Have these two codes on a unit today. SI wants others codes checked and software ware checked. No other codes and common powertrain controller software is up to date. Replace CPC next step. Anyone ever saw this? Would it be worth my time pulling diagrams and checking circuits at the CPC.

Check the ambient temp sensor in the drivers mirror for opens or shorts for the 609. Ignore the 628 until all other faults are corrected.
