    Default 2005 LLY No SRT's are enabled? Wont Pass SMOG California

    Hoping to get some help regarding an issue im having with an LLY. I typically get quite a few trucks in my shop (in southern california) that wont pass smog because they have had an after market tuner used on them and even though they were set back to "stock" the readiness monitors still wouldn't enable. Heres the weird issue im having with a 2005 LLY. ive flashed the vehicle with GM's SPS software back to stock and still when I look at it the readiness monitors are almost all set to "not supported" does anyone have an idea? attached is the pictures of what it looks like and the OS

    maybe it has to actually run for a while, I know there are some issues with gasser when resetting an ecm the VW as an example need a period of time to either run a test or complete a test to obtain that readiness status, its a method to prevent a cheated test by resetting an ecm that may not recode again until some other event happens.

    Not sure how the ecm is actually reporting the bits on or off to the scan tool.

    Most if not all of those test are not supported because they are test in reference to a gas motor. I don't know much about California emissions but I would thing the not supported would be ignored when testing.

    Please be more detailed about the failure specifics. I guess you are saying they are failing at the obd plug in??? And NOT opacity?

    That certainly is odd. You should have misfire, comprehensive component and egr supported.

    I didn't think there was a federal version of the LLY. Regardless it should have at least the misfire and comprehensive components even if it doesn't have an egr

    Reguardless what monitors are or are not on the vehicle. I'm just asking if the smog tech selected it as a federal vehicle or California vehicle. I'm a smog tech myself and the other smog guy at my shop smogged a diesel which was a federal truck as a California truck and the smog machine wouldn't communicate
