No. Never take the battery cables off of any vehicle built after 2004, without the special tool installed in the OBD 2 port, you can cause programming loss in the processors, then you will have to go to a dealer and have it reflashed. If you mechanic replaced the clock spring he should have already done that as part of the job.

Plus you never take a battery terminal off of a running engine either, a voltage spike can fry every electronic device you have in the vehicle. A customer of mine learned that the hard way.

No, no, no. Do not do anything. Bring the vehicle to a qualified mechanic for repair. Disconnecting the battery could cause even more problems.

I want to thank everyone who responded I will not get under the hood except to check the oil and my other fluids.


Good idea, if your not dead certain of what you are doing don't chance it, especially on a late model, just too much to really mess up.

You cannot "reset" a clock spring. A clock spring is simply an electrical connection at the steering wheel, not an electronic device.

It's not about resetting the clock spring, per se, but the attached steering angle sensor whose output is needed to operate the ABS and traction controls. It's a complicated resetting procedure requiring the software to read and reset the system, but not restricted only to Subie stores. Shop around for someone with the software.
