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).

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.

2. |
READ VALUE USING TECHSTREAM (D-DOOR TRIGGER SWITCH) |
(a) Turn the engine switch off.
(b) Open and close the driver door.
(c) Hold the electrical key transmitter sub-assembly at the same height as the door outside handle assembly and approximately 0.7 to 1 m (2.30 to 3.28 ft.) from the driver door.
(d) Read the Data List according to the display on the Techstream.
(e) Touch the lock sensor of the front door outside handle assembly LH. HINT:
HINT: 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. OK: The Techstream display changes correctly in response to the operation of the front door outside handle assembly LH. |
