Brake Warning

The chime producer activates the brake audible warning as requested by the instrument panel cluster (IPC). The IPC sends a serial data message to the chime producer indicating the chime frequency and duration. 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 IPC receives a serial data message from the engine control module (ECM) indicating the vehicle speed.
• The IPC determines that the park brake is engaged.
• The brake fluid is low.
• The Traction Control System (TCS) and the Vehicle Stability Enhancement System (VSES) have failed.
