have you checked the suspension control module?i replaced everything with stock - fronts, rears. compressor. i originally was not going to replace the compressor & opt to rebuild but even i - the self proclaimed rebuild queen (some may argue cheap. i prefer frugal, + it has 300k so anything i don’t have to drop a stack on - i try not to) can’t do much with a pile of rust. so i bought a new oem one .
i have an autel maxisys mini with current , active subscription & updated as recent as today. it can pull all codes & perform all functions of the tech2 short of programming modules as i don’t have a j2453.
im getting codes C0575, C0590, C0580 - all but driver left damper actuator circuit open. i’ve checked all fuses, the relays, the ALC relay under the fuse box. i have a p200 power probe that can do all electronic stuff. i tested the relays with that. they are functioning.
the only thing i’m curious about is the possibility of a delete for the auto ride being installed prior to me. if so i can’t find it. i don’t have any codes for service ride control & never have. i should absolutely have had them since my suspension system was a rust encompassing facade made to look like a suspension system.
everything is brand new. i’m lost. help
when i active test - the dampeners get no reading.
if you have rust the module is probably rusty as well, it should be up under the spare, might be worth a shot to try and clean up the connection
