nah its all good. i changed the battery just a few months ago with an OEM one so i guess its probably something to do with the sensors
I have been having some ABS related issues that trip a TCS off light sometimes, as well as throw the ABS Inop light, but never at the same time. Anyway, my issue is a bad/going bad wheels speed sensor. If you know anyone with a more in depth scan tool or take it to the dealer they can pull your ABS codes and you can see the problem.
def check the sensors, and about a foot down the wire from the sensor going to the body (if that makes sense) there is another extension connector around the lower a-arms in front, and around lca's in rear along the same wires. for me it was this connection not the speed sensor that was giving it a faulty signal. also check your PWR ACCRY fuse on the panel inside the drivers door, cant remember why but this helped also; or other fuses in same spot or under hood...
I have this problem and had it scanned with a snap-on scanner. It is the abs module itself going out. The 3 lights are off every morning when I first start the car and I usually drive for 5 miles or so and all 3 lights come on at once. When this happens the tcs sys is not able to be re acvtivated till the car sits overnight and all the lights go back out. I have since aquired hp tuners myself but havent tried to read codes with it yet. Hope this helps.
