Code C1668 Nissan Description

The 4 Wheel Active Steer (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.
