    regarding P0504. I had a short on my trailer a while back, but replaced trailer wiring and ebrake controller. All seems fine since. I guess that would not affect smog readiness though.

    Ahhhhh. I'll give it a few days to see if it cycles like the WUPASS did. I hope I didn't plug it up. I drove it for 2 years w/no plate and turned off via tune. I wonder what kind of test it undergoes to pass internally. Thanks for catching that.

    If you have a way of monitoring egr command state you should see it cycling open and close, i am not sure on the percent open it will command, when it is idling and up to minimum temperature. 135 degrees i think

    Ok, the EPA counter went up to 1. Looks like I just need to drive it a few cycles now.

    WUPEPASS=1
    WUPASS=1

    UPDATE1: Ok, I think I figured it out. Today, ecm reported a P0128. Seems the thermostat is not allowing it to get hot. The temp has be running cold on the first large white line now for about 2 months. Previously it ran closer to 190-200. It does appear to have about a 1/2 container of fluid in the coolant tank.

    UPDATE2: Problem Solved. The thermostat one or both were bad. As soon as I installed new ones, the temps when back up properly allowing heat cycling.
