Fail-Safe Chart

  1. FAIL SAFE OPERATION 

    If there is a problem with sensor signals or actuator systems, the skid control ECU prohibits power supply to the brake actuator and prohibits ABS control.

    The ABS control will be prohibited, but EBD control continues as much as possible. If EBD control is impossible, the brake warning light comes on to warn the driver.

    ABS AND EBD SYSTEM SYMPTOM

    Malfunction Symptom
    ABS system ABS control prohibited
    EBD system ABS & EBD control prohibited

    HINT:

    If the ABS system encounters a malfunction, the brake system will operate normally without ABS control.
