C0460 = Steering position signal.
The electronic brake control module (EBCM) supplies ignition voltage to the steering angle sensor and the yaw-rate/lateral sensor. The EBCM receives serial data messages from both the steering angle sensor and the yaw rate/lat sensor.
The steering angle sensor serial data message to the EBCM represents the steering wheel degree of rotation. The EBCM utilizes this signal to calculate the driver intended driving direction.
Conditions for Running the DTC
Ignition voltage is greater than 9.5 volts.
Conditions for Setting the DTC
" Steering angle sensor is reporting an internal electronic failure.
" Steering angle sensor has not been initialized.
" Steering angle sensor offset is greater than 15 degrees.
Action Taken When the DTC Sets
" Vehicle stability enhancement system (VSES) are disabled.
" The VSES indicator turns ON
" The driver indicator turns ON
Conditions for Clearing the DTC
" The condition for 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.
" If the steering wheel position sensor is disconnected, DTCs will set and the EBCM will not provide voltage to the sensor.
" A poor ground connection for the EBCM may cause this DTC to set.
" Improperly mounted or loose steering angle sensor.
