C1231Steering angle sensor circuit fault

• Toyota/Lexus code · ABS / stability control
• Lights a warning lamp

How the car detects it

The steering angle signal the stability control needs is missing or faulty. The sensor sits in the steering column and talks to the skid control unit over CAN. On some 2009-2011 Camry with Bosch ABS, Toyota updated the ABS unit logic for this code. While this fault is stored, the skid control unit may switch off VSC (stability control) and traction control, and sometimes ABS; normal braking still works. Drive gently and have it checked.
