ERASING THE DIAGNOSIS CODES
Connect the MUT-IIto the 16-pin diagnosis connector and
erase the diagnosis code. (Refer to GROUP 00 – How to
Use Troubleshooting/Inspection Service Points.)
Caution
Turn the ignition switch to the LOCK (OFF) position before
connecting or disconnecting the MUT-II.

1. Install the glass to the window regulator assembly.
Caution
(1) As fully open position which is programed in the
power window-ECU is released (initialized), the
window regulator assembly should not be
operated until it is installed to the glass.
(2) The clamping prevention function does not
operate the first time that the glass is fully closed.
2. Press the power window switch to fully-open the glass,
and then return the glass toward the fully-close position
about 30 mm each. In the fully-close position, keep on
pressing the power window switch for 0.5 second or more.
NOTE
This operation will program the power window-ECU.
