Dealer gets error code C0590-04 on my 2009 Tahoe with Z55 air shock system which they say indicates needing a right rear shock. The labor estimate is $265.00 to install the shock and “reprogram the computer”. I asked the service writer if reprogramming the computer meant to just clear out the “service suspension system” out of the system and he said no that the computer has to be reprogrammed to account for the new shock in the system. I have not seen any mention anywhere on the internet of having to reprogram the computer when a new shock is installed. Does anyone know anything about this?
