The instrument panel cluster (IPC) illuminates the ABS indicator by supplying ground to the lamp. The electronic brake control module (EBCM) sends class 2 serial data messages to the IPC in order to command the indicator ON or OFF.
Replace the Instrument Panel Cluster if the ABS indicator intermittently fails to operate during the bulb check.
