THEFT DETERRENT / KEYLESS ENTRY SMART ENTRY AND START SYSTEM(for Entry Function (except NR Series)) Entry Lock/Unlock Functions and Wireless Functions do not Operate After New/Additional Key ID Registration
DESCRIPTION
If all of the following conditions are met after an error message is displayed on the screen of the GTS during registration, or after performing new key ID registration or additional key ID registration, it is suspected that there is an ID code registration failure between the certification ECU (smart key ECU assembly) and main body ECU (multiplex network body ECU), or there is a certification ECU (smart key ECU assembly) or main body ECU (multiplex network body ECU) malfunction.
It is possible to start the hybrid control system*1 or engine*2
Wireless door lock/unlock operation is not possible
Entry lock/unlock operation is not possible
Also, if the hybrid control system*1 or engine*2 does not start, refer to the following and perform troubleshooting as the suspected cause is a malfunction of the electrical key transmitter sub-assembly, smart entry and start system (for start function), etc.

When using the GTS with the ignition switch off, connect the GTS to the DLC3 and turn a courtesy light switch on and off at intervals of 1.5 seconds or less until communication between the GTS and the vehicle begins.
Then select Model Code "KEY REGIST" under manual mode and enter the following menus: Body Electrical / Entry&Start(CAN). While using the GTS, periodically turn a courtesy light switch on and off at intervals of 1.5 seconds or less to maintain communication between the GTS and the vehicle.
·The smart entry and start system (for Entry Function) uses the CAN communication system. Inspect the communication function by following How to Proceed with Troubleshooting. Troubleshoot the smart entry and start system (for Entry Function) after confirming that the communication systems are functioning properly.
·Before replacing the certification ECU (smart key ECU assembly) or main body ECU (multiplex network body ECU), refer to Service Bulletin.
·Check that there are no electrical key transmitter sub-assemblies in the vehicle.
·After repair, confirm that no DTCs are output.
·Inspect the fuses for circuits related to this system before performing the following procedure.
PROCEDURE
Using the electrical key transmitter sub-assembly that was used for key ID registration, check if the hybrid control system*1 or engine*2 starts.
- OK:
Hybrid control system*1 or engine*2 starts normally.
