I've been having the Odo Err displayed on my dash instead of the miles for a while. From forums that I've looked at I noticed that a new CCM fixed people's issue. I noticed that my when I pressing the TRIP ODO, FUEL, and TRIP aren't doing anything to the gauge, but if I check for codes the buttons do work to get me through the different sections. Does this mean I need a new CCM? If so, how would I get the new CCM programmed to display my current mileage? Thanks

Tech1 with ccm cartridge. A Delco authorized service center maybe able to program it. Check with local dealer for if there is one locally or it would need sent out.

He rebuilds and programs CCM/BCM's. Or he used to, at least.
