THEFT DETERRENT / KEYLESS ENTRY  SMART ENTRY AND START SYSTEM(for Entry Function (except NR Series))  Driver Side Door Entry Unlock Function does not Operate  


DESCRIPTION

If the entry unlock function does not operate for the driver door only, but the entry lock function operates, the request code is being transmitted properly from the driver door. In this case, there may be a problem related to the unlock sensor (connection between the certification ECU (smart key ECU assembly) and front door outside handle assembly (for driver door)).

CAUTION / NOTICE / HINT

NOTICE:
·

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 front door outside handle assembly (for driver door), 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.
