Sorry, if this is in here already guys cant find. Was doing maintenance in my trunk area noticed I had dirty terminal on the negative side of my battery. Disconnected it and cleaned it. Put it back on in then car the car was completely dead . After many back-and-forth having jumped it on the fuse box, started it and back-and-forth overnight charging it. The 12 V has been low tested it works fine, even at 14 V. The car does nothing until jumped then behaves perfectly like normal. During this I did get a check hybrid system code but everything else now is normal and that code has stopped displaying. I am a little myth. I've checked a few fuses not all of them. looking for some insight can't be off the road. I'm an Uber driver in need this money badly. Shops can't get me in for three days nor can I afford it. help! tks
PS Throwing Codes: C1241 -to low or too high positive terminal voltage, C1311 Open Circuit in main relay 1, C1465 - Left front speed sensor
Test your voltage first thing in the morning, car off, with a multimeter. First directly at the battery posts, then at the under-hood jump point. Just curious: are you on original motor, and/or head gasket?
Yes check the car first thing in the morning before anybody's done anything at the terminals in the back of the car forget the jump poured up front let's not play with that that's really weak You get a big enough clamp on that thing and you'll break it or something will happen and then we have another mess I have a remote charging cable on my battery in the back in a little hole in the tray and it just lays there on top of that tray so when I want to plug up a charger or test the battery I don't have to move any plastics but you will no matter It sounds to me like your batteries not stable it's able to hold more voltage maybe than the car would like it to have I don't know being that it's looking at the negative being too low which should be very low or negative or the positive being too high which I don't know what that threshold would be because the car charges from the inverter at like 14 3 14 5 somewhere in there and that's not too high and I can't imagine your battery being able to hold much more voltage than that 14.5 or is it going to come from?. The sensor code for the wheel sensor and all that is probably happening because for some reason something is wrong in the 12 volt supply and the computer's know it and it's making them go wonky sitting weird codes of course you'll go look at that wheel sensor and make sure it's sitting there and it's intact and it's not ripped I had a ripped one 3 weeks ago so you want to verify that the wheel sensors are all there in place not spliced not cut so on and so forth. And then I guess report back
