow rate chime (50 pulses per minute)

?€¢


Single chime

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.

IF IT WILL RUN WITH STATER FLUID YOU HAVE A FUEL ISSUE. SINCE PUMP SOUNDS DIFFERENT I WOULD START THERE. CHECK FOR VOLUME & PRESSURE ON FUEL RAIL IF IT NOES NOT THEN THE PROBLEM IS IGNITON, CHECK FOR SPARK

Have you noticed if all your lights come. Sometimes if your airbag bulb it burnt it will chime at you.

Many vehicles chime when your not wearing your seat belt this is the only chime I have ever heard in a vehicle while I drive it. If this isn't the reason read your owners manual I'm sure it will tell you there. Hope this helps good luck.

may happen when the system senses some weight on the passenger seat (dog, etc) or the weight switch is faulty/stuck. You can verify if this is the reason if the passenger airbag notice light shows ON.

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.

key chime sounds if the little tab is grounded where the key contacts it. The theft light is supposed to blink when the system is armed to let you know it is armed. That's normal.

What do you mean by auto door locks won't unlock? The remote doesn't work? the door lock/unlock button on the door trim panel? Do they lock ok? Or, just unlock doesn't work?

• All Windows Operate With the Ignition in the OFF Position

• Circuitry.
• Accessory delay relay.

• CHECK the accessory delay relay; REFER to Component Test. If OK, REPAIR circuit 400 (LB/BK). If not OK, REPLACE the accessory delay relay. TEST the system for normal operation.
