Controller Anti-Lock Brake (Cab)
Fault codes are kept in a NonVolatile memory until either erased by the technician using the DRB II or erased automatically after 50 ignition cycles (key ON-OFF cycles). The only fault that will not be erased after 50 (KEY CYCLES) is the (CAB) fault, see CAB FAULT. More than one fault can be stored at a time. The number of key cycles since the most recent fault was stored is also displayed. Most functions of the (CAB) and (ABS) system can be accessed by the technician for testing and diagnostic purposes by using the DRB II.
