THEFT DETERRENT / KEYLESS ENTRY  SMART ENTRY AND START SYSTEM(for Entry Function, HEV Model)  Driver Side Door Entry Lock Function does not Operate  


DESCRIPTION

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

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), refer to Service Bulletin.

·

After repair, confirm that no DTCs are output.

·

Check that there are no electrical key transmitter sub-assemblies in the vehicle.



PROCEDURE

1.CHECK POWER DOOR LOCK CONTROL SYSTEM
a.

When the door control switch on the multiplex network master switch assembly is operated, check that the doors unlock and lock according to the switch operation.

Turn the ignition switch off.


ii.

Open and close the driver door.


iii.

Hold the electrical key transmitter sub-assembly at the same height as the door outside handle assembly LH and approximately 0.3 m (0.984 ft.) from the driver door.


iv.

Touch the lock sensor of the front door outside handle assembly LH (groove on the front door outside handle) with 2 or more fingers for 2 seconds or more.

HINT:
·

If the door does not lock even when touching the lock sensor for 2 seconds or more, touch it with your palm.

·

When checking the operation of the lock sensor again, make sure to perform the procedure from step (1).

·

When checking the operation of the entry lock function several times, it can be operated up to 2 times consecutively. To operate the function 3 times or more consecutively, the doors need to be unlocked once. However, this is only for the entry lock function, other door lock operations, such as a wireless door lock operation can be performed consecutively.
