    This is a body controller code, not engine. It is for TEM AUX switch #2 data erratic or incorrect. Where and how are you reading this code?

    94 - 1, Fuel pressure below normal
    597 - 2 Brake switch circuit fault, (they all have this, ignore it)
    1551 - 2 HVAC temp blend door stuck

    The last codes are all body controller. You are likely looking at a fuel pressure issue. It has been very cold in many areas that last few days. The least bit of water in the fuel is causing big problems all over. Try to change your filters and retest.
