Has Anyone ever sene codes display in the IPC when the ignition is turned off? Once I saw 22 and today 33. I have an internment Unknown driver,I thought it was the driver DDM because when I unplugged it went back to normal that combined with the nice duct tape job the PO had holding it together made me think this was my culprit however even though I unplugged it completely it can back again. Maybe it is the Passenger one. Spent the day yesterday looking at, cleaning and re-tightening ground points.unknown driver still appears but its not happening as much.

 

I may have fixed it, maybe someone here knows the system better than me, PO removed air suspension and added springs but left the compressor and such, I read that removal of a relay ensures the lights don't come on, I found that same relay in the glove box. My theory is the motor on the compressor is bad along with a non-existent ground wire when I removed the system I cut the harness on the module side ensured all the wires were individually heat shrunk and added another for a cap then reconnected it to the vehicle harness and finally tucked it away. I looked at the SP205 junction and couldn't find the air ride on it anywhere and unsure if the systems are connected, however after a long drive with vehicle everything is working with no unknown driver. I also do not know if removing relay also removes power from the module

 

I found the drawing for the SP205 and I see the airsuspension Module is connected to it
