If your car has the 20 pin round under hood connector, it has to have the top cap in place for the under dash 16 pin connector to read DME codes.

There is a shorting jumping in the under hood connector that passes the DME signals to the under dash connector. Make sure the jumpers in the under hood cap are not damaged.
