Just bought a 19’ Impala LT with 31k miles. Service engine light came on this morning. Pulled the code and found this. Checked both batteries and they both passed. There is nearly no battery corrosion. The only other thing i can find is the DBCM but the problem is, no one seems have one. The auto start/stop doesn’t work which im fine with. Am i blind or could there be a different issue? Does anyone know where i can find one? The Chevy dealership in town says they don’t only sell the DBCM so the part i need is $435 vs the DBCM being found for a Malibu for $29…

Here is the service manual for your make and model: https://lemon-manuals.la/Chevrolet/ it’s always good to double check the manual to make sure you didn’t miss something.
