Audible warnings alert the driver of a system concern or a critical vehicle
condition. The radio or the chime module (export) generates the audible warnings.
If the radio or chime module 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 (180 pulses per minute)
- Medium rate chime (120 pulses per minute)
- Slow rate chime (60 pulses per minute)
- Single chime
DIC Reminder
The DIC reminder is intended to attract the drivers attention to the DIC for
a warning message. Refer to
Driver Information Center (DIC) Description and Operation
for DIC Description and Operation.
Fasten Safety Belt Warning
The BCM activates the fasten safety belt audible warning as determined by the
seat belt switch. The BCM receives a discrete input from the seat belt switch. The
fasten safety belt warning sounds and the fasten safety belt indicator displays when
the following occurs:
| • | The ignition switch transitions to ON. |
| • | The BCM detects that the drivers seat belt is not buckled (signal is low). |
If the seat belt is buckled when the ignition is turned on, the chime does not
sound. If the seat belt is buckled while the chime is sounding, the chime stops. If
the seat belt is unbuckled after the initial transition to ON, the chime does not
sound.
Key-In-Ignition Warning
The BCM activates the key-in-ignition audible warning as requested by the ignition
key alarm switch. The key-in-ignition warning sounds when the following occurs:
| • | The ignition switch is OFF. |
| • | The body control module (BCM) determines that the drivers door is open
(signal is low). |
| • | The BCM determines that the key-in-ignition switch is closed (signal
is low). |
Lights On Warning
The BCM activates the lights on warning as requested by the headlamp dimmer
switch. The lights on warning sounds when the following occurs:
| • | The key is out of the ignition. |
| • | The BCM determines that the drivers door is open (signal is low). |
| • | The BCM determines that the headlamp switch is in the park or head position. |
Turn Signal Reminder
The BCM activates the turn signal warning as requested by either turn signal
switch. The turn signal warning sounds when the following occurs:
| • | The ignition is in RUN. |
| • | The turn signal switch is in either turn position, sensing, within 1 second,
an open to B+ transition in the turn signal control circuit (left or right turn). |
| • | The vehicle has traveled a distance of 1.2 km (0.75 mi)
by counting pulses on the vehicle speed input circuit. |
The BCM turns off the turn signal reminder when either the ignition switch is
turned to the OFF position, or the turn signal switch returns to the OFF position,
sensing within 1 second, no transitions from open to B+ in either of the turn
signal control circuits (left turn or right turn).
