I have to be honest. I have only ever seen that one time. I'm adding my thoughts simply because I know you were working around the battery and that is where the problem was I dealt with.
I found that the PCM wiring harness was chafing against the battery tray. Since you were working around that area, check the harness to the PCM. Move it around and inspect it and see if moving the harness changes anything.
Let me know what you find.
