Diagnostic Procedure
WARNING: This page is about a different car, the 2002 Dodge Intrepid, 2002 Chrysler Intrepid, 2002 Chrysler Concorde, and 2002 Chrysler 300M. However, it is still accessible from the selected car via links, so may be relevant.
If Miller Transmission Simulator (8333) will not power up, possible cause may be an open transmission control relay (such as in limp-in mode). Check for transmission control relay DTCs. This also could be an indication that transmission simulator is not connected correctly to vehicle. Ensure simulator is connected correctly. Check simulator ground cable connection. Repair as necessary.
