Trac off system will not turn off to allow smogging
Two years ago I had my 2000 Impala smogged and had the same problem. We had to remove a fuse from the driver's side fuse block to disable the Trac system. We tried all the fuses today, but without success. I'm thinking there may have been a sequence or something we reset before, that we missed today..Has anyone experienced this and know the procedure?
