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.

The following data list can be used when the power window is operated through manual–up operation during
the ACTIVE TEST.

*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.
