Outline of functions
Send alternating current signals at frequencies which are
proportional to the rotation speeds of each wheel to the
ABS-ECU
Sends data on vehicle's rate of lateral acceleration to the
ABS-ECU
Sends data on vehicle's rate of longitudinal acceleration to the
ABS-ECU
Sends data on steering wheel angle to the ABS-ECU
Informs the ABS-ECU when steering wheel is in straight-ahead
position
Sends a signal to the ABS-ECU to inform whether the
brake pedal is depressed or not
Sends a signal to the ABS-ECU to inform whether the
parking brake lever is pulled or not
Drives the solenoid valves according to signals from the
ABS-ECU in order to control the brake hydraulic pressure
for each wheel
Illuminates in response to signals from the ABS-ECU
when a problem happens in the system
Outputs the diagnosis codes and allows communication
with the MUT-II
Controls actuators (described above) based on the signals
coming from each sensor
Controls the self-diagnosis and fail-safe functions
Controls the diagnosis function (MUT-II compatible)
