BRAKE WARNING LAMP, ABS WARNING LAMP, ASTC INDICATOR LAMP, ASTC OFF INDICATOR LAMP
Brake warning lamp
- For approximately 3 seconds after the ignition key is turned ON (Initial check for
the brake warning lamp.)
- When malfunction occurs in EBD (Stays ON until the ignition switch is turned OFF.)
- When the G & yaw rate sensor or steering wheel sensor has not learned the
neutral point (Flashes at a rate of 1 Hz.)
- For approximately 3 seconds after the ignition key is turned ON (Initial check for
the ABS warning lamp.)
- When illumination is required by operating the actuator forcibly
- When malfunction occurs in ABS (Stays ON until the ignition switch is turned OFF.)
- When the supply voltage for ASTC-ECU is abnormally reduced (Turns OFF when the normal supply
voltage is resumed.)
- When the G & yaw rate sensor or steering wheel sensor has not learned the
neutral point (Flashes at a rate of 1 Hz.)
- For approximately 3 seconds after the ignition key is turned ON (Initial check for
the ASTC indicator lamp)
- When illumination is required by operating the actuator forcibly
- When the G & yaw rate sensor or steering wheel sensor has not learned the
neutral point (Flashes at a rate of 1 Hz.)
- During the ATC control (Flashes at a rate of 4 Hz.)
- During the ASC control (Flashes at a rate of 4 Hz.)
- For approximately 3 seconds after the ignition key is turned ON (Initial check for
the ASTC OFF indicator lamp)
- When illumination is required by operating the actuator forcibly
- When the G & yaw rate sensor or steering wheel sensor has not learned the
neutral point (Flashes at a rate of 1 Hz.)
- When malfunction occurs in ABS (Stays ON until the ignition switch is turned OFF.)
- When the ASC switch is operated and ASC is turned OFF
- The system is stopped to protect ASTC-ECU from heat (Flashes at a rate of 2 Hz.)
