Truck stalling with no bus error
just in the past few days my truck has been stalling at idle and while driving with on occasional no bus code, i played with the wires and grounds near the PCM and noticed a relay clicking while jiggling the plug closest to the driver side on the PCM, i'm guessing i need a new one? i did clean the connectors and added dielectric grease
im not entirely sure but when it stalls driving or idiling it says no bus and comes back once i wiggle the ECM connector closest to the driver side. i switched out the ASD relay thinking that was it but i had my buddy who is a heavy duty mechanic look at them and said they were all good
Might be a failed PCM..... Try just pressing on the connector next time it fails..... If that fixes it, check out the connector itself, make sure it isn't diry/corroded/etc.If that all looks good.... probably PCM time.
damn at least they're not super expensive haha, i was going to zip tie the connector and hopefully it keeps it secure until i can get one. do you know of any good rebuilders or ECM sellers? i'm in canada

No. I don't..... None of 'em seem to have a very good reputation... Best bet is to try and source one locally. Major parts stores, etc. That way, if there is an issue, you can speak to someone face to face to get the issues corrected.
Yeah, parts for these trucks are becoming fun to find..... But, considering mine now qualifies as an 'antique'..... shouldn't come as a surprise.
