BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS  ELECTRONICALLY CONTROLLED BRAKE SYSTEM(w/o VSC OFF Switch)  FAIL-SAFE CHART  

When the skid control ECU (brake actuator assembly) detects a solenoid valve malfunction or abnormal signal from a sensor, the brake actuator assembly cuts power and sends a signal indicating a malfunction of the electronically controlled brake system to the ECM.

HINT:

Based on signals sent from the skid control ECU (brake actuator assembly), the brake actuator assembly prevents the solenoids from operating, and the ECM no longer accepts fuel-cut request signals from electronically controlled brake system.

If a malfunction of ABS is detected, operation of the function is prohibited and the related warning lights illuminate.

The EBD function can still operate even if operation of the ABS function is prohibited. However, if the EBD function is also affected, operation of the EBD system will be prohibited and the brake warning light illuminates.

HINT:

When a component of the electronically controlled brake system is in fail-safe mode, operation is prohibited. However, if the system enters fail-safe mode while braking is being controlled, control is gradually suspended to prevent sudden changes in vehicle behavior.
