POWER MIRROR CONTROL SYSTEM (w/ Memory) > Wireless Transmitter Memory Function does not Operate

for Preparation Click here


DESCRIPTION

The key ID can be registered to be linked with each of the M1, M2 and M3 seat memory switches. The key ID registration procedure should be performed while the electrical key transmitter is in the vehicle, the power switch is on (IG), and the driver door is closed. When the registration is completed, the buzzer will sound as an answerback.

INSPECTION PROCEDURE

5.PERFORM TRANSMITTER KEY RECOGNITION CODE REGISTRATION

  1. With the power switch off and the driver side door closed, press and hold the M1, M2 or M3 switch. The main body ECU (multiplex network body ECU) will enter transmitter key recognition code registration mode to allow a key to be linked to mirror surface memory position.

    HINT:
    If the memory switch is released before entering registration mode, the memory switch will not enter registration mode.

  1. When the manual door lock switch is pressed, check that the buzzer of the front power seat switch LH sounds once (0.5 seconds).

    OK:
    The buzzer sounds when registration is completed.

Go to step 9
OK


6.PERFORM MEMORY DELETION

  1. Enter the following menus: Body / Main Body / Data List.

  1. After performing any of the following procedures to cut the link between the key and switch, check that the Data List for the applicable key changes to NONE.

  1. With the power switch off and the driver side door closed, press and hold the SET switch. The main body ECU (multiplex network body ECU) will enter transmitter key recognition code deletion mode.

    HINT:
    If the memory switch is released before entering deletion mode, the memory switch will not enter deletion mode.

  1. When the manual door lock switch is pressed, check that the buzzer of the front power seat switch LH sounds twice (0.1 seconds each time).
