Car will not start

[gregory20]

Car has been sitting for 4 month and the battery died. Replaced the battery, but now the car will not start. Here are the code it's throwing. Need help figuring this out

AOC1 - this is what is keeping you from starting

It means that 'Terminal 50' which provides the power to the starter solenoid, is not activated. Your problem is most likely a fault in the CAS module (which is the source of Terminal 50), although there are some other possibilities, for example an internal short in the solenoid or a short in the wire from the CAS to the solenoid.

Latter two are easily checked and if OK, leave a CAS fault as the most likely culprit.

Just another thought to follow on from dpaul post above: There is a recall on the fuse box ground and the battery cable due to corrosion (I think). Perhaps it's coincidence, but IF some terminals (50) of the fuse box are dead then this might be worth checking..

Terminal 50 is not directly related to the fuse box i.e. there is no Terminal 50 fuse and there is no Terminal 50 supply to the fuse box. I doubt that this is related to the JBE-power cable recall but who knows.

But DrFerry has a point- could be one of the CAS fuses, F55 (5A),F36 (40A). One should always check fuses.
The two other faults would not interfere with starting or running the engine. They are communication faults but since the alternator and DSC utilize different busses, I suspect those are related to the low voltage condition and would disappear if cleared.

Ok thanks for all the feedback. I will check the fuses tomorrow. Whats the possibility its the starter, and can i push start it with a bad starter

IMO zero chance it's the starter itself but some chance it's the solenoid, in which case the simplest/best thing to do is replace starter/solenoid as a unit.

You can push start a manual trans. Have no idea if that's possible with a DCT

Possible rodent damage? I almost lost an engine wiring harness on my grocery getter due to a rat infestation one winter. They can cause all sorts of weird shorts.

Give the fuse box a good shake if it's related to the recall. It happened to me, the car was completely unresponsive; shook the fuse box and it came right to life. Takes like five seconds, couldn't hurt to try, lol.
