Chime


CHIME
The chime function is a tone generator internally contained within the cluster. The chime will only be operational when the M1 fuse is present and the ignition is in the Run/Start position except for the following functions:

Park/Headlamps On Reminder
* The Park or Headlamps are on.
* The ignition is off
* The driver door is open (ajar switch closed to ground).
* This chime will timeout after 3 (three) minutes.

Key-in Ignition
* The key is in the ignition.
* The ignition is off.
* The driver door is open (ajar switch closed to ground).
* This chime continues until the condition changes. The following chime functions are listed in order of priority. If the cluster senses multiple chime situations and the lower priority chime request condition no longer exists, the cluster will ignore the request.

Seat Belt
* The ignition is cycled to the Run/Start position.
* The drivers seat belt is retracted (seat belt switch closed).
* The cluster illuminates the Seat Belt indicator for 6 (six) seconds or stops immediately if the seat belt is buckled.
* The chime sounds for 6 (six) seconds or stops immediately if the seat belt is buckled.

Driver Door Ajar Warning
* The ignition is ON.
* The driver door is open (ajar switch closed to ground).
* No engine RPM message to the cluster. The cluster will not sound the chime if the engine is running.
* The chime will sound until the condition changes or will timeout after 20 (twenty) minutes.

Passenger Door Ajar Warning
* The ignition is ON.
* No engine RPM message to the cluster. The cluster will not sound the chime if the engine is running.
* 3 (three) sets of 2 (two) quick chimes are sounded.

Low Oil Pressure
* When the Oil Pressure Gauge indicates approximately 4 (four) psi and engine RPM is greater than 300 (three hundred).
* The cluster will illuminate the Check Gauges indicator.
* The cluster receives low oil pressure data on the PCI Bus from the PCM.
* The chime will sound until the condition changes.

Engine Temperature
* When the Engine Coolant Temperature gauge indicates 127° C (260 ° F).
* The cluster will illuminate the Check Gauges indicator.
* The cluster receives engine coolant temperature data on the PCI Bus from the PCM,
* A single chime is sounded.

Low Fuel
* When the Fuel Gauge indicates low fuel, approximately between 1/8th remaining and "E".
* The cluster will illuminate the Low Fuel indicator.
* A single chime is sounded.

Battery Voltage
* When the cluster detects a charging system fault condition or system voltage high condition based on PCI Bus data received from the PCM.
* The cluster will illuminate the Check Gauges indicator.
* A single chime is sounded.

High Speed Warning (gulf Coast Vehicles Only)
* When the Speedometer exceeds 120 Km/h.
* The chime will continue to sound until the vehicle speed drops below 120 Km/h.

Turn Signal On
* When the Left or Right turn signal is turned ON continuously for 1.0 mile (U.S. vehicles).
* Turn signal ON continuously for 4.0 kilometers (BUX vehicles).
* Turn signal ON continuously for 1.6 kilometers (Canadian vehicles).
* Vehicle speed is greater than 15 mph (22 Km/h).
* The chime will sound until the turn signal input is deactivated. If the other turn signal input becomes active or the vehicle speed drops below 15 mph (22 Km/h), the distance traveled will be reset.

SKIM (If Equipped)
* When the SKIM indicator is illuminated.
* The cluster receives SKIM data on the PCI Bus from the SKIM module.
* A single chime is sounded.

Park Brake Reminder
* When the Park Brake input is switched to ground and vehicle speed is present at the cluster.
* The cluster will chime 10 (ten) times.

Air bag
* When the Air Bag Warning indicator is illuminated.
* The cluster receives Air Bag data on the PCI Bus from the ACM.
* A single chime is sounded.
