DTC C1669: Incomplete Lock Release: Description
- Wiring connected to 4WAS front actuator is integrated with 4WAS front actuator.
- 4WAS front actuator rotates together with steering wheel.
- 4WAS front actuator mainly consists of five components. [4WAS front lock solenoid valve (lock structure), front wheel steering angle sensor, 4WAS front motor, gear shaft, and spiral cable]
- 4WAS front lock solenoid valve (lock structure) is controlled by the 4WAS front control unit, and locks/unlocks 4WAS front actuator.
- If a strong force (rotation direction) is applied to 4WAS front actuator, the locking mechanism (holder) absorbs the force and locks 4WAS front actuator.
- Front wheel steering angle sensor detects a turning angle of 4WAS front motor.
- 4WAS front motor controls number of revolutions by a command value from the 4WAS front control unit.
- Gear shaft is an output axis of 4WAS front motor. (Gear shaft = 4WAS front motor revolution + steering angle)
- Spiral cables mean the power line and signal lines of 4WAS front motor.
