| Title: THEFT DETERRENT / KEYLESS ENTRY: SMART KEY SYSTEM (for Entry Function (except TMMMS Made)): Driver Side Door Entry Lock Function does not Operate; 2023 MY Corolla Corolla Hatchback Corolla HV GR Corolla [09/2022 - 11/2022] | ||

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 (for driver door)).
WIRING DIAGRAM
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 / Start Key(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 key system (for Entry Function) uses the CAN communication system. Inspect the communication function by following How to Proceed with Troubleshooting. Troubleshoot the smart key system (for Entry Function) after confirming that the communication systems are functioning properly.

CHECK ENTRY OPERATION |
(a) Check the entry lock function.
|
(1) Turn the ignition switch off. |
|
(2) Open and close the driver door.
(3) Hold the electrical key transmitter sub-assembly at the same height as the door outside handle assembly and approximately 0.3 m (0.984 ft.) from the driver door.
(4) Touch the lock sensor of the front door outside handle assembly (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.
