Codes 93fc and 93fd

[TheFixer]

So yes, I did some googling on this. Searched here as well. Can't find much.

I intermittently get this 93fc and 93fd code. It's for positive and negative terminals low voltage monitoring.

My battery is good, alternator is good, all grounds are good, no voltage drops under load, battery is coded correctly, etc.....

I can't figure out what is tripping it. So I just coded out the battery cable monitoring. Kills the lights but codes will still randomly pop when I check.

But yeah. I'm stumped.

Airbag module? IIRC you were rear ended a while ago.

Could be. I'll have to test it.
