DATA LIST / ACTIVE TEST
1. DATA LIST
HINT:
According to the DATA LIST displayed by the hand±held tester, you can read the value of the switch, sensor,
actuator and so on without parts removal. Reading the DATA LIST as the first step of troubleshooting is one
of the methods to shorten labor time.
(a) Connect the hand±held tester to the DLC3.
(b) Turn the ignition switch ON.
(c) According to the display on the tester, read the DATA LIST.

Even if the switch is not turned ON when the windows are almost fully open, the window will not fully close
as jam protection operates at upper window positions during automatic±up operation.

Remote control mirror motor RH circuit (w/ Driving position
memory)
CIRCUIT DESCRIPTION
SEQUOIA features a driving position memory function, and up to 2 driver positions can be memorized.
The passenger door ECU operates 2 motors built into the remote control mirror. The motors move the mirror
to the memorized positions based on information from the position sensor.
