lamp may continue illuminating. When a
diagnosis code, which is associated with
the wheel speed sensor, the G sensor,
the yaw rate sensor or the steering
wheel sensor, is set in the ASTC-ECU as
a historic fault, the ECU will allow the
warning/indicator lamp to
illuminate until the relevant fault is
cleared.
- *2: The brake warning
lamp does not turn "OFF" when the
parking brake is applied or the brake
fluid level is lowered.
