Toyota Yaris: Power Window Control System / All Power Windows do not Operate with Driver Side Door Key Cylinder or Wireless Transmitter
DESCRIPTION
Wireless Transmitter-linked Function
-
When a key switch is pushed: 1) the door control receiver receives the wireless door lock signal; 2) the door control receiver sends a signal to the main body ECU (multiplex network body ECU) through the certification ECU (smart key ECU assembly); 3) the main body ECU (multiplex network body ECU) sends the operation permission signal to the power window regulator motor assemblies; and 4) the power window regulator motor assemblies are activated.
Key-linked Function
-
When the driver door key cylinder (key linked switch) is turned and held: 1) the door lock motor receives the signal; 2) the main body ECU (multiplex network body ECU) sends the signal to the power window regulator motor assemblies; and 3) the power window regulator motor assemblies are activated.
CAUTION / NOTICE / HINT
NOTICE:
-
These functions are set through customize settings, as they are off by default.
