Will replacing a bad heater valve solve abs, trac control, and service emergency brake light issue

Hello, sounds like something happened when you replaced the battery, as that's the variable involved here. Sometimes electrical concerns can happen when you have low battery power or replace a battery. Sometimes you'll need a diagnostic tool to evaluate and clear each code to see if there's a real problem that remains. Finally, ensure all fuses are intact and good, as an arc when replacing the battery could have blown a fuse.
