Brake Warning

The chime producer activates the brake audible warning as requested by multiple control modules. The BCM, electronic brake control module or the parking brake control module sends a serial data message to the chime producer indicating the chime as a multiple gong. The brake warning sounds and the BRAKE indicator illuminates when the following occurs:

• The ignition is ON.
• The vehicle speed is greater than 8 km/h (4.9 mph). The instrument cluster receives a serial data message from the Battery Energy Control Module indicating the vehicle speed.
• The BCM determines that the parking brake is engaged and the signal circuit is low.
• The brake fluid is low.
