ABS Light: Description and Operation

INDICATORS
The electronic brake control module (EBCM) continuously monitors itself and the other ABS components. If the EBCM detects a problem with the system, the amber ABS indicator will either flash or light continuously to alert the driver to the problem. The ABS indicator will flash if the problem does not immediately hamper ABS operation. However, a flashing ABS indicator signals the driver that repairs must be made to the system as soon as possible.
A solid ABS indicator indicates that the ABS system has detected a problem that affects the operation of the ABS. No antilock braking will be available. Normal, nonantilock brake performance will remain. In order to regain ABS braking ability, the ABS must be serviced.
The red BRAKE indicator will be illuminated when the system detects a low brake fluid level in the master cylinder, the parking brake switch is closed (parking brake engaged), or the ignition switch is ON and the engine is not running or under control of the EBCM. The EBCM will illuminate the BRAKE indicator when an ABS fault could interfere with base brake operation. When this type of fault is detected, the EBCM will store the appropriate diagnostic trouble code (DTC), store a DTC A086 (indicating that the EBCM has turned the BRAKE indicator on), and disable the ABS.
