    2004 Trailblazer P0606

    I hooked up and pulled DTCs... I have 4 of them but one is potentially a major issue...
    [] P0128 - Coolant Thermostat
    [] P0606 - Control Module Internal Performance
    [] P0016 - Crankshaft Position - Camshaft Position Correlation Bank 1 Sensor A
    [] P0136 - HO2S Circuit Bank 1 Sensor 2 (Old) (Immature)

    According to the reading I did tonight the P0606 issue was addressed in a bulletin (TSB 3164A?) and requires an update flash? Anyone deal with this? If I already have HP will I be able to resolve this or will I need to pay the dealership to get the updated flash?

    I called this morning and spoke with the dealership.. looks like 100.00 for a software upgrade that only they have. Hopefully that's all it takes.


    Thanks!
