1999 Dodge Caravan 6 cyl Front Wheel Drive Automatic 78xxx miles

hi after about a year of my moms van sitting in her garage. She decided to sell her van. So obviously the battery was dead. I replace it with a brand new battery. Now when I open the door, the dash lights, and parking lights start flashing like the factory alarm is going off.

so I start the car, drive around the block and still the alarm keeps going off. What would cause this. Do I have to "reset" something because I put a new battery in?

thanks for any help!

Unlock one of the front doors with the key.

The remote should work too. If it does, and the doors don't, look for broken wires between the door hinges, or the switches are broken or disconnected.

Actually, if you're driving the van, it isn't in theft mode. The only thing the dash lights and running lights have in common is the Body Computer. That computer adds a lot of complexity and unreliiability to otherwise simple circuits. Unfortunately there is no easy way to test it other than to replace it. It sits up high against the firewall, inside the passenger compartment, ahead of the brake pedal. It unplugs when you pull it down, that's why troubleshooting is next to impossible.

The dealership mechanics, and some independent shops with hand-held computers that can access the Body Computer can use it to activate various functions and to read the state of the sensors and switches feeding the computer That will give some clues as to whether the computer is acting up or if it is responding to something.
