Brake Warning System Description and Operation (Without
Antilock Brake System)
Brake Warning Indicator
The instrument cluster turns the brake warning indicator ON when
the following occurs:
• |
The instrument cluster
performs the bulb check. The brake warning indicator illuminates
for 5 s. |
• |
When the body control module
(BCM) detects a too low brake fluid level, it sends a serial data
message to the instrument cluster, requesting illumination.
|
• |
The BCM detects that the
parking brake is engaged. The instrument cluster receives a serial
data message from the BCM requesting illumination. |
