The audible warnings alert the driver of a system concern
or a critical vehicle condition. The IPC generates the audible warnings. If
the IPC 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
Fasten Safety Belt Warning
The IPC activates the fasten safety belt audible warning as requested
by the IPC. The IPC receives a low input signal from the seat belt switch
for 8 seconds. The fasten safety belt warning sounds and the
fasten safety belt indicator illuminates when the following
occurs:
| • | The ignition switch transitions to ON. |
| • | The IPC detects that the driver's 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 IPC activates the key-in-ignition audible warning as requested by
the BCM. The BCM sends a class 2 message to the IPC indicating
the chime frequency (medium rate) and duration (continuous). The
key-in-ignition warning sounds when the following occurs:
| • | The ignition switch is OFF. |
| • | The body control module (BCM) determines that the driver's door
is open (signal circuit is low). The IPC receives a class 2 message
from the BCM indicating the door ajar status. |
| • | The BCM determines that the key-in-ignition switch is closed (signal
circuit is low). The IPC receives a class 2 message from the BCM indicating
the key-in-ignition status. |
Lights On Warning
The IPC activates the lights on warning as requested by the body control
module (BCM). The BCM sends a class 2 message to the IPC indicating
the chime frequency (fast rate) and duration (continuous).
The lights on warning sounds when the following occurs:
| • | The BCM determines that the driver's door is open (signal circuit
is low). The IPC receives a class 2 message from the BCM indicating
the door ajar status. |
| • | The IPC determines that the headlamp switch is in the park or
head position. |
Turn Signal Reminder
The IPC activates theturn signal warning as requested by the IPC. The
IPC receives a low input signal from the turn signal switch indicating the
chime frequency (medium rate) and duration (continuos). 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 IPC 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, 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).

on in the IPC:
| • | ACT HNDLG-WARMING UP indicator |
| • | COOLANT OVER TEMP indicator |
| • | LOW OIL PRESSURE indicator |
| • | SERVICE ACTIVE HNDLG indicator |
| • | WARMUP COMPLETE indicator |
