Electronic Brake Control Module: Description and Operation
The Bendix Anti-lock Brake System (ABS) control module (CAB) has enhanced diagnostic capability through the use of microprocessor technology. Several advantages have been designed into the system utilizing this technology. First, trouble codes are retained in non-volatile memory until either erased by the technician using the Diagnostic Readout Box (DRB), or erased automatically by the CAB after 3500 miles. Second, more than one trouble code can be stored at a time. Third, using the DRB, most functions of the CAB and the ABS system can be accessed by the technician for testing and diagnostic purposes.
