The steering wheel position sensor supplies 2 analog inputs, Phase A and Phase B, to the electronic brake control module (EBCM). The 2 input signals are approximately 90 degrees out of phase. By interpreting the relationship between the 2 inputs, the EBCM can determine the position of the steering wheel and the direction of the steering wheel rotation.
| • | The ignition is ON. | 
| • | Ignition voltage is greater than 8 volts. | 
| • | The vehicle speed is less than 10 km/h (6.2 mph). |

| • | The multi function display (MFD) displays the Stability Ctrl Off message. | 
| • | The condition for setting the DTC is no longer present. | 
| • | The EBCM automatically clears the history DTC when a current DTC is not detected in 100 consecutive drive cycles. | 
| • | The DTC can be cleared using a scan tool. |
