So going through changing somethings with my tuner I checked the DTC's just for the hell of it (nothing comes up on eithe my AI or through the Key) and it pulled up a TCM DTC.

This is what Diablo pulled up:
TCM DTC P1654 - Battery was Diconnected (Flag Only, Not a Fault).


So Any ideas as to what would cause this? I know that I had my battery disconnected about 2 months ago but I have never seen this code pop up. And I have checked it recently do to another issue that I anted to check and there were no DTC's then either.... Im comfuzzled

 

Maybe at one point you left a light on. Interior, etc and it tripped the safety on the battery and the pcm cut the power? Just thinking out loud.

 

I dont know, I doubt I did but i guess its possible. The code didn't pull up on anything else though and I know I just checked everything after I got back from the track last weekend so I now that there wasn't any point that I disconnected the battery though. Its just weird becuase it only popped up on the DSP, not through the key cycle or through my AI.

 

Truckin,
Did your clock lose any time? That could indicate if power had been lost.

 

not that im aware of
