ABS/VSA/TCS lights on, but ABS works
Hi all, so my abs, vsa and tcs (triangle with exclamation mark) light all came on the other day as I was driving. Did not feel anything, car drives just fine. They have gone away and come back randomly. Anyway I pulled the codes yesterday when they were on and this is what I get:
- Internal power source failure
-ecm/pcm relation failure
-brake switch failure
-battery voltage failure
-abs pump motor failure
Nothing that I know of happened to the car that should have caused this. Also ABS works fine (tested it by braking hard and felt the pedal vibrate), brake lights all work as well. If anyone has any suggestions, they are greatly appreciated.

Fixed the issue. Cleared all codes but Traction control light would stay on and VSA would come on after driving for a few min. A couple other codes came back, one was "sensor logic failure". Cleared all codes (this must be done before vsa relearn) and did the VSA relearn procedure (Error Code 84 - VSA sensor neutral position memorization - Acura TSX Forum) and that fixed all my issues. Hope this can help someone in the future.
