Answer
Hi, Fernando.  I'm not intimately familiar with the wiring harness in the vehicle, so I see that there are two basic potential possibilities:

1.  The wires are in place for the communication with the transmission control module (TCM) but are not used.  In this case, if either wire for the communication network is shorted to ground, an error may occur.  

2.  The incorrect engine control module (ECM) is in your vehicle or the ECM is defective.  In either case, this would require replacing the ECM.

My recommendation would be to first register for an account at www.hmaservice.com so you can view the MFI (fuel injection) schematic for your car there.  Then, check to see whether the TCM communication wires are present in the wiring harness.  If so, check to see if they're shorted to ground.  If not present, replace the ECM.
