ABS CONTROL UNIT CALCULATING PROCESS
The ABS controls and its calculations, in addition to the self-diagnosing and the fail-safe processes, occur
during the ABS control unit calculating process. In addition, if a malfunction is detected by the self-diagnosis
function, the brake stops being controlled by the ABS and a diagnostic trouble code is stored.
