SYSTEM BRC-33 < SYSTEM DESCRIPTION > [WITH VDC] C D E G H I J K L M A B BRC N O P ABS FUNCTION : System Description INFOID:0000000006222574 • By preventing wheel lock through brake force (brake fluid pressure) control that is electronically controlled by detecting wheel speed during braking, stability during emergency braking is improved so that obstacles can • During braking, control units calculates wheel speed and pseudo-vehicle speed, and transmits pressure increase, hold or decrease signals to actuator portion according to wheel slip status. • The following effects are obtained by preventing wheel lock during braking. - Vehicle tail slip is prevented during braking when driving straight. ing driving on a corner. - Obstacles may be easily bypassed by steering operation during braking. • Slight vibrations are felt on the brake pedal and the operation noises occur, when ABS function operates. This is not a malfunc- • CONSULT-III can be used to diagnose the system diagnosis. function, the control is suspended for VDC function, TCS function, . NOTE: device that helps reckless driving. • To stop vehicle efficiently, ABS does not operate and ordinary brake operates at low speed [approx. 5 to 10 km/h (3.1 to 6.2 • Self-diagnosis is performed immediately after when engine starts and when vehicle initially is driven [by vehi- cle speed approx. 15 km/h (9.3 MPH)]. Motor sounds are generated during self-diagnosis. In addition, brake SYSTEM DIAGRAM NOTE: JPFIC0140GB |
