P16-Instrument Cluster
The instrument cluster turns the brake warning indicator ON when the following occurs:
The instrument cluster performs the bulb check. The brake warning indicator illuminatesfor 5-s.When the Electronic Brake Control Module (EBCM) detects low brake fluid level it setsDTC-C0267 and sends a serial data message to the instrument cluster, which will illuminatethe red brake indicator.The Body Control Module (BCM) detects that the parking brake is engaged. The instrumentcluster receives a serial data message from the BCM requesting illumination.Driver Information Center MessagesWhen the Electronic Brake Control Module (EBCM) detects low brake fluid level it setsDTC-C0267 and sends a serial data message to the Driver Information Center , whichwill display Brake Fluid Low message.
