OK so I was changing changing my h I d headlights and the passenger side would not turn on even tested the bulbs by switching. So then I checked the fuses, and I noticed that the used labeled HID headlight that the prongs were not in the fuse box, so I thought that maybe the prongs had somehow come out. And I disconnected the battery, completely pulled the fuse box out to try to see if I could see underneath the panel, I could not actually get to it. Or I did not feel comfortable enough. So I connected, everything makes sure everything was receded, and connected properly. I then connected the battery. Try to check the lights again with one of our crank. It up The car would not crank up. It would just click once, and that was it now. Also noticing that. That there is a security light on my dashboard that will not go away even when I put the key in the door and unlock it. And then put the key in the condition and turn it to the run.
I got a obd two scanner, and I am reading U0100 error and a pid 01&41 code the battery seems to either be bad or is draining faster than normal but I took it and had it tested and it said good so I'm at a loss and hoping o won't have to buy a whole new ecu
