C1440 2017 Toyota RAV4 Code - Steering Angle Sensor Unusual Bank Angle Detected
Quick Answer
If the Skid Control ECU (Brake Actuator Assembly) determines that the vehicle is being driven at a steep bank angle, the Skid Control ECU (Brake Actuator Assembly) stores Diagnostic Trouble Code (DTC) C1440 while VSC operation is temporarily disabled.
