when one or more of the following occurs.
• | The IPC detects that the park brake is engaged. |
• | The electronic brake control module (EBCM) detects a low brake
fluid condition. The IPC receives a class 2 message from the EBCM
requesting illumination. |

proportioning (DRP). The IPC receives a class 2 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 approximately 3 seconds
before turning OFF. |
• | The IPC detects a loss of class 2 communications with the
EBCM. |
