REBOCARDO

With the engine not running and the PCM removed from its bracket and out under the hood but still connected to the harness, I get the 512 code.BTW, per my previous post on the forum here, I have ordered a new pcm from ECUDIRECT. If all goes well, it should be here early next week. In your research, did you happen to find anything on the logic of the PCM that causes it to put the vehicle into safe mode. I would think a PCM main power loss or loss of return (PCM ground ) would do that but I wonder if there is anything else.
Thanks
