Code Errors for 2004 Cadillac Deville
I’ve asked for help on this in the past but wasn’t able to get any help. I have this strange light/electrical problem. My interior lights won’t turn on by themselves when it’s dark. I can only manually turn on the map lights with each button. They don’t turn on when I manually open the doors or when I unlock my doors with the key fob and they don’t turn on when I move the interior dimming **** all the way over. That should turn the lights on. Also, the lights on the bottom of the door (puddle lights) don’t ever turn on. I decided to run the on board diagnostics and I get the following errors. Not quite sure if it will solve my problems but they are valid codes so I want to see what they mean.
Here are the codes that I’m getting. Theses seem to be Network Codes from what I’ve read.
U1000 – Class 2 Communication Malfunction
U1016 – Loss Of Class 2 Communication with VCM or Loss Of Communication with PCM
U1065 – Loss Of communications with IPM
U1176 – Loss Of RFA communications
My confusion is that while running the diagnostics, it comes up with the following along with a bunch NO CODE. For you guys that have run this, you know that it checks each "system" and either displays NO CODE or it will display an error code. I didn’t write them all down but these stuck out to me so I wrote them down.
NO RFA CODE
NO IPM CODE
What I don’t understand is that I get a U1065 error that is supposed to be an IPM error. Why would the Diagnostics show NO errors for that code? It specifically comes up NO IMP CODE. It makes no sense. Please help if you can. Thanks.
