The DTCs above are stored during the self diagnosis of the seat belt control ECU.

This DTC is stored when the vehicle is driven at a vehicle speed of 5 km/h (3 mph) or more and a malfunction occurs in the yaw rate sensor.

This circuit consists of the yaw rate sensor and seat belt control ECU.

This DTC is stored when the beam axis of the millimeter wave radar sensor is not aligned with the direction the vehicle is traveling. If the beam axis adjustment is not performed after installing a new millimeter wave radar sensor, the pre-crash safety system DTC B2056 is output, and when the vehicle speed is 40 km/h (25 mph) or more, the dynamic radar cruise control system DTC P1572 is output.

The seat belt control ECU receives information from the master cylinder solenoid (skid control ECU) via the CAN communication line and tightens the seat belt by operating the motor in the front seat outer belt assembly RH or LH.

This DTC is stored when there is a malfunction in the communication from the millimeter wave radar sensor. This DTC is also stored when the vehicle information sent from the millimeter wave radar sensor is abnormal.

In these cases, perform initialization so that the millimeter wave radar sensor recognizes the vehicle information.

The seat belt control ECU receives information from the master cylinder solenoid (skid control ECU) via the CAN communication line and tightens the seat belt by operating the motor in the front seat outer belt assembly RH or LH.

If the seat belt control ECU judges that there is a malfunction in its internal circuit as a result of self-diagnosis, or if the power source voltage (+B) is not input to the seat belt control ECU, this DTC will be stored.

The seat belt control ECU receives information from the master cylinder solenoid (skid control ECU) via the CAN communication line and tightens the seat belt by operating the motor in the front seat outer belt assembly RH or LH.
