    C1732

    C1733

    C1734

    		 Absorber control actuator circuit Interrupts damping force control after moving to the 9th step (except when the actuator is malfunctioning). Returns to normal condition.
    C1781 Absorber control ECU Interrupts damping force control after moving to the 9th step. Returns to normal condition.
    C1782 Power source voltage Interrupts damping force control. Returns to normal condition.
    C1783 Vehicle speed sensor circuit

    • When there is a problem with the front right wheel speed sensor, control is interrupted after moving to the 9th step.

    • When there is a problem with the speed sensor of a wheel other than the front right wheel, control is continued.

    		 Returns to normal condition.
    C1784 Steering sensor Roll posture control is interrupted. Returns to normal condition.

    U0130 (*1)

    		 CAN communication system Roll posture control is interrupted. Returns to normal condition.
    U1103 (*2) CAN communication system Interrupts damping force control after moving to the 9th step. (*3) Returns to normal condition.
    Operates as if the vehicle is not equipped with a stop and start system. (*4)

    *1: w/ VGRS System

    *2: w/ Stop and start system

    *3: The absorber control ECU has not determined if the vehicle is equipped with a stop and start system.

    *4: The absorber control ECU has determined that the vehicle is not equipped with a stop and start system but receives information indicating that the vehicle is equipped with a stop and start system.
