Basic Control

PHASE 0-PHASE 1: When ABS ECU detects the wheel locking, ABS ECU changes PHASE 0 to PHASE 1.

PHASE 1-PHASE 2: If wheel cylinder liquid pressure is decreased, ABS ECU changes PHASE 1 to PHASE 2.

PHASE 2-PHASE 3: If it is judged that there is no lock phenomenon in wheel, ABS ECU changes PHASE 2 to PHASE 3.

PHASE 2-PHASE 4: If wheel cylinder liquid pressure is cascading on the deceleration section, ABS ECU changes PHASE 2 to PHASE 4.

PHASE 2-PHASE 5: If wheel cylinder liquid pressure is cascading on the acceleration section, ABS ECU changes PHASE 2 to PHASE 5.
