POWER MIRROR CONTROL SYSTEM (w/ Memory) > Wireless-linked Return Function does not Operate

DESCRIPTION

When the vehicle doors are unlocked through wireless unlock or entry unlock operation, the certification ECU (smart key ECU assembly) sends the key ID signal and smart memory call request signal to the main body ECU (multiplex network body ECU). When the main body ECU (multiplex network body ECU) receives the signal and the driver door is opened, the ECU sends the memory call command signal for the received key ID to each outer mirror control ECU assembly. On receiving the memory call command signal, each outer mirror control ECU assembly moves the mirror surface to the stored position.

INSPECTION PROCEDURE

1.CHECK AUTOMATIC MEMORY CALL FUNCTION (MEMORY REGISTRATION)

  1. Connect the intelligent tester to the DLC3.

  1. Turn the power switch on (IG).

  1. Turn the intelligent tester on.

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

  1. After performing any of the following procedures to link the key and a switch, check the Data List to confirm that the key and switch have been linked.

  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 position control ECU and switch sounds once (0.5 seconds).
