So I have a 2002 Chrysler 300m 3.5l for the last 2 weeks when I release the brake I feel a popping in the driver side area same when going over a bump now I wasnt observant on the braking when going over the bumps but very possible. Anyways last night I used a over the counter obd2 meter and ran a check on the abs system and it came back low circuit voltage then I decided to run a test on my battery it did come back with "Warning" as in I need to replace the battery. There are no abs lights on or anything of the sort but it does bother me a bit. My check engine light is on but for a p0056 code in which case both my downstream o2 sensors need to be replaced still. Wondering if replacing the battery would solve my issue or if its something more serious any and all help is appreciated. Thx.
