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.

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