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.

*1: If the jam protection limit switch is turned ON, the jam protection function will stop.
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.
HINT:
The following data list can be used when the power window is operated through manual±up operation during
the ACTIVE TEST.

INSPECTION PROCEDURE
1 Check the jam protection pulse sensor circuit using DTC check (See page
DI±1904).
CHECK:
Check if DTC B1232 of the multiplex communication system is output.
OK:
DTC is not output.
OK Proceed to next circuit inspection shown in
problem symptoms table (See page DI±1782).
NG
2 Check jam protection pulse sensor (See page BE±69).
NG Replace the power window motor.
OK
3 Check wire harness and connector between jam protection pulse sensor and
driver door ECU (See page IN±35).
NG Repair or replace wire harness or connector.
OK
Proceed to next circuit inspection shown in
problem symptoms table (See page
DI±1782).

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.
