*1: When the ignition key is not in the key cylinder and the back door is locked, turning and holding the key
in the back door key cylinder in the lock position for 1.5 seconds or more activates the driver door ECU to
operate the power window motor and close the power window.
Similarly, turning and holding the key in the back door key cylinder in the unlock position for 1.5 seconds or
more when the back door is unlocked will open the power window.

2. ACTIVE TEST
HINT:
Performing the ACTIVE TEST using the hand±held tester allows the relay, actuator and so on to operate
without removal. Performing the ACTIVE TEST as the first step of troubleshooting is one of the methods to
shorten labor time.
It is possible to display the DATA LIST during the ACTIVE TEST.
(a) Connect the hand±held tester to the DLC3.
(b) Turn the ignition switch ON.
(c) According to the display on the tester, perform the ACTIVE TEST.

Remote control mirror motor LH circuit (w/ Driving position
memory)
CIRCUIT DESCRIPTION
SEQUOIA features a driving position memory function, and up to 2 driver positions can be memorized.
The driver 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.
