Toyota Venza: Wireless-linked Return Function does not Operate
DESCRIPTION
When the vehicle doors are unlocked through wireless unlock or entry unlock*1 operation, the certification ECU (smart key ECU assembly)*1 or main body ECU (driver side junction block assembly) sends the key ID signal and memory call request signal to the main body ECU (driver side junction block assembly). When the main body ECU (driver side junction block assembly) 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.
- *1: Smart Key System
PROCEDURE
|
1. |
CHECK MEMORY CALL FUNCTION (MEMORY REGISTRATION) |
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch ON.
(c) Turn the Techstream on.
(d) Enter the following menus: Body Electrical / Main Body / Data List.
(e) 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.
(f) With the ignition switch off and the driver side door closed, press and hold the M1 or M2 switch. The main body ECU (driver side junction block assembly) will enter electrical key transmitter sub-assembly or door control transmitter assembly 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.
(g) When the manual door lock switch is pressed, check that the buzzer of the front power seat switch LH sounds once (0.5 seconds).
