Hi all,

I am having another issue with the Aspen. The truck starts and turns off right away. I’m getting a “no bus” message in the display. I am wondering if the PCM is wet or has a loose connection and would like to check the 4 plugs.

Can someone advise or provide a picture of its location? 5.7L.

If I unplug it and plug it back in, will it need to be reprogrammed? I do not want to go to the dealer and get a new PCM if there is simply some corrosion or a loose connection.

Need this truck running ASAP as it is my only transportation, any suggestions or comments are appreciated.

Thanks,

 

Replaced ECM to solve issue. (for those who have the problem in the future)
