Conditions for Setting the DTC

Any of the following conditions may cause the DTC to set.

• The steering angle calculated by the EBCM does not correlate with the steering angle information which is being transmitted on the serial data line.
• When driven forward in a straight line, the centered steering angle differs by more than 30 degrees from the centered steering angle when the sensors are initialized.
• The EBCM detects an erratic signal from steering wheel position signal A or signal B.
• The BCM detects an invalid steering wheel position sensor signal, sets a DTC, and therefore, cannot transmit valid serial data information. The BCM sends a serial data message to the EBCM, which causes the DTC to set.
• The EBCM detects an open or shorted steering wheel position signal A or signal B, after having received a valid signal during the same ignition.
