    It's the last code it flashes when it's done flashing active fault codes, sorta the "end code"

    Hey buckeye, you say you have the same truck how is your truck with keeping air pressure. How often does the compressor cycle when you driving on highway? Mine cycles every 4-5min on the highwAy

    as far as I know sys 25 related to sleeper HVAC. looks like Valeo branded blower is malfunctioning.

    If its bs then why did the code just pop up as my air in the cab went completely out? And the air in the sleeper is about half as powerful now.

    I meant BS because it will not derate the engine or slow down to 5 mph... Any fault means something is broken or not working properly.
