I recently changed my starter and had the battery disconnected for a few days waiting for the part to arrive. After installing the starter I took the van to the store and that is when I noticed that the VSA, ABS, and Brake light came on. The van drove without any issues at all speeds. I searched online to see if anyone had any ideas or experienced this problem. I came across something that mentioned that if you have the battery out for an extended period of time that those lights may come on. So I proceeded to try and reset the lights but had no success. I went to a mechanic to see if they could find out what the issue was. He connected the computer to the van and tried to reset the code, but the computer showed that it couldn't communicate with the ABS/VSA system. Any ideas on what it could be?
