Econoline E550 V10-6.8L VIN S (2003)
Audible Warning Device: Description and Operation
Chime/Buzzer
The warning chime/buzzer module produces a repetitive chime or steady buzzing sound, for either a predetermined amount of time or continuously,
under the following conditions:
-
The driver safety belt is unbuckled and the ignition key is in RUN.
-
The key is in the ignition switch lock cylinder and the driver door is open.
-
The headlamp switch is in the HEAD or PARK position, the driver door is open and the key is not in the ignition switch lock cylinder.
Safety Belt warning
The safety belt warning chime/buzzer reminds the driver to fasten the safety belt. This occurs when the ignition key is turned to RUN and the driver
safety belt remains unbuckled. The chime/buzzer can be terminated by buckling the driver safety belt at any time during the 4-8 second chime/buzzer
warning.
The chime/buzzer works in conjunction with the safety belt warning indicator in the instrument cluster. When the ignition key is turned to RUN, the
safety belt warning indicator will illuminate for five seconds, whether or not the driver safety belt is buckled, to carry out a prove out on the bulb.
Key-in-Ignition Warning
The key-in-ignition warning chime/buzzer will sound continuously when the ignition key is in the ignition switch lock cylinder with the key OFF and
the driver door open. The chime/buzzer will continue to sound until the key is removed from the ignition switch lock cylinder or the driver door is
closed.
Headlamps On Warning
On vehicles equipped with headlamps on warning, the warning chime/buzzer will sound continuously when the headlamp switch is in the PARK or
HEAD position, the driver door is open and the key is not in the ignition switch lock cylinder.
The chime/buzzer will continue to sound until the headlamp switch is turned OFF or the driver door is closed.
Belt Minder
NOTE: The belt minder is configurable. To configure without using a diagnostic tool, refer to Belt Minder Deactivating/Activating.
The belt minder feature supplements the current safety belt warning function. The belt minder feature is enabled after the current safety belt warning is
complete. The belt minder reminds the driver that their safety belt is unbuckled by intermittently sounding a chime and illuminating the safety belt
warning lamp in the instrument cluster once the vehicle speed has exceeded three mph. While activated, the belt minder alternates the chime and
indicator from ON for 6 seconds to OFF for 30 seconds.
The belt minder reminder stops when:
-
the driver seat belt is buckled.
-
the ignition is turned to OFF or ACC.
-
five minutes have elapsed since belt minder has started.
