Thank you I will run these past my tech in the AM. Yes when key is on MIL stays lit up even during crank and another PCM has shown the same. I'll update his findings on what you've all suggested.

Maybe could explain the new faults they are a C1095-Hydronic pump circuit fault, B1354- Ignition run/accessory circuit fault, B1458- Wiper washer pump circuit fault, P0500- Vehicle speed sensor fault.

Okay so here's what we've got up here. A customer came in with a no start no crank condition with a check engine light on. Connection of Snap-On Verus pulled our attention to a PCM failure, using a DVOM from fluke our tech diagnosed internal resistance was to high for PCM function and asked to replace the part. PCM was replaced and and some symptoms had gone away however now we had some new codes. Another tech took the job and using his fluke DVOM and verus live data has confirmed PCM function at PCM however when trying to reprogram PCM or diagnose PCM it will not communicate to anything else. I've stuck my newest tech fresh from college on it to see if maybe a younger fresher mind can find it and I've watched him scratching his head with a DVOM, O-Scope, and the Verus in his hand. I'm sure we're probably over thinking something about this but I'm not sure what. Currently we're pulling abs code, and a few others I can post detailed if needed but nothing on PCM until you try to talk to the PCM.
