OPERATION

NOTE: If the ABM nodule is replaced it must be initialized using the scan tool.

The ABM voltage is supplied by the ignition switch in the RUN position. The ABM contains dual microprocessors. A logic block in each
microprocessor receives identical sensor signals. These signals are processed and compared simultaneously. The ABM contains a self check program
that illuminates the ABS warning light when a system fault is detected. Faults are stored in a diagnostic program memory and are accessible with the scan
tool. ABS faults remain in memory until cleared, or until after the vehicle is started approximately 50 times. Stored faults are not  erased if the battery is
disconnected.
