Code C1445 Description

The C1445 code indicates that the vehicle has been driven with the Steering Angle Sensor not initialized. The Steering Angle Sensor is a crucial component of the vehicle's stability control system, as it provides information on the steering wheel angle and rate of turn. When the sensor is not properly initialized, it can lead to inaccurate data being sent to the vehicle's electronic control unit (ECU), resulting in potential issues with the vehicle's stability control, traction control, and anti-lock braking systems.
