Chevrolet Equinox Service Manual: Audible Warnings Description and Operation Gauges

Chevrolet Equinox Service Manual / Body / Driver Info & Control / Audible Warnings Description and Operation Gauges

The audible warnings alert the driver of a system concern or a critical vehicle condition.The radio generates the audible warnings through the speakers. The radio receivesaudible warning requests via the serial data circuit. If the radio receives multipleaudible warning requests, the warning with the highest priority sounds first. On vehicleswithout a radio, a chime module generates the audible warnings and receives audiblewarningrequests via the serial data circuit. Either the radio or the chime module is thechime producer. The following lists the audible warning sounds:

Single pulse gongMultiple pulse gongSingle pulse beepMultiple pulse beepClickClackFasten Safety Belt Warning

The radio activates the fasten safety belt audible warning as requested by the sensingdiagnosing module (SDM). The SDM sends a serial data message to the radio indicatingthe chime as a multiple gong. The fasten safety belt warning sounds and the fastensafety belt indicator illuminates when the following occurs:

The ignition switch transitions to ON.The inflatable restraint sensing and diagnostic module (SDM) detects that the driversseat belt is not buckled and the signal is low. The SDM sends a serial data messageto the instrument cluster indicating the driver seat belt status.

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 seatbelt is unbuckled after the initial transition to ON, the chime does not sound.

Lights On Warning

The chime producer activates the lights on warning as requested by the BCM. The BCMsends a serial data message to the chime producer indicating the chime as a multiplegong. The lights on warning sounds when the following occurs:

The ignition is OFF.The BCM determines that the driver door is open and the signal circuit is low.The BCM determines that the headlamp switch is in the park or head position.Brake Warning

The chime producer activates the brake audible warning as requested by multiple controlmodules. The BCM, electronic brake control module or the parking brake control modulesends a serial data message to the chime producer indicating the chime as a multiplegong. The brake warning sounds and the BRAKE indicator illuminates when the followingoccurs:

The ignition is ON.The vehicle speed is greater than 8-km/h (4.9-MPH). The instrument cluster receivesa serial data message from the engine control module (ECM) indicating the vehiclespeed.The BCM determines that the parking brake is engaged and the signal circuit is low.The brake fluid is low.Key-In-Ignition Warning

The chime producer activates the key-in-ignition audible warning as requested by theBCM. The BCM sends a serial data message to the chime producer indicating the chimeas a multiple gong. The key-in-ignition warning sounds when the following occurs:

The ignition switch is OFF.The BCM determines that the driver door is open and the signal circuit is low.Door Ajar Warning

The chime producer activates the door ajar audible warning as requested by the BCM.The BCM sends a serial data message to the chime producer indicating the chime frequencyof a medium rate and continuous duration. The door ajar warning sounds and the appropriatedoor ajar indicator illuminates in the driver information center when the followingoccurs:

The BCM determines that a door (driver door, passenger door, left rear door, rightrear door) is open and the signal circuit is low. The instrument cluster also receivesa serial data message from the BCM indicating the door ajar status.The vehicle is not in PARK. The BCM receives a serial data message from the ECM/BCMindicating the gear position.Object Detection

The chime producer activates the object detection audible warning as requested bythe object alarm module. When an object is within the measuring range of the sensor,the ultrasonic pulse is reflected and is received by the sending or a neighboringsensor. The sensor converts this signal into a voltage signal and sends this signalto the object alarm module. The object alarm module evaluates the received sensorsignals. As soon as anobject is within the measuring range, the object alarm module sends a message viaCAN-Bus to the chime producer in order to give out the acoustic distance signal. Themeasuring range is between 30–120-cm (11.81–47.24-in). From a distance of 120-cm (47.24-in),the acoustic signal is active. The frequency of the beep sound increases with decreasingdistance. From a distance less than 30-cm (11.81-in),the sound becomes continuous.

Additional Warnings

The following warnings have an associated instrument cluster indicator or driver informationcenter message:

Turn Signal Indicators – The chime producer activates the audible warning as requestedby the BCM. The chime produces two different chimes, one when the turn signal turnsoff and another when the turn signal turns on.Vehicle Overspeed Message – The chime producer activates the audible warning as requestedby the BCM. The BCM sends a serial data message to the chime producer.Fuel Level Low Message – The chime producer activates the audible warning as requestedby the BCM. The BCM sends a serial data message to the chime producer.Oil Pressure Indicator – The chime producer activates the audible warning as requestedby the BCM. The BCM sends a serial data message to the chime producer.Park Assist Fault Clean Rear Bumper Message – The chime producer activates the audiblewarning as requested by the BCM. The BCM sends a serial data message to the chimeproducer.Tire Pressure Low Indicator – The chime producer activates the audible warning asrequested by the BCM. The BCM sends a serial data message to the chime producer.
