If you have all or most of the following fault codes stored, then the body control module (on left side of engine compartment) should be checked for water damage by removing from its connection cradle and check for connection problems underneath and also the ignition coil should be checked/replaced. Only after this has been checked should the engine ECU be considered as a possible cause of these fault codes.
