Hi,
The first thing you would need to do is find out what is causing the light to come on. In order to do that, you need to connect the van to a scan tool or code reader to find out what Diagnostic Test Codes (DTC) are stored in the computer. These will tell you what happened to cause the light to come on in the first place.
Once you have the code or codes, then you will have an idea of what happened and what steps are needed to repair the problem and turn the light off. Most scan tools and code readers can turn the light off, but if the problem is not repaired, then it is very likely that the light will just come back on in a short period of time.
To find the meaning of the codes, you can search the internet for the exact code to find out what your next step would be. I have provided a link to a site that lists many of the codes for this van.
Good Luck, Greg
