THEFT DETERRENT / KEYLESS ENTRY  ENTRY AND START SYSTEM(for Start Function)  Additional Key cannot be Registered  


DESCRIPTION

If additional registration is not possible, a malfunction of the electrical key transmitter sub-assembly, certification ECU (smart key ECU assembly), engine switch, No. 1 indoor electrical key antenna assembly (front floor), steering lock ECU (steering lock actuator or upper bracket assembly) or door control receiver is suspected.

CAUTION / NOTICE / HINT

NOTICE:
·

If registration of an electrical key transmitter sub-assembly cannot be performed, refer to the Service Bulletin.

·

When using the GTS with the engine 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. 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 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 entry and start system (for Start Function) after confirming that the communication systems are functioning properly.

·

Before replacing the certification ECU (smart key ECU assembly), steering lock ECU (steering lock actuator or upper bracket assembly) or electrical key transmitter sub-assembly, refer to the Service Bulletin.

·

After repair, confirm that no DTCs are output by performing "DTC Output Confirmation Operation".



HINT:

When additional registration is not possible, operation history may be stored in the certification ECU (smart key ECU assembly).

a.

Enter the following menus: Body Electrical / Entry&Start / Data List.


b.

Read the Data List according to the display on the GTS.

Body Electrical > Entry&Start > Data List
Tester Display Measurement Item Range Normal Condition Diagnostic Note
Unmatched Vehicle-ID Key No. (incorrect or correct) Yes or No Yes: Communication malfunction
No: Communication normal 		The vehicle ID registered in the vehicle and the vehicle ID registered in the electrical key transmitter sub-assembly are different (if a key from another vehicle is brought into the vehicle exterior detection area while the doors are locked, "Yes" is displayed for "Unmatched Vehicle-ID" in the Data List).
Other potential causes:
·

An electrical key transmitter sub-assembly from a different vehicle is being used.

·

A communication error due to wave interference.

·

The electrical key transmitter sub-assembly or certification ECU (smart key ECU assembly) is malfunctioning.
