2004 G35 coupe problems
Hi everyone I have a 04 coupe that I’ve been having some problems with. It started with my ebreak and battery light coming on very dim, tested battery and alternator and everything tested fine. Replaced battery terminals and nothing changed. Lights still on (very dim). Then my abs light would start flickering on and off and I could hear the pump clicking. Now the abs light is always on as well as my VDC off (they don’t work now) I’ve tried looking this up but can only find posts where the ABS, VDC AND SLIP lights are on, but my slip light is not on. The vehicle now Misfires all the time, engine light is on but no codes about the misfire. What could this be? I’m totally stumped. Here are the codes I got when I scanned it
P0500, P1574, P1212 and U1001.

How did you test the battery and how old is it?
Have you consulted the FSM?

You don't test a battery with a digital multimeter, you test the electrolyte with a hydrometer as posted above and you also test with a "load bank" that most parts houses have to test batteries.
A load bank basically makes the battery power a large heating element and a fan to simulate a 100amp current draw while it simultaneously measures for voltage drop. If it drops below spec during the load test it's garbage.
Using a digital multimeter to measure voltage without any kind of load on the system doesn't tell you much really.

During three repeated tests of my five year old battery over the course of a month last October produced these results on one battery cell.
I had the dealer replace my battery during a routine oil change and when it was two below zero here in NJ last Saturday my vehicle started right up.
