@Sentinel1201 Did you get a fix for this issue? I’m having the same issue with my AMP power Steps.
Hello @Livnitup I am having issues with my OBD port and wondering if there is a setting in Forscan that can help. Here is the issue: I have the controller for my AMP power steps plugged into my OBD port. It will work fine, but intermittently stop working after truck has been running or idling for a while (either my generator is working or we are sitting in truck for extended periods). If I unplug OBD connector for the powersteps and reconnect, it will immediately start working again for a while till problem repeats.
Already eliminated faulty ground, checked connections, zip tied controller to the port itself to eliminate it shaking loose being a cause, but no effect.
It seems the truck stops communicating with whatever is plugged in to OBD after it has been running for a while. Is there a timeout feature for the OBD port that I can disable via forscan??
EDIT: Here are the stored DTC's I just pulled via Forscan. I have disabled idle shutoff via forscan and it seems to be throwing a code? I wonder if my OBD losing connection with the AMP module is related to idle shut off somehow? There are also many DTCs for lost communication with trailer brake controller, lighting control module, etc. which surprise me.
