DTC Descriptor
DTC C0569
System Configuration
Circuit/System Description
The electronic brake control module receives serial data messages from other
modules. The electronic
brake control module must be configured with the Vehicle Identification Number (VIN),
configuration
data and vehicle options. If not properly configured after installation, the
electronic brake control
module may set a DTC.
The internal fault detection is handled inside the control module. No
external circuits are involved.
Conditions for Running the DTC
Ignition ON
Conditions for Setting the DTC
The electronic brake control module is not programmed.
Action Taken When the DTC Sets
- The traction/stability control indicator turns ON.
- The electronic brake control module disables the traction control, the
stability control and the hill
start assist for the duration of the ignition cycle.
Conditions for Clearing the DTC
- The DTC clears when the diagnostic runs and passes.
- The history DTC will clear after 40 consecutive fault-free ignition
cycles have occurred.
Diagnostic Aids
A newly replaced electronic brake control module can set one or more DTCs on
its initial ignition ON
cycle.

Steering Wheel Angle Signal
For symptom byte information refer to Symptom Byte List.
Circuit/System Description
The steering wheel angle sensor is integrated into the steering gear
assembly. The steering wheel angle
sensor identifies the position and direction of the steering wheel rotation.
The electronic brake control module receives high speed serial data inputs from
the steering angle sensor
identifying the position and direction of the steering wheel rotation. The
electronic brake control module
utilizes this signal to calculate the driver intended driving direction.
Conditions for Running the DTC
C0710 11
Drive the vehicle straight ahead with a constant speed no greater than 15
km/h (9.32 MPH) for a
distance at least 1.6 km (1 mi).
C0710 09
Vehicle ON or Vehicle in Service Mode.
C0710 0A
Vehicle stopped turn the steering wheel through its entire range of motion
from right to left.
C0710 0B
The EBCM detects the steering angle sensor is unprogrammed.
Conditions for Setting the DTC
C0710 09
The steering wheel angle sensor signal rate of change is to fast greater than
30º.
C0710 11
The steering wheel angle sensor signal is above the maximum specification.
C0710 0A
The steering wheel angle sensor signal has not changed.
C0710 0B
The EBCM detects the steering angle sensor is unprogrammed.
Action Taken When the DTC Sets
- The traction/stability control indicator turns ON.
- A Service StabiliTrak message may displayed on the driver information
center.
- A Service Brake Assist message may displayed on the driver information
center.
- A Service Power Steering Drive with Care message may displayed on the
driver information
center.
- The electronic brake control module disables the traction control and
the electronic stability
control for the duration of the ignition cycle.
Conditions for Clearing the DTC
- A current DTC clears when the diagnostic runs and passes.
- The history DTC will clear after 40 consecutive fault-free ignition
cycles have occurred.
Diagnostic Aids
- Check and adjust all tires to the stated cold air pressure as identified
on the tire placard.
- The car should not pull in either direction causing the steering wheel
to be off center while driving
in a straight line on a level surface.
- Confirm that all tires are of the proper size and matching brands. If a
mis-sized or non-matching
brand tire is present, inform the customer that in order for the vehicle
stability enhanced system to
function normally, tires need to be a uniform size and rolling diameter.
- Inspect the serial data circuits and connections at the power steering
control module and the
electronic brake control module. They should be free from sources of
electromagnetic interference
and the connections should be clean and tight.

Circuit/System Verification
1. Ignition ON.
2. With a scan tool check the Power Steering Control Module for any DTCs.
- If any DTCs are present in the Power Steering Control Module
- Refer to Diagnostic Trouble Code (DTC) List - Vehicle in Power
Steering Diagnostic
Information and Procedures.
- Go to next step: If there are no DTCs present in the Power Steering
Control Module
- With a scan tool check to see if DTCs U0126, U0130, or U0130 are set.
- With a scan tool check to see if DTCs C0035 - C0050 are set in the
Electronic Brake
Control Module
3. Perform the Steering Wheel Angle Sensor Centering procedure.
- If the Steering Angle Sensor Centering procedure corrected the DTC
Proceed to step 6
- Go to next step: If the Steering Angle Sensor Centering procedure did
not correct the
DTC
4. Replace the Steering Gear Assembly.
- If steering gear assembly replacement corrected the DTC
Proceed to step 6
- Go to next step: If steering gear assembly replacement did not
correct the DTC
5. Replace the Electronic Brake Control module.
6. All OK.
