Buick Regal: DTC C0569

Diagnostic Instructions

• Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure.
• Review Strategy Based Diagnosis for an overview of the diagnostic approach.
• Diagnostic Procedure Instructions provides an overview of each diagnostic category.

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

1. With a scan tool check to see if DTCs U0126, U0130, or U0130 are set.
   • If DTCs U0126, U0130, or U0131 are set

     Refer to Diagnostic Trouble Code (DTC) List - Vehicle

   • Go to next step: If DTCs U0126, U0130, and U0130 are not set
2. With a scan tool check to see if DTCs C0035 - C0050 are set in the Electronic Brake Control Module
   • If DTCs C0035 - C0050 are set in the Electronic Brake Control Module

     Refer to Diagnostic Trouble Code (DTC) List - Vehicle

   • Go to next step: If DTCs C0035 - C0050 are not 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
