THEFT DETERRENT / KEYLESS ENTRY  SMART ENTRY AND START SYSTEM(for Start Function, Gasoline Model (NR Series))  Security Indicator Light Does not Blink  


DESCRIPTION

·

The certification ECU (smart key ECU assembly) blinks the security indicator light when the immobiliser is set (engine switch off).

·

The certification ECU (smart key ECU assembly) receives the security indicator light signal from the main body ECU (multiplex network body ECU) via CAN communication when the theft deterrent system is in the arming preparation state or alarm sounding state. Then, the certification ECU (smart key ECU assembly) blinks the security indicator light.

CAUTION / NOTICE / HINT

NOTICE:
·

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(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.
