ABS Light: Description and Operation
DESCRIPTION
When the EBCM needs to illuminate the ABS indicator or BRAKE warning lamps, it will transmit a signal (via serial data link) to the Electronic
Instrument Panel Cluster (IPC) and the IPC will illuminate the indicator lamp.
-
The amber ABS indicator lamp will be illuminated to alert the driver of a malfunction. This indicates that the malfunction affects operation of the
ABS. Normal (non-antilock) braking will remain. In order to regain ABS braking ability, the ABS must be serviced. As a bulb check procedure,
the EBCM will command the ABS indicator lamp ON for 3 seconds when the EBCM receives power (ignition in RUN or START positions). With
the ignition in the OFF/UNLOCK position (loss of serial data), the IPC will illuminate the ABS indicator lamp.
-
The red BRAKE warning lamp has two functions. It will illuminate whenever the park brake is set (direct input to the IPC) or when the brake fluid
level within the master cylinder reservoir drops below a safe level (commanded by the EBCM via serial data link). As a bulb check procedure, the
EBCM will command the BRAKE warning lamp ON when the EBCM receives power (ignition in RUN or START position). With the ignition in
the OFF/UNLOCK position (loss of EBCM serial data), the IPC will illuminate the BRAKE warning lamp.
