Circuit/System Description
The steering angle sensor shares a 12-volt ignition
supply voltage with the electronic brake control module
(EBCM) and the yaw-rate/lateral sensor. The EBCM
applies a ground to the steering angle sensor low
reference circuit, which is shared with the yaw-rate/
lateral sensor. If equipped, this vehicle received the
steering wheel position signal from the power steering
control module (PSCM) over GMLAN.
The steering angle sensor provides a GMLAN signal
output to the EBCM that represents the steering wheel
degree of rotation. The EBCM utilizes this signal to
calculate the driver intended driving direction.
Conditions for Running the DTC
• The ignition is ON.
• 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 and
the DTC is cleared with a scan tool.
• The EBCM automatically clears the history DTC when
a current DTC is not detected in 100 consecutive drive
cycles.
Diagnostic Aids
• If DTC C0292 is set, diagnose that DTC first.
• If the steering wheel position sensor is disconnected,
DTCs will set and the EBCM will not provide 12-volt
reference.
• A poor ground connection for the EBCM may cause
this DTC to set.
