If this is the first time using this scan tool on this model it is possible this scan tool being used is one that isn't compatible with this model fully.I have seen some cause this issue before and had to use a different scan tool.If this scan tool has been used before on this model with no issues and all fuses are o.k. and another ECM was tried this sounds like a wiring fault to the ECM either at the ecm or leading to it.I would check the wiring to see if any faults are found needing repaired.If this was already checked let me know.
