Check charging system light came on?

Hello MAMABIRD,

The first thing we need to do is check for power through fuse #9 in the fuse panel behind the right kick panel and fusible link A and B in the main fuse panel under the hood.

This guide can help you test the fuses:

I have included the fuse locations as well as the alternator wiring diagrams so you can see how the system works. Please let us know what you find. The fusible links are in the main wiring harness near the alternator. If test the blk/org wire at the alternator it should have power that way you know the fusible links are okay. Also, we should run the codes to see what comes up.

Please let us know what happens. Check out the images (below).

As you can see by the wiring diagram the system is pretty straightforward and it sounds like the voltage monitoring portion of the PCM is not working. I would get a rebuilt unit by searching google or eBay and install it. Here is the location and direction on how to do the job. The PCM doesn't need programming so it will be an easy fix. Also, when you have the electrical connector off of the PCM check the pins for rust or corrosion. Please get back to us and check the images below.
