Malibu V6-191 3.1L VIN M SFI (1997)
ABS Light: Description and Operation
Circuit Description
When the EBCM needs to illuminate the ABS warning indicator or BRAKE warning indicators, it will transmit a signal (via serial data link) to the
electronic Instrument Cluster which will illuminate the indicator. The amber ABS warning indicator 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 warning indicator 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 Instrument
Cluster will illuminate the ABS warning indicator. The red BRAKE warning indicator has three functions. It will illuminate whenever the park brake is
set or when the brake fluid level within the master cylinder reservoir drops below a safe level. As a bulb check procedure, the EBCM will command the
BRAKE warning indicator 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 Instrument Cluster will illuminate the red BRAKE warning indicator.
