2009 Z06. Only mod is headers. Took the car in for clutch repair which they said it was a known issue and was covered and called me when it was fixed. Went to pick it up. Now the check engine light has been on since headers were done. So I knew that was on but get in the car and now the traction control light is on and showing a message. Also noticed that the battery must have been disconnected because all stations were set back to factory on the radio and backup camera would not work. Friend fixed that. Took the car back to dealership they first said it needed a new computer so they fixed that and still have the issue. They are basically saying, "we are not sure that light wasn't on prior when you brought it in". That light/message has never been on. They assured me that they "did nothing that involved the battery and did nothing that would set off the message".

So now they are telling me that its my "not factory" air intake and are telling me that I have that off and make it 'factory' again and then they can clear the message but it will probably come back on because by my mods are making it 'run lean' and causing this error. Again NEVER had this before!! ever!

Any ideas? Im picking the car up tomorrow and just taking it somewhere else I guess. I only have 9000 miles on this car and never had one issue until the clutch went out.

Any ideas?

 

Circuit/System Description
The electronic brake control module (EBCM) disables the traction control when other electronic control modules set DTCs for components that affect the operation of the traction control system (TCS).

Conditions for Running the DTC
• The ignition is ON.

• Ignition voltage is greater than 8 volts.

Conditions for Setting the DTC
The engine control module (ECM) or body control module (BCM) diagnoses a condition preventing the engine control portion of the traction control function and sends a high speed GMLAN serial data message to the EBCM indicating that torque reduction is not allowed. The ECM or BCM will typically set a DTC and the EBCM will set DTC C0561.

Action Taken When the DTC Sets
• The EBCM disables the TCS while the DTC is current.

• The traction control off indicator turns ON.

• The driver information center (DIC) displays the TRACTION SYSTEM OFF message.

• The antilock brake system (ABS) remains functional.

Conditions for Clearing the DTC
• The condition for setting 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.

Diagnostic Aids
This DTC is for information only. As an aid to the technician, this DTC indicates that there are no problems in the ABS/TCS.
