### Brake Warning Indicator

The instrument panel cluster (IPC) illuminates the brake warning indicator when one or more of the following occurs.

• | The body control module (BCM) detects that the park brake is engaged.

• | The BCM detects a low brake fluid condition. The IPC receives a serial data message from the BCM requesting illumination.

• | The electronic brake control module (EBCM) detects a malfunction and disables the antilock brake system (ABS). The IPC receives a serial data message from the EBCM requesting illumination.

• | The IPC performs the bulb check at the start of each ignition cycle. The brake warning indicator illuminates for briefly 3 seconds turning OFF.

• | The IPC detects a loss of communications with the EBCM.
