THEFT DETERRENT / KEYLESS ENTRY SMART ENTRY AND START SYSTEM(for Start Function, HEV Model) New Key cannot be Registered

DESCRIPTION

If a new electrical key transmitter sub-assembly could not be registered, wave interference or a malfunction of the certification ECU (smart key ECU assembly), electrical key transmitter sub-assembly, or upper bracket assembly)*3, ID code box (immobiliser code ECU), electrical key and TPMS receiver assembly is suspected.

The registration procedure to add another electrical key transmitter sub-assembly (without replacing any parts) is called "additional key ID registration".

If additional registration is not possible, refer to Additional Key cannot be Registered.

CAUTION / NOTICE / HINT

NOTICE:: ·

New registration mode can be entered only when no electrical key transmitter sub-assemblies are stored in the certification ECU (smart key ECU assembly).

·

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 Start Function) uses the LIN communication system and CAN communication system. Inspect the communication function by following How to Proceed with Troubleshooting. Troubleshoot the smart entry and start system (for Start Function) after confirming that the communication systems are functioning properly.
