Reboot with a good battery and instruct setup to restore the default settings. Setup has to autodetect the hard drive present, and than you will need to set the date.

If code 12 means the battery or computer has been disconnected how do you reconnect the computer?

Can you be more specific? Was your battery disconnected or did it lose it's charge? If you did not disconnect the computer, it would not need to be reconnected. If your battery was dead or disconnected, simply remove the positive battery cable for about 10 minutes and re-connect it. This should clear your code. Even if the code does not clear you should have no problems with the function of your car.

Why time does not stay where it is set in computer?

Some computers store the time with the help of a small internal battery known as the CMOS battery. The small battery will keep the clock of the computer running even if power is disconnected. If the computer are disconnected for to long however, the battery will run out and the time and date will be lost. If you are having problems with the time and date of your computer you should check that this battery is still working properly.


How do you reset the computer after taking loose the battery cable?

Usually, disconnecting the battery cable is what resets your car's computer(s) ... typically reverting to "default" settings and (sometimes) clearing any trouble codes. Generally, there's no need to do anything after you've reconnected the battery. Some cars have "learning" modes that adjust various settings based on your driving style, and it might take some time for the computer to re-learn everything. But there shouldn't be a big difference. A few cars have language display settings (German/English, for example) that "toggle" from one to the other each time the battery is disconnected. The owner's manual should explain how this works.

Do you have to take out the battery when changing a high voltage car fuse?

Don't have to take the battery out but it should be disconnected. Carefully disconnect the negative (usually black) battery cable from the battery. Be sure you do not let the connector end of that cable or the negative battery terminal touch anything! (I put a heavy-duty plastic baggie over the connecting end of the cable & secure it with a rubberband. No baggie ties!) If the free end of the cable, or the disconnected terminal, touches anything conductive it will short out whatever it touches & could cause hundreds (or thousands) of dollars of damage. It could even cause an explosion if there is hydrogen gas accumulated near the battery, serious injury, or even death. Once the negative battery terminal is disconnected, there should be no electricitity flowing anywhere, & it should be safe to change the fuse.


How do you get the car to drive when battery is reconnected?

If all you did was disconnect and reconnect the battery, it should function as normal. That is, assuming you disconnected the ground (negative) first when you took the battery out and reconnected the positive side first when replacing the battery. If you didn't, there's a possibility you toasted your ECM.
