Try putting in bosch spark plugs with the 3 electrodes ,might help .As for the code reading well i wouldnt trust that because as its a new car then the chances are its encrypted software so the code you have will not be right.If the plugs do not cure it then its dealer only and i wouldnt be surprised if it didnt end up with a new ECU unit

That would be your computer system trying to tell you that there is a malfunction in your traction and stability control system. You will have to access the computer data in order to find out the nature of the failure and to diagnose the problem.
SOURCE: I have a 2007 chev
On 2007
Equinox I was told it is a problem with a bad connection sending the
wrong message to the computer. Contact your Chevy dealer and ask about be a recall issue.
That could be one of a few things, and I really can't say that it is safe to drive, (not being able to drive it myself) however, there has been a service bulletin on a reprogramming of the EBCM and PSCM modules before any parts are replaced.
You will of course want to check the fuses, just to be sure. Here is what the bulletin states.
Brakes/Steering - DTC's C0252/C0460/C056E/C0460/C0545
Notes
Bulletin No.: 07-02-32-009
Date: September 28, 2007
INFORMATION
Subject: Information on Electronic Brake Control Module Set DTCs C0252/C0460 and Power Steering Control Module Set DTCs C056E/C0460/C0545
Models:
2007-2008 Chevrolet Equinox
2007-2008 Pontiac Torrent
If any of the following DTCs are found (current or history), the following procedure should be performed before any components are replaced.
C0252 4A
C0460 71
C0460 4B
C0460 5A
C0460 42
C056E 4B (history only)
C0545 00 (history only)
Make sure the Tech 2(R) is updated with version 27.010 or later.
Reprogram the electronic brake control module (EBCM) software with the latest version.
Reprogram the power steering control module (PSCM) software with the latest version.
After the software has been updated, perform the following checks using the Tech 2(R):
Verify under the diagnostic menu that the STEERING WHEEL ANGLE reads zero when the wheels are pointed straight ahead.
Verify under the diagnostic menu that the STEERING WHEEL ANGLE SENSOR CALIBRATION STATUS reads calibrated.
Verify under the diagnostic menu that the STEERING WHEEL ANGLE VALIDITY reads valid.
If any of the above checks are incorrect, perform the following procedure using the Tech 2(R):
Clear all the codes.
Perform the "Steering Pos./Torque Sensor Calibration" in the power steering control module. During the calibration procedure steering assist will not function. Raising the vehicle off the ground will reduce the steering loads and make it easier to perform the procedure.
Perform the "Steering Pos. Sensor Calibration" in the electronic brake control module.
Verify that there are no DTCs.
Test drive the vehicle.
The "SERVICE STABILITRAK" message may stay on after the codes have been cleared. It may be necessary to drive the vehicle before the message turns off. This allows the EBCM to verify that no malfunctions exist before turning off the message.
Hope helps.
