ABS ECU<br />

The ABS ECU is integrated with the hydraulic unit to achieve a compact and lightweight design.<br />

As shown in the block following diagram, the ABS ECU receives wheel sensor signals from the front<br />

and rear wheels and also receives signals from other monitor circuits.<br />

The necessary actions are confirmed using the monitor circuit and control signals are transmitted to<br />

the hydraulic unit assembly.<br />

ABS control operation<br />

The ABS control operation performed in the ABS ECU is divided into the following two parts.<br />

Hydraulic control<br />

Self-diagnosis<br />

When a malfunction is detected in the ABS, a fault code is stored in the memory of the ABS ECU for<br />

easy problem identification and troubleshooting.<br />
