no codes but ses still on
no codes but ses still on i have tried reflashin and nothing i scan it and only get the loss of comunication with pcm. but no codes that will set the light. anyone have an idea
need to reword better i can reflash and read the pcm and everything seems to work ok, but regadles of what i do it does not turn off, if i clear the codes they do clear but it stays on with no codes there. when i scan it no codes come up that usually make the ses light come on,

Here's what my helms says for MIL always on:
Turn OFF ignition, disconnect PCM, turn ON ignition with engine off, observe the MIL.
If it's still on it's related to the instrument panel cluster - test MIL control circuit for short to ground between PCM and IPC...
If it's off - replace PCM.
I'd try resetting the PCM manually first by pulling the fuses method.

thank i will do that i did have a problem with the pcm a few days ago was grounding the 1-2 solenoid all the time had to rewrite entire and worked fine but the light stayed on so maybe while doing the pedal swap i messed up a wire somewhere
