According to what I'm reading the fault is in the communication between the reciever and the ECU. It may be that the wires are open or shorted, or perhaps the communication process has locked up due to a glitch of some sort. I have seen the process used below to get various components communicating again. I would give it a try. The connector is the OBD connector inside the vehicle. I think you'll find the pins numbered. The ssc refered to is a wire with the proper pins which insert into the connector. Careful use of a paper clip or other wire should be ok.

When the Engine ECU is replaced, ECU communication must be completed.

ECU Communication must be performed between the transponder ECU and the

Engine ECU. Complete ECU communication using the following steps:

A. Insert registered Master Key into the ignition cylinder.

B. Turn ignition ON (engine OFF).

C. Short Tc and CG terminals of DLC3 using Diagnosis Check Wire

(SST 09843-18040 or equivalent) and leave for 30 minutes. (See Figure 11.)

D. After 30 minutes, turn ignition OFF and remove check wire from DLC3

E. Start the vehicle to confirm successful ECU communication.

NOTE:

If ECU communication is not completed correctly, the engine will not start and DTC

B2799 will be set. DTC B2799 will be cleared after engine starts correctly.

Let me know if this helps.
